HOW MUCH DOES A SOLAR & BATTERY SYSTEM COST?

[@OvalRenewables]

Thanks for the video Rob! Its not an easy task working out the payback on these things as it is based on so many variable. Weather, consumption and tariff changes to name a few. We are extremely happy with how much you love the system!

[@DIYJourney1]

Absolutely, so many variables, from every aspect, and it is critical that people take the facts and apply it to their situation. Although you made it look easy, we know the routing was not so simple and its only the tools, experience that got it done in the timeframe. I think, now is the perfect time to say Thank you, we are over the moon, even the wife is impressed. It is, so far worth every single penny. Your guidance from day 1 has led us in to a system that so far has gone far beyond expectations, which is hugely appreciated. …ill certainly be in touch for the next house 😃

[@leemccluskey3063]

Thank you. Finally someone giving an accurate example of cost. I am sick of seeing adverts for solar systems where they say affordable pricing and then want your personal details to quote. I just want to see a rough cost of an installed system without getting multiple calls and emails

[@nikkonch]

Very interesting. Extremely neat installation. We (2 pensioners) had a system installed a few weeks ago on our bungalow which fortunately has a long roof facing directly south, give or take a degree. When we first contacted a company 4-5 months ago there were already equipment supply problems, but we had full confidence in the company (in Hereford) to do their best for us. We ended up with 13 x 370w panels (not black, but actually we really like what we've got), so a total of 4.81 kwh, along with a 10 kwh Solaredge battery system including a 4 kw inverter. Our installation was very straightforward, with the battery and inverter installed on a north-facing external wall just outside where our internal electricity meter is, the panel cables routed through the loft. The installation took a day and a half, three guys on day one, two on the second day. We paid just under £12,000. I am certain that the decision to get a battery was the right one, even though it makes the cost recovery period years longer. The weather here just east of the Welsh border has been quite overcast much of the time since our installation (we missed the heatwaves) and our system has often been producing at a rate of just 1 kw or less - more than enough to keep essential background devices running but not enough to boil a kettle without drawing power from the grid. However, during the day the excess of this low productivity is stored in the battery and gives us a sensible amount to use overnight and on more power-hungry devices on occasion. Our least productive day so far was a paltry 5 kwh, but the best day was 24 kwh. Our battery generally recharges fully by mid-to-late afternoon. On one day we exported 14 kwh which we could not use, but on another only 0.14 kwh. I am slightly disappointed that a 4.8.kwh system often produces so little at this time of year, very late summer or vey early autumn, although I fully anticipated very, very low production in the winter, and correspondingly high production during sunny summer days. The Solaredge app is brilliant for showing you exactly what is going on, almost second by second - it shows that we are still using 0.25-0.5 kwh off the grid each day, for reasons I don't understand, and of course we still pay a daily standing charge. Actually the real motivation to get a battery was to hopefully get on a cheap overnight tariff (albeit with a higher than normal daytime kwh cost). If we can do this when the power companies put these on offer again, I assume that in the low-productivity winter season for the panels we will be able to charge up the 10 kwh battery overnight at a very cheap rate and use the stored power through the next day without needing to use higher-rate units. We are not a high-consumption family, and if we were I would probably opt for more panels and a bigger battery (or more batteries)? We have no regrets. It is nice to feel that you are in a small way contributing to reducing your own and the nation's need for energy produced from gas or whatever, while at the same time, in the long term, hopefully saving money. But it is a big up-front cost.

[@DIYJourney1]

Absolutely fantastic comment. Thank you for sharing your experience and offering the facts to others. I completely agree. We generally are using as much of our system as possible and having an electric car is allowing that, which is holding me back from considering more batteries, as in essence I have a 74kwh one in my car. Really appreciate the comment.

[@timyang4812]

I have similar set up but paid 15k, north east london

[@DIYJourney1]

Could be worth listing what equipment and size system you have, to help people see the comparison

[@ThePantygun]

kzbin.info/www/bejne/bHnWY2CfpJJjqs0

[@Klunge]

You are probably using the .25kwh from the grid when a large load is switched on, like a kettle etc. Most inverters switch to grid power while it works out if it can ramp up solar production or use the battery, and then does so. These small grid charges add up over a day. My system does the same, albeit a different brand of inverter

[@ekrano]

I had a similar SolarEdge (SE) system installed this week, although a little smaller. 15 x Longhi 405W panels, 3.68Kw SE Inverter and SE battery. £14k. Quoted early this year. We had a long wait for the battery with an original estimated delivery of December. Almost a year from quote to installation, but fortunately the battery arrived August. System works great and pleased I went with SE. Looked at other systems and wasn’t impressed with monitoring applications (e.g Solar Man) amongst other factors. My installer only fits SE and Tesla as a rule but did offer GivEnergy as an option if we wanted it. In addition to the above price we added a Myenergi Zappi charger as we have an EV due. As well as the equipment, spend time looking for a good installer. It sounds obvious but remember anyone can buy the equipment online. We had quotes from people who didn’t give me confidence they had the experience with Solar. Also avoid placing equipment in your loft, some installers will offer this but my research showed it was best to avoid due to heat affecting the inverter.

