Great first video. We had installed 6 weeks ago a 10+6 400w system. It was a quick decision as we unexpectedly needed our roof retiling so fitted solar at the same time. Due to this getting a system NOW was not easy, but a recommend local installed managed to fit us in. Understanding the feed in limitations is why our system is a 3.6Kwh (10x400) and 3Kwh (6x400) system. The 3.6Kwh is a hybrid inverter for future battery storage. You are limited to 3.68Kwh going back into the grid without special survey works. So on a good day, the 6 panels can be producing 2.4Kwh and the 10 panels even more, but if the house isn't using it, the hybrid inverter has to throttle back the energy produced from the 10 panels so no more than 3.68Kwh is exported. In the short time we have had it, currently we are pulling from the grid on average 6Kwh instead of the previous 18kwh. So a good saving. We just need to use/store the excess.

[@GaryDoesSolar]

Thanks for the kind words. Yeah, there is so many factors to consider for any solar installation - no wonder that people can get confused and end up ordering the wrong setup. I'm hoping that my second video will be of help, it should go live shortly.

[@johndean1634]

Have you considered what you get money wise from the Feed Back Tariff against not Feeding it Back. And using the full potential of your system. You only need the DNO survey if you use the Feed In Tariff system. Decent battery set up would help as well though for sure and you will need DC Battery rather than an AC battery as you will be charging from you PV array rather than the Grid tied AC battery. Your not doing to bad really majority of the 6Kwh you use could be solved by the Battery you will add at some point as it occurs during the hours when you loose solar power evening time and over night.

Thank you for clear explanation of Basic PV for homeowners! ! 🌞 re: 'Return on Investment' Time...as I have been explaining to U.S. customers for decsdes, they need to ask the utilities... "When will my Electric Bill pay-off??" Of course the Answer is "Never" since buying energy monthly from grid suppliers never has a 'pay-off' & is only Renting your Energy forever!! In contrast, Your own PV system is Owning the energy Source so it Has a payback🌅🗽

I’ve installed both solar, a Powerwall and myenergi equipment to heat the water and charge my Kia Nero. Your right it’s a huge saving especially now with energy going through the roof. However your car analysis is a little wide as one requires a minimum of 1.4 kw to charge the car this means on my charge point I’ve got to set it to combine the grid with the spare solar to reach that 1.4 base line. Before the current price rise and with a small FIT payment, I was the last to take it up before it ended, I’ve worked out that my combined energy bill was little more than £20 a month. We don’t scrimp on energy as my wife love heat but we do live in a modern well insulated Semi Detached. We were able to use our savings to complete the work and it’s over the last four years given us a return of around 8% which was way better than the banks were offering. I really believe it’s time our government! Legislated that all new builds had solar panels and battery storage. It wouldn’t increase the house price by a huge amount but would allow people to make use of solar energy without having to find huge lumps of money, and of course it would increase the value of the property against one that didn’t have any of this equipment

[@GaryDoesSolar]

Sounds like you have a great installation there! Fantastic to hear the ROI you’re getting. With UK rates expected to rise again in the autumn by an eye-watering 64%(!) those who can afford to get solar will get their money back even quicker. I totally agree with you regarding the government’s role with solar - other countries provide more support than the UK, both on equipment purchase and payment for exported kWh. With the price of new homes being what they are, the % extra burden on the price for having solar is low, but the upside for the country in terms of self-sufficiently is huge. Granted, the storage issue needs to be resolved (locally and regionally), but we have the wherewithal to do that. Thanks for the note on EV charging - much appreciated!

Great video Gary, it must have taken many hours to produce.

Thanks very much for the kind words, Neil - you're not wrong. When I started this, I thought it would not take too long to make a video - after all they're only 15-20 minutes long... how wrong I was! It literally took maybe 50-100 hours for each video. My background is in software as it happens. But back then there were no software engineering courses at uni so I did electrical and electronic engineering. Most of my career has been in mobile telecoms (I'm a SIM expert) and I really enjoy presentations and the like.

