How to Choose SOLAR Wisely and Avoid Costly Mistakes

[@GaryDoesSolar]

* NOTES SINCE PUBLICATION * 1. In the video I make reference to MCS, a certification scheme, normally required by energy providers before they can provide certain services like paid export. There are now other similar schemes, including FlexOrb that energy providers are accepting as well. Competition in this area is good as it will help keep the pricing of these schemes down. 2. Also in the video, I talk about the effect of shading on a single panel affecting all the other panels. In actual fact, it depends of the type of shading. If the shading is hard (for example, from a chimney or another building) then the panel is able to protect itself (via bypass diodes) without affecting any the other panels in the string. If the shading is diffuse or limited (for example, a TV antenna or cable) then this could well affect the other panels because that kind of shading is not sufficient to activate the bypass diodes in that panel. See this video for a more complete explanation: kzbin.info/www/bejne/b3jZmXeeeLh9ndE

One of the companies I priced for Solar panels was $65,000 for my home, It would take me 36 years to pay for that at the cost of what I pay for my light bill now.

[@AnthonyAlvarado78]

​@docbrown6550 most states have rebates and SRECs available to reduce that burden. Most of my analysis came back at a 5 year pay for itself cost.

[@docbrown6550]

@@AnthonyAlvarado78 My light bill is around $100 a month, at a cost of $65,000, it is not feasible in any form or fashion to buy solar. Our state does not help that much to make enough of a difference. It would actually take me more than 36 years to pay that off, at the cost of what I'm paying now for my light bill.

[@elonslawsuit5004]

Gary, being in the process of "going solar" and getting quotes, I've found your video most helpful in some respects so great thanks for that. I think I prefer the idea of microinverters with an AC coupled battery (despite the potential power losses), i'm not sure the price difference from a string inverter is so pronounced anymore, particularly a string inverter with optimizers and most microinverters have a 25 year guarantee nowadays (Enphase) versus a string inverters 10 year to allay fears of inaccessible repairs. I presume this means peak power usage (without grid) is limited to ARRAY + BATTERY in daytime and BATTERY alone in the evenings. I noted the batteries in my quotes, (Give Energy, Solax, Alpha Smile B3) only have a maximum charge/discharge rate of 2.68 Kw. If my house is using (TV-300, Microwave-1000, Fridge-200, WIne Cooler-100, Lights - 150, PC-150) and I put the kettle on at 3000, will that switch seamlessly to drawing from the grid or am I likely to experience difficulties with appliances? I suspect I may be getting mixed up with off grid systems there? Do you see that level of battery discharge rate as a problem if one is desperate to not draw from the grid if possible? Are discharge rates of that magnitude standard across the industry or can you get larger, in general those figures don't appear to be a readily available from an internet search although I can find Tesla Powewall is 5Kw surging to 7.5Kw? I suspect I will be more conscious of using other high power appliances during daytime if possible but I do enjoy a cup of tea in the evening! Thanks again.

[@GaryDoesSolar]

You'll find that your solar and battery system will seamlessly provide electricity to your appliances both with and without any grid requirement. And I don't know if you read about the latest Tesla Powerwall 3, but it's got a 11kW discharge rate, so no worries (at all) You'll be able to have that cup of tea and not draw anything from the grid :-)

[@elonslawsuit5004]

I have Gary and it has a lovely £11,500 price tag and a waiting list over a year long when it eventually gets here so I'm priced right out of that one. I'm thinking about 2 x SolaX 5.8 LFP offering, I believe I've read that their lower end power output is increased if 2 batteries are wired in series together as master and slave but not sure if that's true, do you know?@@GaryDoesSolar

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 never has a 'pay-off' from grid suppliers & is only Renting your Energy forever!! In contrast, Your own PV system is Owning the energy Source so it Has a payback🌅🗽

[@johnscamera]

Really useful, and wish I had taken two different approaches when I accepted the design of my solar installation: 1. As you say, educate yourself, then get comparative quotes for the same configuration; and 2. start with desired payback period and then work backwards to select the design best suited to the design constraints. I got lucky with the second one, but got caught out on the first one as I have 3-phase supply to the home. Design would have been different if I'd known how the components worked in multiple phases. A video about multiphase installations certainly would have been useful!