[@dykey1234567]

Hi, I was wondering how you are finding your Solar Edge monitoring, personally I cant see why the average user would need all that info + the extra cost for it.

[@ekrano]

@@dykey1234567 The monitoring is good, and I am told an upgrade is due in the coming months. I think as the data is available anyway then why not offer it to the user. You don't have to do anything with it and can readily view the performance of the system as it is relatively intuitive. You can download the data if required but mostly I just check the production and self consumption figures.

[@paulcooper5610]

Very good of you to give an honest brake down of the costs of such an installation, We didn't need scaffolding as our panels are only on our garage roof. Obviously trying to get an install at the moment isn't going to be easy as suppliers and installers can charge a premium. Didn't here you mention which Electrical provider you are using, If people aren't aware Octopus are paying 15p per KW for anything you send back and if you are on economy 7 you can fill your 10KW battery for 16p per Kw at night making the system work for you even on days with no sun. Worth mentioning as our previous supplier only paid 1.5p eventually raising it to 5p just before we changed, definitely worth being with the right supplier to maximise the payback on your investment.

[@DIYJourney1]

Thankyou, no problem. Yes we are with Octopus, as I have a EV. My next solar video, it will be mentioned as didn’t feel suitable for this video.

[@davidbarry8454]

Great video. Totally agree that it is worth paying more for an integrated system and also for the quality of the install by Oval. Thanks for taking the time to explain this so clearly

[@DIYJourney1]

Thank you David

[@Johnbro8]

Thanks for sharing, we have had our system roughly two years now 7.5kw battery and 14 panels. Summer savings this year around 92%, winter savings around 50%, but it depends on sunny days mainly. Poor charge days are round about 38%, but in only takes the sun to come out to change that. Also changing the way you use energy, running dishwasher, washing machine and tumble dryer around mid day helps to save money by using the sun. We use a timer connecting to the immersion heater for water heating at optimum times, it’s not foolproof but it works for us. Now with energy prices rising, it comes into its own, just be smart when it comes to energy uses. The downside is your always looking for the sun being out and become a bit nerdy towards your own systems 🤣🤣. Good luck with your systems

[@DIYJourney1]

Fantastic, thank you for sharing. You’ve hit the nail on the head for how we are finding its working. Really appreciate taking the time to share as will help others understand 👍🏼

[@Johnbro8]

We may add a back up battery for power cuts, most of all the common systems fail all off in a power cut. This is to protect the power company engineers, working on the supply side from the grid, effectively stopping your system from shocking them. Some of the more up-to-date systems can have this built in from new, in effect isolating your house from the grid in that event . It also means your system would work in a power cut, as it does need a source of power to work the system. NB:- I was once told anything above 1kw will start to draw part of its power from the grid, as well as the battery. Just be careful of what you connect 👍👍

[@DIYJourney1]

Thats it, I believe the essential circuits are separated out in this instance. Our battery would shut down in the event of a power cut, but to be honest I cant remember the last time we had a power cut, well one that lasted more than a few minutes. Something we’ll consider when the solaredge system can do it

[@Johnbro8]

@@DIYJourney1 Just a bit of an update, had two day’s of rubbish sun ☀️ due to heavy cloud cover. Powered into the battery only 20% per day so you will get disappointing days. I was thinking of power cuts that may happen , an item on the news recently of the probability. Just thinking you have all this power in the battery and no access to it.

[@alibro7512]

Do you have a Solar IBoost installed? It will detect when you are exporting electricity and automatically divert that power to the immersion heater.

I had my solar system installed last March, similar all black panels but as it’s a small bungalow could only fit 12 panels but all face south. I had them installed by the same company that fitted an Air Source Heat pump a year later (paid a deposit to let them know I wasn’t going with another company) so they gave me a hearty discount on the solar, costing £6000! Although the ASHP system for domestic host water and heating cost £18k to install. I get a government grant of £11000 paid over 7 years. We only have oil in the village and the cost of oil has gone into the stratosphere 😱 Scottish power has reduced my monthly bill to £20!