Also has feature if getting lots of sun in sunny fife, can go completely off grid through the night, need to remember to go on grid when daylight happens, so can export....

I have now had a new inverter and 3 Ion batteries installed so another £3.650 plus maintenance package which now gives me 10 years full cover parts and labour, so a lot of money

[@GaryDoesSolar]

Hi Martyn, sorry to hear you had to shell out another few thousand pounds just to keep your system going. This is the downside of having a string inverter (which is the most popular option for domestic solar) - they just don't last much more than 10 years (best scenario) and could fail a lot earlier (as it did in your case). And you were hit with the next problem, where DC-coupled batteries compatible with one string inverter are not for other inverters - such a shame, but maybe you can sell them...

Nice simple video. I need a new house roof so, as an electrical engineering person, I have just spent 2 solid weeks mining through all the permutations of an in roof system and max out on surface area, inverters, optimisers, panels and batteries all with similar but not identical features. There are a lot of choices (too many) some better than others but software compatibility and support should not be overlooked as I see many complaints about "this stopped working or updating" needed software update etc etc and this can be overwhelming for someone who is not technically competent. Not convinced of battery way just yet, but UK Govt incentive to reduce VAT to 0% for a complete installed system should be taken advantage of. Payback under current tariffs is about 8yrs but if prices go back to 1yr it becomes less attractive. ...but I need a new roof so it comes at about 25% more than re-tiling. So Im looking to recoup 25% of an outlay which makes solar a no brainer.

This one was designed to just be an easy introduction, and I'll get deeper into the topic and all the complexities with future videos (whilst still hopefully explaining things well!) I can see you've got in quite deep already! I agree, unless you buy a ready-packaged solution like Tesla Powerwall (which, even then, has its own notables/issues) then you're in a world not too dissimilar to building your own PC - lol - what do you do when the component parts decide not to play nicely with each other and the installer doesn't want to know anymore?? Aside from that, you're definitely in a great position, having to deal with the roof anyway; essentially killing two birds with one stone.

@@wajopek2679 when we wanted to add additional panels on a second roof to complement our existing 3kw system we asked for quotes from 6 suppliers, two didn’t even come back to us, two were discarded because with one I had more idea about pv than the sales person, the other quoted for more panels than could have been fitted to the roof. The other two were very close and ai chose one that said correctly that as our proposed new array would take us over 3.6kw production we would need further DNO approval. That was in 2020 and given the recent explosion of interest in pv because of energy prices and delays in supply of materials getting a decent knowledgeable is now even more difficult. That said after doing the research, the resulting finished product does make a massive difference to your electricity bill. Good luck and I hope you find a decent installer soon. Adding a Tesla Powerwall and the extra 1.3 kw array allowed us to cut our mains use by a thrift. It would have been more but we swapped our plug-in hybrid for a full electric bev.

Hello Gary. thanks for another informative video. I'm just starting my solar research & i've not found many videos dealing with 3phase residential supply. Can you maybe do a video regarding 3phase set ups? What is the better option 3x single phase inverters or a single 3 phase inverter? Do you split the solar array per phase or split the total array power across the individual phases? Have you done a review on the Canadian Solar EP Cube system? thanks alot. Ian

Thanks Ian - glad you're getting something from my videos. Now, I don't have any experience with 3-phase unfortunately, so can't be of much help :-(

[@Croi_Fiain]

Like others commenting here, I have only recently started wading through research to work out what may be best for me and have watched and read so much on this. Your explanations are great, very simple for a newbie to understand so I look forward to more. One piece of information missing from every single video and article I have seen, however, is... How do you connect the solar system to the electricity supply in the house so your appliances use the electricity generated by the panels? So, for example, on a simple system you have the panel -> inverter -> house. How does the inverter connect to the house supply? I'm new and trying to self-learn everything electricity... Does it just plug in to a mains socket? Does the system have to be wired in to the domestic consumer unit (ie fuse panel) and therefore need a qualified electrician install? Something else? I may be asking the wrong question, or the right question poorly 😂