[@GaryDoesSolar]

Hi John, it's a tricky one eh? Just how much research should one do before taking the plunge? That's one of the reasons I starting making these videos, actually - to save people time, and to show that there is quite a bit to think about before buying an installation. It might be that you will change your setup over time, and so you can incorporate some of the benefits with 3-phase at that time - good luck! :-)

[@barry28907]

Thanks Gary. I'd like to point out one possibly helpful option -- at least here in the US. I used a Solar Co-op -- specifically Solar United Neighbors. They assembled a group of about 50 potential buyers in my city and put out a standardized RFP. We received 6 bids, which our selection committee reviewed in detail. Each installer quotes a sort of 'menu' panel/inverter/battery options, plus a schedule of possible additions (eg: long wire runs, warranty enhancements, etc). It even got into the weeds on such topics as diversity in hiring practices and community philanthropy. We had two experts from the Co-op help us evaluate the bids. It was a VERY informative process for those of us who volunteered for the selection committee. The selected vendor then visited each group member and prepared a custom proposal. The co-op experts checked the proposals to ensure that they conformed to the agreed group pricing and terms. The approach might not result in the absolute rock-bottom deal, but I think it's probably a better deal than 95% of us would have negotiated individually. And each group member is completely free to back out at any time before they sign their individual contract. Those that walked away did so with the group's negotiated price menu in hand.

[@federicov362]

A little correction, microinverters should not be the more expensive option, it should be the same as a system that use optimizers, let says is buy a 10kw String inverter for £2.000 (SolarEdge) and you install 27 panels (370w each) for a 9,9kW system array, when you divide 2.000/27= $75, then an optimizer will cost you around $60 (or more) each, the total is around £135+ per panel, which is very similar to a microinverter like Enphase IQ7A, £160 each (and now cheaper with the new IQ8 series). This is just an example, the String Inverter + Optimizers is more expensive when you install a smaller array system, because a 5kW won't cost you half price of a 10kW S. Inverter, so the cost per panel is a little higher, and keep in mind when you use that setup, you have 3 points of failure (panel/optimizer/inverter), while with a microinverter you only have 2, besides Enphase provide a 25 years of warranty.

I got a 55w panel on my east facing balkony. And, well it seems worth the price. Even with the ecoflow rover solar generator included. For the current price of electricity here. I may save its worth in a couple years already for the hours i get. In scandinavian summer where the sun never sets. Does not work in the evening. What i measured from the panel is under one amp of current, so two panels might get it to charge with that. I need to find proper places for the panels before i get another, so not happening too soon. Has definitely been worth it for the exitement. I got it mainly out of interest rather than economics, but yea it sort of makes sense moneywise too. Plus. The ecoflow is just about enough to keep my fridge running through a night of outage. Haven't tested that though, may need more startup watts..

Great video again, Gary. Something I've found when shopping for quotes is that MCS is now rivalled by FlexiOrb accreditation. They are the same standards, but I've been told by an installer that FlexiOrb charge an annual rate compared to MCS charging per install, so some installers prefer one over the other depending on volume. Not sure of the details on that as it's just what I've heard from a FlexiOrb-accredited installer. Perhaps unsurprisingly, all the MCS-accredited ones I've spoken to insist that MCS is the only accreditation worth anything. Crucially, Energy suppliers such as Octopus, British Gas, EON, Scottish Power, OVO and UW are now accepting FlexiOrb accreditation for SEG tariffs. Might be worth an update to the description, or even a short video explaining the new accreditation and certification standards. Cheers!

[@GaryDoesSolar]

Thanks - this is a good point. And a welcome situation because it’s typically always detrimental to the consumer if there is a gate controlled by a single supplier (in this case, MCS). Competition drives better quality and price.

(And plastic ones now verboten on upgrades (even though 90% of us have them) - where can and can't the equipment (inverter, battery etc) be located- my garage is detached and too far away) - can solar set-ups be put on out-buildings and 'piped back' into the house ?

Mine are discontinued 250w panels at 15.4% efficiency. Not great now but good at the time. Still, they'll last another 15 years so not worth changing them. Great advice on how to spot a dependable EV installer. I need one for support as my inverter is nearing the end of its expected life and my accredited supplier told me about the optimisers now available. They weren't included in my setup so I'm having them retrofitted. At least I now know, independently what they're for and how they work.

Totally agree, and I’m thinking that with energy now being on the forefront of everyone’s (including the government’s) mind, we can expect to see some positive changes in policy 👍🏻

[@remaincalm2]

From one Gary to another, thank you so much for your impartial and clear advice. I thought I knew enough but I quickly discovered that wasn't the case! Your advice at the end about choosing an installer is top notch, all very valuable tips. I consume 20,000 kWh per year but no more than 20 panels can fit on my roof, so only 25% of the daily demand can be met by solar during the summer months. Less than 10% can be met during the winter months. Solar does seem rather pathetic in this light (pun!) but I don't know what else to do given that the Oct 2022 price increase will shove my bill up to £9K per year which pushes me closer into the growing "heat or eat" group.