[@spearhrower]

I invested early in solar back in 2012 with a 3.5kw system and it paid for itself twice over now as the original install was only £6k. There were no hybrid inverters or batteries back then. But now there is so I'm upgrading to a Solis 6kw hybrid inverter and four 4.8 kw 48v Pylontech US5000 batteries that were only £1,450 each. All told the upgrade with all the new wiring it will come to just over £9k but it will work in the event of a power cut but most importantly for me is that I can expand the system in the future. A lot of these systems out there have limited scalability or expansion possibilities so if you want to add to the system with extra batteries or panels you can't. The batteries I chose can string up to 16 but with a hub I can have many strings. I've oversized my inverter for 2 reasons, one is that I plan to add more panels and the second is that I want more power avaiilable from the batteries, inverters can only supply from the battery what it is rated at I've had to wait a long time though as the supply madness continues but it was worth the wait as I know it pays for itself fairly quickly.

This panel can put out close to 100 watts kzbin.infoUgkxOqI2yqX0XVrhR2BMJciTWrHJpG8FhJyg when positioned in the appropriate southernly direction, tilted to the optimal angle for your latitude/date, and connected to a higher capacity device than a 500. The built in kickstand angle is a fixed at 50 degrees. Up to 20% more power can be output by selecting the actual date and latitude optimal angle.The 500 will only input 3.5A maximum at 18 volts for 63 watts. Some of the excess power from the panel can be fed into a USB battery bank, charged directly from the panel while also charging a 500. This will allow you to harvest as much as 63 + 15 = 78 watts.If this panel is used to charge a larger device, such as the power station, then its full output potential can be realized.

[@DIYJourney1]

[@bill_heywood]

It is really important to give people this kind of detail and talk though your decisions and the cost implications. As you say it is an expensive capital outlay, but it is also a very savvy investment. Over the long term it will repay the upfront costs many times over and increase the value of your property. I’m looking forward to free miles in spring/summer once I get my solar and an EV. When a tank of diesel is £90 a pop, there are huge bonus savings to be had over and above the savings on home electricity

[@DIYJourney1]

Really pleased you recognise this. This is exactly why In sharing this information, to try help others easily understand to make a decision.

[@video99couk]

Though all south-facing panels gives you more energy output, having panels in two directions like you have will give a longer production of energy over the day. We have 6.4kW of panels all south facing, solar edge optimisers and inverter, Tesla Powerwall 2 and gateway. Installed late last year for about £16k total including fees etc. We're heavy electricity users. It will charge the Powerwall overnight using cheap rate on days when the forecast is gloomy, but charges less when sunshine is likely. I've featured the system on my channel and will do a follow up when it's been operating for about a year. Trouble is with present lead times, people couldn't buy the system now.

[@nikkonch]

I was quite surprised how many hours in the day my new 4.8 kwh south-facing system produces energy. Looking at Sept.19th, its first full day of operation, it started producing at 6.30 a.m. and stopped at 8 p.m. albeit at very low levels, but it reached a respectable 1 kw at 8 a.m. and finally fell below 1 kw at 6 p.m. But yes, in high summer when the sun sets further to the north-west I can see that installing panels on our west-facing roof would give us more power in the late afternoon/early evening.

[@madpete6438]

YES my system is the same - split 90 degrees apart into the Morning array (2.5kw) and the afternoon array (5kw) - it makes the standard curve rise faster flatten for longer and drop slower than a standard (for New Zealand) Due North array.

[@JustMeTalking]

Bird protection... I spoke with an amateur Ornithologist about this, specifically about Pigeons. He told me that Rock Pigeons / Feral Pigeons (Green/Purple necks) are hole seekers, very territorial and will live, breed and die under your Solar Panels. However, not all Pigeons are the same. Wood Pigeons (white necks), are not hole seekers, they prefer bushes & trees. So will walk on and around your roof, but never under the panels. This knowledge saved me thousands... as we have Wood Pigeons, and sure enough... we're safe.

I've just had solar fitted. In Durham . It works perfectly. I'm quite pleased with it .the quality looks excellent. I don't think I got the cheapest and I didn't want it either. But I got a 12 panels plus 6k inverter plus a battery .all fitted .plus scaffolding. I was happy with the instalation .i thought these guys know what thfy are doing but I' was not too happy with the amout of instruction I received .prior . Mabey it was me but i felt it was not sufficient. As I'm learning more from KZbin. The total I wanted to pay was about up to £10k but total cost ended up being just over £14k only time will tell whether I got ripped or what ..I had to wait 3 months to get it fitted .and I think the wait is even longer now . Good luck I'd say do it .but don't dilly dally any longer. As you will pay more and wait longer to get it . The Company I used was called Project Solar from the Manchester area

[@nikkonch]

Although you don't give any details about the panels and the battery, and the prices for these vary enormously, as a non-expert the price you paid seems ball-park fair to me. I had very little discussion with my installers after the initial survey, and the installation team seemed to be working out the best arrangement of the various boxes and leads on the day, but that did not concern me. My Solaredge system seems to run itself without any need for my intervention unless I need to change battery charging times, which the installing company will do for me. I paid just under £12k for 13 x 370 w panels and a 10 kwh battery, but only have a 4 kw inverter. Installation costs were low because we have a bungalow and easy routing for cables, so it only took them a day and a bit. We waited about 4 months for installation. I have absolutely no regrets about installing solar - it's the sensible thing to do. Enjoy your system!