[@GaryDoesSolar]

Hi there Croi - thank you for the kind words on my videos! Now you raise a very good question and one that I wondered myself in the early days. It turns out that A/C electricity and the national grid system is a wonderful concept and happens to be pretty versatile. Fundamentally, power stations of all kinds place power onto three wires (3-phase electricity) and these three wires are fed to homes all over the country. Each home is typically fed with any two of these wires (single phase) and you can have as many consumer appliances as you like attached to those two wires in order to draw power. The really cool thing is that this is not just a one-way process. If you have your own power generator (e.g. solar panels) you can place power yourself onto the two wires coming into your house, and that power will either be immediately consumed by appliances in your house, or 'exported' out back to the grid. This is the magic of the inverter - it is connected directly to your incoming supply (those two wires) via the consumer unit. All the inverter has to do is convert the DC voltage of the panels into AC, and it does that by generating a sine-wave of the correct voltage and more importantly, the correct phase of the AC already on the two wires. If you want to get really technical, the phase has to be slightly ahead of the phase already on the wires so that power is essentially pushed onto it. Ok, that was the long answer; the short version is that you simply connect the inverter into your consumer unit :-) Hope that helps!

[@Croi_Fiain]

@@GaryDoesSolar Brilliant! 👏🏻 You could, if you were so inclined and had the time, create a course with explanations like that 👍🏻

[@GaryDoesSolar]

Haha - ok, I'll consider this as a topic for a future video :-)

[@michaelblackmore883]

Hi Gary, Given the current projections for electricity costs and inflation have you changed your position. My inclination is to go ahead and take advantage of the current Octopus Flux tariff while export prices remain high. Of course one worry is that if a lot of new installations start exporting to the grid it could become overloaded and the tariffs could be drastically reduced. One would need a much bigger battery bank to offset this. Mike

[@GaryDoesSolar]

Hi Mike, so inflation is always a tricky factor to manage, especially as it has been so high lately. For example, one of looking at it, would be a financial investment of say £10,000 two years ago, would cost you maybe £11,500 today for the same installation (assuming nothing else happening in the market to reduce costs). One could argue that taking a loan now would be preferable than waiting another 2 years when inflation will increase those costs further, but of course the cost of those loans is more expensive anyway. So, personally, I prefer to look at inflation as "what things cost today" then forget about it. Discounting inflation then, if I look at the market, I see that electricity prices are falling, but falling very slowly and they're still more than double what they were 3 years ago in the UK. Export rates are high, and many people are certainly benefiting from exporting all the solar they cannot use (and in the summer, that can be a lot! In my own case, I'm currently exporting 300-400kWh every month on Flux). I'm also hearing that equipment prices are starting to come down - essentially losing the premium they had from a market where demand totally outstripped supply. This, combined with the fact that there are more installers in the market now, and many more trained engineers to carry out solar installations, it is starting to bring the labour costs down too. So, in summary, I don't think my position has changed - but every person needs to look at their own situation and requirements very carefully, spend a good amount of time looking at the numbers, obtain at least 2 (ideally 3) quotations based on the same equipment requirement (otherwise you can't compare) then hopefully take the plunge! :-) Finally, you're right - as more and more residential properties export to the grid, unless the DNOs prepare for this, it'll cause bottlenecks. But, you know that's the game you're in if you're a DNO, so I'm expecting them to be getting on sorting out s strategy - because this train ain't stopping...

Hi Jag, thanks for the great feedback! And yes, in the spreadsheet you can simply substitute new values in columns N and R for the tariff you're interested.

Also remember your inverter plays a huge part. If you are fitted with 3.68kw inverter if your home goes above this i.e using a washer, dryer, along with normal base load you will most likely go above the 3.68kw meaning you’ll draw usage from your battery or grid. Not many installers explain this to customers.

[@GaryDoesSolar]

Great point, Dan. In my next video, I’m covering all the equipment needed to go Solar. I’ll make mention of what you say - so easy to overlook when choosing a system! 🙏

Hi Gary - great stuff. Just made the move myself (1 week ago) and am now keenly watching the sun and the app to see how the system is performing. I will be linking to an air source heat pump in a few more weeks as well. We are doing some building work so this seemed like the time to make the leap.....the energy price hike came a bit later than the decision but just made us feel we did the right thing. Happy to share more detail with you should you wish. One point for your subscribers is to watch out locally for initiatives from buying groups aiming to get the price down. Up here in sunny Suffolk the local council launched "solar together" the aim of which was to help get the investment down by getting people into a group and going out to tender....sound familiar?! Seemed to work though - pricing was pretty good. Watch out for the flyers or emails from the council. Rgds Stephen

[@GaryDoesSolar]

Sounds great, Stephen! Yes please - can you share more detail? I've heard mixed responses about ASHPs - but I guess if fitted in conjunction with solar, they make sense, given the electricity requirement. Did you also look at ground-source? Was that an option for you?

[@stephenlongbottom9391]

@@GaryDoesSolar yes understood ASHP was a bit of a gamble, but decided after some reading and some discussion to go for it due to the link with solar and using the energy in conjunction with battery(s). I did think of ground source but taking into account, time, cost etc went for Air. I cant remember now if there was the grant on ground source(?)...there is grant on ASHP (£5K) It will be interesting to see how the two work together and of course i will let you know. We cut off the gas on Monday - so we are half off the grid and now its a question of getting the usage of the energy correct - balance with sunshine/appliances/battery etc etc. I havent received my details for selling energy back to the grid as yet (can you believe it could take 8 weeks!)but I checked with Octopus (for the record - I think they are the best utility I have used) and with the tarrif I am on (agile) I am told I can get 7.5p for a unit sold back.

One more point looking below at some points - we are pretty well South facing and shade is not heavy.

The only reason the payback is not so good for fewer people in the house is the relatively high cost of the diverter and installation against the level of savings that one or two people can achieve.

Thank you for the very informative video. One question - if you have a solar & battery system and your Hybrid inverter is rated less than the peak output of the system, and is therefore clipping, are you able to divert the "clipped" energy into the battery? Salesman says you can, but I'm sceptical.

[@GaryDoesSolar]

Hi Andrew, thanks for the kind words. Yes, you generally can if the battery is DC-coupled. Check with the data sheet of the battery in question. The clipped power can never leave the inverter onto the AC supply but it can be fed directly into the battery 👍🏻 A nice benefit of DC-coupled batteries 😀

[@jamesan2517]

I wonder how much energy is required to make one solar panel. So, if energy is going up then, surely the price, to make a solar panel, will go up accordingly. If you live in an area that has less than 50% sunshine, all year round, and solar panels are only 20% efficient, that seems to me quite a low, overall total efficiency. If these panels are produced outside of the UK then, with fuel cost increasing this will also add to the cost of transport. So, those properties that are not yet fitted with solar panels, (4kW to 6kW typical) would be paying quite a sum for a complete system installation. As you mentioned, the possibility of energy prices are set to rise further then payback may never be reached.

[@GaryDoesSolar]

My next video covers how to calculate the payback period, which might be useful to you. I think energy prices, although rising sharply at the moment will fall back to 2019 levels within 5-10 years because most of the generation by then will be solar/wind which is 10 times less expensive than fossil fuels are. Would you agree?

[@dc1544]

Ground mount solar is also a huge option.

Agreed, if you've got the space for it. Not many people have though. I really like the idea of car parks being used to house solar - great use of otherwise wasted space, and gets the rain and sun off the cars.

Hi Gary. Great presentation. However in your simple model changing an EV, it normally takes a minimum of 7kW to charge an EV on a Single Phase System.