[@UK-Expat-in-USA]

I am in the USA in Las Vegas and had solar installed just over 2 1/2 years ago, we went from spending $2,200 a year to $165 which is the standing charge for the electric meter and being connected to the grid. I liked your video and can honestly say having Solar panel & a Tesla Powerwall installed was one of my best decisions - I'm figure payback will be 7-8 years.

[@Kiran_UK]

Interesting video, I've just instructed an installer on a very similar sized system, 22 panels (split across 4 roof elevations so a bit more scaffold too) instead of 20 but mine came in within £1500 so when you gave your total figure I felt a lot better. The guys we have instructed are also really good with the aesthetics so seeing a neat install reinforces that that was worthwhile too.

Wow - solar costs a fortune in the UK. We have 7.5kw in 2x arrays (with the smart isolators on 4x panels), a 5kw inverter and 12kw modular battery (expands to 24kw for an extra NZ$10k). All for less than NZ$27k installed. At the current exchange rate that is 14,149 pounds total. Now in good old New Zealand we have 83+% of our electricity supplied from renewables (so hydro, solar and wind) - and we have quite decent prices NZD$0.29 per kwh (incl. tax) and NZD$ 0.60 per day connection fee. But I get NZD 0.085 per kwh exported which is pretty low. In New Zealand we get ZERO government support for doing this and it is still worthwhile. We also do not get time of day tariffs either. In the end, we decided that we were setting our energy cost at a fixed price and that 40% of the system would last 15 years (the batteries) and the inverter and panels 25 years. Once we divided the cost to install over these periods and then applied average inflation in electricity prices, it was a complete no brainer - even without any export. Our only regret was getting the smaller battery - we should have gone for the full implementation of 24 kw. Also, The hardware we choose allows us to add another parallel battery and inverter and they use CANBUS to coordinate their activity - also an important feature as the plan is to add another 5kw array with a 2 kw wind turbine and more battery to deal with charging our next vehicle. So the important things are : 1. Buy as much panel capacity as you have roof space. 2. Buy as much battery as you can afford. 3. Get an extensible system so you can grow it using a wind turbine or more solar. 4. Do not get bogged down in trying to calculate whether it will pay for itself - the greed of the energy industry guarantees it. I was horrified at what your politicians are allowing to happen to the citizens of the UK - a legacy of inaction and endemic corruption in your parliament.

Thanks for the effort put in to do the video, I appreciate it's not easy to give up your time to share your experience. Ignore any of the keyboard warriors comments. The installation looks neat. You must be exporting a lot to the grid though? That volume of solar production I reckon your export must be 50%? Getting a battery was a wise move. Solar returns little in comparison to backup storage. We had a similar system installed in April, smaller array but more batteries. Wish I had gone for a higher inverter as only 3.5kw hybrid would be my tip on reflection. Keep sharing your experiences 👍

[@DIYJourney1]

Very kind comment thank you. It nice to response to sensible conversation with likeminded people. First month completed and we have only exported 20% out of 700kwh. Reason being, is I have an electric car. So alot of excess went in to that, Iv had around 1450 free miles is august. We also have planned a hot water energy diverter to heat our hot water via the emersion heater. So I think we will be close to maxing our production. The reason for such a large array, was in the winter months, my theory was, that “alot of little production” will give us atleast an element of useable production or atleast top the battery up with small amounts.

For the system you have installed I think it sounds reasonable. Yes, you could have saved a bit on the inverter/battery, but Solaredge is a good manufacturer. If you watch Artisan Electrics based in Cambridge their installations/systems are between £25~50,000.

Thankyou for this. Yes I think even for us if we were to have this system installed, it would be quite a large amount more.