[@GaryDoesSolar]

Hi Campbell - thanks for the kind words on the video 👍🏻 On your EV charging point, i based my commentary on the Zappi charger in “eco” mode, which will charge a vehicle with whatever Solar there is, limiting as far as possible any draw from the grid. There may well also be a minimum charge rate of say 1.4kW. Perhaps someone can confirm as I don’t have an EV myself?

[@AdrianMcDaid]

Can charge mine from 1.5kw on zappi charger. So I try never send power to the grid.

[@edc1569]

I have watch so many videos & read so much and am still of the mind that not only is solar overpriced but that it is STILL NOT worth having unless you know you are staying put for many, many years.

Yeah, a solar and battery installation is most definitely a considered purchase for anyone. And unless you plan to stay in the same property for 10-15 (or more) years, there is a chance that you'll lose part of that investment. But, I'd argue that in a property sale, the solar and battery installation would have a clear monetary value, evidenced by reduced bills over the years.

Fantastic video. Really like the graphics. I have heard micro inverters are better on each panel than one inverter. Any thoughts? I find the buying solar experience very complex.

We've just bought a house which is North/South facing, so I'm starting to wonder whether the ROI on solar is starting to become attractive, also considering things like air-source or ground-source heating and perhaps even some wind power to help go off-grid a little more (lets face it, wind is more likely to be readily available in the UK that sun!). Wind turbines are a little unsightly that's the downside.

[@GaryDoesSolar]

Yeah, a combination of solar and wind in the UK (and perhaps many other countries) seems to be a good mix. I agree, traditional turbines look unsightly - especially in an urban environment. I see there are some newer vertical turbines available, that are much more aesthetic and supposedly quieter? But what about the costs? I'm hearing turbines are not so cheap...

Hi Gary. Thanks for this excellent explanation and easy to follow video. I may have missed it, but is your estimation of pay back period applies to solar only or solar with a storage battery? My local installer says there is a huge waiting time for Tesla powerwall and may only be available beginning of next year. So I may decide to go for the solar panels only for now, but I would miss out on the 20% vat rebate. Unless I consider another battery storage, but I quite the sleekness and simplicity of the Tesla.

[@GaryDoesSolar]

Hi G LSC, thanks for the kind words. I'll try to keep this up with future videos! :-) Now, you raise a great point regarding batteries and return on investment. For solar panels only, you can certainly expect a payback of 5 years (or less) in the current climate. For batteries though, the business case is harder, not least because of the relative cost and the limited lifespan of the battery (maybe as low as 7-10 years). My estimations in this video were based on a combination of solar and battery, and it's the battery element that pushes out the payback period. That's not to say that batteries are not worth it - they are, but the *relative* return is lower than for just solar panels. One might ask, if I'm getting a great return with just panels, why water that down by adding a battery? The answer might come down to more than the money case, but also the freedom case - the freedom to use electricity when you want, rather than trying to get all the washing done while the sun is out etc. Regarding the Tesla Powerwall, I'm in exactly the same position as you. I like the way Tesla is approaching the problem and I think their technology will typically always be ahead of the competition (not least because of the immense R&D budget Tesla has). But Powerwalls are expensive and hard to get. And by the time you get a PW2, the PW3 will be out, and you may have wished you'd waited for that... So, my own strategy is to start with Pylontech batteries, which being modular, will allow me to add further capacity over time to suit my needs (and generally allow me to learn about how the technology works out in practice). Then, maybe in a year or two's time, once the market supply issues have been solved and PW3 has been released with all bugs ironed out, I'll likely buy one of those, and simply sell the Pylontech batteries (even used units will likely always be in demand). I'll then have a battery solution that will just take care of itself going forward (as my interest in day-to-day management will no doubt have waned by then). Hope this helps!

[@GaryDoesSolar]

I forgot to address the 0% VAT point. It's great that the UK gov has zero-rated VAT on solar purchases, but they should also allow people to make staged investments as not everyone has the capital to get everything in one go, nor may they wish to even if they did. I can see the VAT scheme being changed accordingly in the next year or two.