[@johnwarwick4105]

As 40 year electrician I can say that is a neat job from the bits I have seen. I have had 4kw if solar for 11 years now was a fantastic investment with the feed in tariffs at the time. These got the industry started as without it it was just not viable. Today is totally different with high energy the investment stacks up easily. Having said that I think your projection is in my opinion optimistic ( unless you have an electric car or something. Living in the middle of the country as a rule of thumb 4kw of panels produces 4000 units per year( newer inverters will be more efficient) the problem is 3/4 of this is produced in the 7 sunnier months and the remaining quarter in the winter months when you need it more. Strangle enough during the recent high summer temperatures the max output has dropped alarmingly. Cold sunny days produce the best output. I am sure it will have been a sound investment even if electricity prices drop back

As said in this video, and my other videos relating to solar, I have an electric car that does 35k miles a year. I am very comfortable that the pay back will be around the stated or sooner with reimbursed mileage element and energy prices.

[@johnwarwick4105]

@@DIYJourney1 sorry missed that. Yes going to be great with a car. Curious though as won’t your car be away from the house during the day when the bulk of the solar available? You then you’ll be reliant on the 10 kw battery to battery transfer, guessing this is only about a 1/3 of a tank, but robbing your nighttime energy store for the house. Not a criticism this is genuine curiosity! As just got another 10kw if nearly new panels and debating the options.

[@DIYJourney1]

No, as I work from home/work nights, as Iv always said very specific to personal situation. My journeys are not everyday, but when I do one will be 200+ miles each time, so my car sits on charge during the day following solar production also reimbursed mileage has to be considered. Our usage is on average about 1100kwh per month

[@phil_nicholls]

Nice system. We already have a 4kW East/West system, and we're adding another 5kW next week (scaffolding already up), along with a Tesla PW. £17K for the new system - just over a grand of that is to remove and refit what is already there, as our original 4kW system gets in the way of the new install. Ordered in January of this year, and it's been delay after delay - finally about to see the light! Should be pretty much independent from the grid between March and September, and using mostly cheap rate at other times to charge the battery and EV's.

[@DIYJourney1]

Sounds a fantastic system, Id like some more panels on the east, however we would require planning permission and because of the village we live in, I dont want to add an eyesore as the front of the house is visible, but Im shocked at how much east/west panels are for a full days production certainly a lesson for me. Your price seems reasonable doesn’t it, or comparable to mine.

[@phil_nicholls]

@@DIYJourney1 We're happy enough with the price - particularly when you look at the ROI for such a system (not necessarily the full payback), there's little else to touch it as a vehicle to save money, particularly with the ever increasing cost of electricity. (Also tax efficient, as 'savings' aren't taxed). We're lucky in that we live in a long barn conversion, so the panels are all at one end of the roof, towards the rear of the house, so not really noticeable at all. We would have saved ourselves quite a bit of expense had we just plonked the second set at the front - but like you, we don't want the installation to be too obvious and in the neighbour's faces. While the roof could probably accommodate 20kW+ , if we choose to add more, we'll probably stick them in the garden - one of the advantages of living fairly remotely in Northumberland - land is cheap(er) than elsewhere! It wasn't what I was hoping to spend my pension on - but at least it should stop us getting any nasty energy bill surprises. Though if anyone knows how to produce your own heating oil, I'm all ears! 😁

[@DIYJourney1]

Nice to see someone in the comments section, thinking of bigger picture such as tax on savings. So many variables isn’t there to how they are viable, but more so like you say, reducing/removing the risk of volatile pricing or even just giving long term security on production.

Spent 1.5k on 15x 450w panels, 1.3k on a 6kw inverter hybrid on/off grid inverter that does a little more than what your 2 or three pices of equipment do. 1300 on a 7.5kw lithium battery. So approx 5k for equipment including cables and supports etc. Installation and certification 1k. Where I live the aystem anticipates historically enough sun to generate 10,200 kwh. Sunny where we live. Downside is generating companies only give you a monthly credit against any excess generation you put into the grid. Plus standing charges still apply and excess generation cannot be credited against them. Euros not pounds. Could have got a 70% grant against installation costs but probably would have to wait several yearscto get it back and probably pay 6k as against 1k. (90% of installation done by myself). 1k for wiring and certification.

England isn’t Euro’s so assume Ireland or other. - what equipment did you purchase - As in brand and models? - What is the warranties that are included on those? - Does that equipment have the ability to be dc coupled? - What safety features does that system have, such as the solaredge being able to cut the voltage to the panels in the event of issues, like with optimisers, which you also haven’t mentioned whether you have. - Who certified a self installed solar pv system?

In comparison,, my 3.6 kw panels with 3.6 kw inverter cost £6000 10 years ago. Installation took 4 hrs. Two or three later this would have cost £4000. I am surprised at the small size of inverters mentioned, mine(Aurora) matched the panels yet failed after 5.5 yrs, in UK this had a 5 yr guarantee while in the USA it had 10 yrs. I emailed the company about this but got no response, I repaired it myself and its OK(touch wood) to date. The price changes are due to demand & component shortages but if the war stops tomorrow ....?

[@DIYJourney1]

I would price difference, has many factors: - Quality of equipment - Warranties given - Advances in technology - Normal cost rises each year - Supply & Demand

[@air5002]

A couple of things to bear in mind. Batteries have a lifetime cycle. Unnecessary cycling or cycling to provide power to the grid is incredibly wasteful. Over the lifetime you will reach a point where your batteries need replacing. It might be ten years or more. That means you must factor the replacement cost of items that have lifetime limits. Panels also have limited lifetime. Therefore in say ten years, for sake of argument, you may need to purchase a new set of panels and a new bank of batteries. In ten years time, they might cost a lot more than they do today. I suspect that the technology has come to about as cheap as it will be. However, another factor, in ten years time, the same size panels are likely to be very much more productive. The batteries also will no doubt be bigger capacity. As for the electronics - the inverter - all electronics have a lifetime and can fail. If the equipment is made as in a lower integration of components then it will be easier to repair or replace board components. I'd be interested to hear what others think about this aspect of hidden costs over the term.

[@DIYJourney1]

Im a little confused why people say this, firstly, what is the point if having a battery to store energy to be used at a later time if you cant discharge and recharge it. This leads in to my next point as in warranties, surely that is anyone port of call and people suggesting 10 years in the comments, are purely stuck in the past. As you say technology advances, manufacturers are happy to warrant these much more now so we all need to move on a forget about historic information. My panels have a 25 year power output warranty guaranteeing 85% at 25 years. Battery has a 10 year warranty with unlimited cycles and allowing 70% energy retention at the 10 year point. Inverter has 20year warranty with the ability to extend to 25 years. Now considering the above, and a payback sub 7 years for me, it is a very viable option, and as we move forward should improve, things do break and as long as the warranties cover it that should be the first decision and one of the reasons I chose the route I did and would recommend that for others also.

[@MichaelPickles]

A little tip, If you want to upgrade your supply to your house to three-phase just ask for a fuse upgrade with your local DNO. Invoice will be free If you say you're going to be attaching batteries and solar. they will charge you for an invoice.

Given a base fuse upgrade request with our DNO is £140+vat, I doubt a full upgrade to 3 phase would be free. Could be wrong but I can only go off there website.

[@jax5281]

Thanks for this video, we had someone come around to quote us today for panels. I am curious about your inverter comment, basically we would like to future proof our home, we don't have an EV now but the next cars we buy almost certainly will be. General rule of thumb is that inverter should match the output of the panels it seems, does having an EV change that?

[@DIYJourney1]

I think that is a fair way to look at it. Match the inverter to panel peak output. Our peak is 8kw but our inverter is 5kw. I did anticipate we would reach 8kw as much as we do in the sunnier months. Probably advice I should of been given, but also we increased our panel array size from 5-8kw quite late on, so to do this would of meant, further delays, and more cost for another DNO approval.

[@jax5281]

@@DIYJourney1 Great, thanks so much for response!

[@JustMeTalking]

Just to add to this... Your Inverter should be sized to your expected peak output... not the Solar Array Size. For instance, if you had two 4kWp arrays (East / West facing), the peak power would be LESS than a single 8kWp array (South facing). Also, during Summer Heat, your Solar Array can lose 20% of it's peak power due to heat buildup. So the inverter size needs to take these considerations into play.

The whole system cost A$24,000 fully installed on a single storey house. The only regulatory bodies that have to be notified are the governments, federal and state for the rebates to be paid and the state electricity distributor to monitor the amount of solar being installed. Our feed in tariff has recently been reduced to 6.5c per kwh, was previously 7.5c. What is the feed in tariff in the UK? Another point of interest is; we are now restricted to exporting no more than 5kwh per phase due to the amount of solar energy being exported at the middle of the day. This may change if other uses are found for the excess solar, eg hydrogen production. Thanks for showing us how it works in the UK.

[@DIYJourney1]

Its hard, in hindsight id of gone 8kwh…but…its not actually much of an issue with having a dc couple battery (explained in my installation video), meaning the extra 3kwh can still be used to charge the battery if the house load is maxed. Im finding 5kwh is ample for the house usage, but limited for the car charging I just don’t get the 6mile an hour in my car charging when the system is peak.

Whilst the "payback" period is important to some, I will be looking at this from a return on investment 1st. If you assume a £15k cost and that you are fortunate to have the cash on deposit to finance it, your £15k in the bank will earn you c £300 (est 2% without compound interest). If your energy cost is c £2,000 a year then the return on your investment is over 13.33% - assumes that you are self sufficient. Your total return less what you were earning from the bank is 11.33%. That seems a very suitable return on savings put to better use!