A friend of mine has recently had a solar system installed, and I think the installers have done something 'odd' and would like to ask your opinion. His installation is this: 22 longi 550W panels. 10KW 3 phase Deye inverter. 4 x 10KW LV Sun batteries. Prior to his installation, he had 2 consumer breaker boxes with 12 circuits per box.....so a total of 24 circuits. After the installation, the solar company had added a 3rd breaker box (with 12 breakers) below the other 2 boxes and marked it as 'Backup'. 12 Circuits from the 2 original breaker boxes (6 from each) were moved to the new, 'Backup' breaker box. Tonight, he lost grid power (thunderstorm) and only the circuits from the 'Backup' breaker box worked (from the batteries I'm assuming). A couple of questions: 1) I had assumed the inverter would supply 'all' circuits (via battery) should the grid fail. 2) If the above is true, why would the solar company install and move circuits to another breaker box that seemingly is only powered by the batteries.

[@lhffan]

I will install solar to remove all of my bills.

[@GaryDoesSolar]

Great to hear! You may not be able to cover ALL the bills over winter, but for the rest of the year, you should be in good shape to wipe most of them out 👍🏻

[@gingerninja7187]

It’s a real shame that there isn’t more help with renewable energy, the government offer £5000 towards a heat pump , why not offer that money towards solar ,etc ,

[@GaryDoesSolar]

I totally agree. I have a fried in Spain who received financial support (rebates) not from the Spanish government and also the EU! The UK has removed the VAT (20%) but really, they could do a lot more. It just needs some forward thinking. Hopefully the newly formed government (under Rishi Sunak) will make the right decisions on future energy...

[@andyhello23]

Shame such systems are too expensive for most of us.

[@GaryDoesSolar]

Hi agree, Andy. I'm hoping that things will calm down over the next 12 months, so that solar becomes a bit more accessible to more people. Of course, it was always be a sizeable investment, but hopefully the payback (and therefore the risk to capital) is manageable.

In the winter , totally useless, my hydro bill is 1/2 of solar cost per year, no worries about warranty, maintenance, no up front expenses.

[@GaryDoesSolar]

Sounds like you're in a very good situation, energy-wise, well done. However, the vast majority of people in the UK don't have access to a water source to generate hydro, but they are likely to have access to solar. Now, whilst solar generation in the winter months is low, for 8-9 months of the year, it is possible with solar to cover near all of the electricity costs. And in the winter, a battery can dramatically offset costs usage cheap overnight rates. My videos are here to help the majority save money.

[@jackrainbow560]

As a social tenant I am not allowed to install solar myself even though I would pay cash in advance. Is that fair and reasonable?

[@GaryDoesSolar]

Sorry that you're not being given permission to install solar. It might not seem fair, but the property owner may want to keep things simple, not wishing to add extra burden.

[@fractalmadness9253]

I just realized I was paying 1st world energy prices on a 3rd world salary.

[@GaryDoesSolar]

Huh?

[@1701_FyldeFlyer]

Im tempted by solar and battery but the cost is truely eye watering, 12 grand for a 5kw system and 3 or 4kw battery?! Everyone knows when the government makes installation vat free, the installers just inflate their prices by 20% and the customer doesnt see any real reduction in price. Many people seem to have issues with the inverters packing up every 5 tears or so and costing nigh on a grand at current prices, are a further cost. There's also the cowboy factor so, if getting the more reputable suppliers, you end up waiting forever because they're fully booked. As for selling excess back to the grid at no more than 3 or 4 PENCE, someone is having a laugh.

[@GaryDoesSolar]

I don't dispute anything you say here. And this is always the problem with any market where demand greatly outstrips supply. I don't know what the solution is, but I definitely see a role for government in making sure all actors play fair. For your situation, I recommend you join a solar forum, like this one, where you can learn a lot and also check to see if the quotes you are getting are fair and reasonable: facebook.com/groups/2197329430289466