All items come with a reasonable warranty, the battery is 10 years and they guarantee the energy retention to be 70% at 10 years. Solar panels are 84.8% at 25years.

Great video, thanks for sharing. I had a solar system installed in January this year using 12 x 370W JA panals, Solar edge optimizers, Solar edge 3.68kW inverter and a solar iBoost to heat the water. I got the quote and installation before the cost of leccy went mad so I think I was lucky to get the whole thing installed for £6k. My only complaint is the wifi in the inverter is very flakey as it loses connection one day and reconnects the next. This has been the pattern since it was installed but is not effecting the operation so I put up with it. At some stage I plan to build a DIY battery for it but will probably make that a separate system to the house electrics. Have you signed up with a company yet for generation repayments? So far we have generated 3MWh since February and I live in Northern Ireland which is NOT a sunny place. Most of the leccy generated has been either used by us or used to heat the hot water tank by the immersion heater through the IBoost.

Hi pal, Ive got a question regarding your solar panel system. You have 20 solar panels which the total power outcome is 8,100 watts and it is 2 string and you have a 5kw inverter. Are you able to put a 5kw inverter on the system because I bought a 5kw type of inverter and I have 20 panels as well, are you able to connect it? Is it not too much? Thanks Pal.

[@DIYJourney1]

Hi, Excuse my knowledge, but I believe its subject to the inverter capabilities and depending which you have. The solaredge inverter allows for oversizing of 150% (if i remember correctly). Lesson learnt for me, if your likely to produce with the full array, I would match your inverter to the panel array size if you can. Of course you have your inverter so appreciate likely not doable.

[@zombiestyled]

Honest video. Like that 👍👍

[@DIYJourney1]

Thankyou, hope it helps.

[@robertamurrant]

Does your system/any system have smart export? Ie setting rules like if the variable export price is more than 40p/kwh, export as much as possible from the battery until the battery gets to 45%.

[@DIYJourney1]

Its not something iv looked at so unsure. Im using my system with thought of using as much of the produced energy as possible. I know our export rate sits at 4.1p/kwh currently so isn’t worth exporting. Iv not seen any at such a high level as you mention but do believe octopus do a tariff that tracks the pricing, so whether it can adapt to that Im unsure.

[@MrGhostTube]

Nice video. Very clear. Thanks.

[@CelticStone]

our full setup 100% offgrid, total price around 4000 quid ruff conversion from nzd. 1st question.... what do I actually need.... then go from there

[@DIYJourney1]

Agreed and the reason I did the video to help people grasp a rough cost estimate for there situation with the equipment they need.

[@Mr35000000]

Great Video. I am totally bought into the concept of solar with a battery. My only issue is committing to remaining in my property for the payback period. I believe taking them with you is not straightforward and they cannot be "rectified" in a new property?

[@DIYJourney1]

Its a great point that, and a tricky one and is one of the comments I made at the end of the video as to what can be used in the payback of them. Meaning, could the cost be added on the value of the house particularly at the current time. I imagine to take with you, you’d just have to pay labour twice.

[@AdrianMcDaid]

Just get batteries perhaps ?

[@pl909uk]

In the last price hike, our supplier put the bulk of the rise onto the standing charge. I think it's a sneaky way to guarantee themselves an income and make the ROI on solar take longer.

[@DIYJourney1]

Our latest increase has seen the day rate double, and the p/kwh increase by 2.5 times. Unfortunately we cant change the day rate but the ROI is certainly there for us.

[@Andrewuk99]

Great vid What is the size of the battery, and what does your house use on a typical day?

[@DIYJourney1]

Thank you, the battery is 10kwh with 9.7kwh useable capacity. Our house not including electric car uses on avg 10kwh per day. With the electric car and using august as my only example, we used on avg 23kwh per day if solar, putting about 1200miles in my car

[@doddsy799]

Hi mate, thanks for the video, i notice at the end of the video you mention your system is around 3x greater than what you need, with that in mind, and all that redundancy, would it be possible for you to come off grid all together? would you have the confidence in the system to do that?. If so, and you were saving your standing charge as well, then the pay back time would be even quicker. Thanks again, Chris.

[@DIYJourney1]

Hi, I wouldn’t have the confidence to do that, from my short experience you would need a very large system and battery for those cloudier days. Always worth having the back up, its worth noting, this video was filmed in August, so our average production was about 40kWh per day, as we reach the end of October this is now around 15kWh so as we progress to darker days I imagine this will fall further, as expected. We are finding ways to use as much of the redundancy as possible, such as filling our electric car, heating our hot water and recently started using our electric fire to heat the downstairs. Hope that helps.

[@doddsy799]

Thank you, yes indeed it helps, I look forward to further videos. Thanks again, Chris.

[@DIYJourney1]

Thank you, no problem,

[@timmcvittie436]

Thank you. Very interesting and informative video. 👍

[@DIYJourney1]

Thank you, I hope it helped.

[@jimmyc33]

Great video - interesting stuff. Regarding the payback period though - if you're saying that your payback period is 5-6 years on a cost of £18,500 then when you do the maths on that it looks like this doesn't it (for simplicity these figures assume you use everything that you generate which should be possible with the battery, and feed nothing back to the grid): Total cost - £18,500 Payback - 5.5 years Saving per year - £3,363 Energy being generated per year to achieve that saving: 3363 / 0.34 = 9891 kWh per year. Is that right - are you generating nearly 10,000kWh per year with this setup?

[@DIYJourney1]

Honest answer, I don’t know yet, I think it could be achievable. My experience so far from august as thats when our was installed, we saw regularly 35-45kwh of production in a single day. Currently we are seeing 17- 20kwh so will have to see how it pans out over the next 12 months. Even working it out at 7 years I feel 20kwh is very achievable as an average per day and is a good pay back. We need to also consider this usage is for an EV also so whether you could use an element of fuel savings if the car is priced like for like, in my instance it is, but as said, looking at it simply from a production point of view it “could” be possible lets see what the good old British weather throws at us 😃

[@JustMeTalking]

We have a UK based (West Midlands) 7.2kWp Solar Array (East / West facing) with a 5kW inverter and produce 5.7 MWh per year. We actually used 98% Solar last year, exported 2% 27 kWh of battery storage with 10kW discharge capability, Smart Meter and low cost Tariff. An electric car with 75 kWh storage, a 22kW 3 phase charger and it does 15,000 miles per year. Our house uses about 16 MWh per year, with Heat Pump, Induction Cooking, electric showers etc. I calculated ROI being 4.5 years for Solar Array, 6 years for battery storage.

[@paulspencer3896]

Hey Rob Bril breakdown of your solar panels, I ve been thinking about installing some myself

[@DIYJourney1]

Thank you, hope it helped, any questions you know where I am 👍🏼

[@ShortVersion1]

Great job with a tricky subject. It's very hard to tell people the costs of these sorts of things, because not only does the price of equipment vary, but also the labor around installation, AND the price associated with energy usage. We got batteries and solar over a year ago, and while the price has been the last thing on our minds, it's all other people want to know. Problem is, it's changed since we paid. We literally got a big unexpected check back, and now some of the people we told are walking around with outdated ideas of the cost. Further, energy prices can change so much the ROI reduces greatly. Just this week, I got the option to import/export grid energy with the battery, which could "save" another $1200-1500 a year... I am hesitant to even estimate that, but it seems like it could cut our ROI in half.

[@DIYJourney1]

Your absolutely correct. Very difficult, I just feel this is the right thing to do.

[@clivewilliams8656]

Can you explain how you use the energy in the home to achieve savings and what extra costs were incurred? Do you have electric heating and if so did you install this to use the solar benefits? What about hot water and showers? Have you installed electric amenities everywhere? As an example, if you installed say, an 11kW electric shower could a family of 4 shower effectively each morning using only stored energy?

[@DIYJourney1]

For the house, the appliances we have: - Electric Fire - Induction Hob - 2x Ovens - Washer - Dryer - Dishwasher We are awaiting a Solaredge hot water diverter which will use excess solar to heat the hot water via the emersion heater. However, I have an Electric Car which has a 74kwh battery so we are pretty much at the limit and using everything, for our first month we put over 400kw in the car which is circa 1300miles of free mileage

[@JohnJones-ri7pi]

Impressive system pal 👍 ordered panels and a battery off eon in March only just had the G99 approved because the DNO’s are swamped with applications, but can’t wait to get it up and running, what energy supplier are you with and what tariff are you on out of interest?

[@DIYJourney1]

Octopus Intelligent as I have an EV. Currently with low production to help support that I charge the battery

[@JohnJones-ri7pi]

@@DIYJourney1 thanks, do you charge your car overnight or can the panels + battery discharge at 7.2kW? Quite a technical rabbit hole these installations - no companies ever seem to offer a full service, do you have a solar iboost or similar to put excess power into the water tank? Heard they’re good

[@DIYJourney1]

I do yes as I do a lot of miles. Currently the solar cant produce anywhere near enough but summer, absolutely. I have a tesla smart immersion, but eventually will have a solaredge diverter