[@GaryDoesSolar]

Hi Gary, there are not enough of us Gary’s 🤣 Wow - 20MWh per annum! That’s about 3x my own use. Ok, so for my own (impending) installation, I’m looking at 19 x 400W panels and 2x9.5kWh batteries. This should cover my daily use of between 10-30kWh (the days with higher usage is mainly washing machines and tumble dryers - which could be load shifted). I’m building a spreadsheet for my next video which allows you try out various solar/battery configurations. I’m not sure it can solve your situation, but I’d be more than happy to send you a copy in advance for you to play around with? Just let me know…

[@kpsitwala1]

Great video, after checking hundreds on them, well laid out with clear understandable information, please make more videos with info on your installation if you have one and how much electricity is generated from Nov to feb in uk thank you.

Thanks for the kind words. My own solar journey has been a nightmare. All being well, it’ll be installed in January. I’ll maybe make a video about it 👍🏻

[@gingerninja7187]

Your videos are brilliant, so detailed, I believe ,after watching anything that people are unsure of are definitely made a lot clearer, your knowledge is priceless, you should start up your own solar company, you have the know how , you just need to employ people to install that With reference to quotes I’ve had a few and except for one ,they seem to quote for 4kw ,I suspect it’s because it’s the easiest option

[@GaryDoesSolar]

Hiya. Thanks for the very kind words. My main activities are in mobile space, would love to have more time so I could get more involved in the energy sector, as it's such an interesting space! If you're in the UK, then the 4kW quotes are a lot easier for installers as they only require G98 certification, which is far easier to complete than G99...

[@kenmaher3388]

Clear and concise, thank you for making this very useful video. At least now I know what are the important questions to ask when getting a quotation.

[@GaryDoesSolar]

Hi Ken, you're most welcome. Happy to help you out! :-)

[@wajopek2679]

For this 2nd "Primer Video" you have indeed covered the major basic points which took me about 5 days to learn from scratch. Budget will always govern most installations (but shouldn't) as in my case, the front of my house is SW facing so I have 3 roof areas pointing in different directions all with clear views and good sunlight in morning/ afternoon/ evening that can be used (I'm changing my roof so going for in-roof system) and that puts me into optimised/ micro inverter category. Jury is still out on having a battery due to space (pointless having a small one) and Im not having it on view outside as thieves can easily isolate and steal them.

[@GaryDoesSolar]

Great to hear that I’m covering the right topics 😀 your house situation does sound like a challenge, but from what you’re saying, you’ve got a promising solution! In-roof Solar sounds like a good plan - I think I’d probably do the same, but I’ve got quite a few velux windows to skirt around. I totally agree with you on the battery front - the biggest you can afford is likely the best way, and installing it inside the house would certainly not give any passer by reason to steal it! Hope all goes well with your setup, and if there are any topics you’d like me to consider for future videos, just let me know 👍🏻

[@computerbob06]

I'm thinking about putting my battery (if I get one) in the unused chimney! I live in a Victorian terraced house so no real space to use but both chimneys are not used and the batteries are IP certified so should be fine in the chimney! Hopefully?

[@janeco4732]

Hello Gary, thank you for such a clear video. Until I discovered it I had been floundering around in the dark. I recently 'expressed an interest in a local authority group buying scheme. The winning bid by the solar/battery provider will be the cheapest I suspect. My concern with this is that I would have limited input in what they want to supply to me (solar panels/inverter/battery). You have given me some idea of how to consider whether their offering is right for me. Exactly what I needed at the right time.

[@GaryDoesSolar]

My pleasure, Jane - very happy to have helped you 😀 and all the best with your solar journey 👍🏻

[@cjkenning]

This is awesome. So much information that no one else seems to know/share on their channels!

[@GaryDoesSolar]

Thank you - that means a lot to me!

[@mattcole6230]

Great video. One question though and not covered is the integration of battery storage in a grid tied existing system on a FIT. I imagine an AC coupled inverter is the only choice unless the existing string inverter is swapped out for a hybrid and then, metering will need to be checked so as not to effect the FIT readings.

[@GaryDoesSolar]

Now, I don't have a FiT setup myself, so I'm only going on what I've heard from others. My understanding is that so long as you don't alter your FiT setup (e.g. do not swap out your inverter for another), then provided to you inform the FiT scheme of the changes (specifically only additions) you're making to your home, everything should be fine. For example, you can add a battery, but it must be AC-coupled with it's own inverter (built-in or otherwise). You can also add more panels, but they must be on a separate inverter to the existing panels.

[@StephenWalker42]

Thanks, Gary, really informative, we are just starting to gather the information we have a flat roof above our flats with E7 off-peak heating supply, so are looking at solar supply in the day and E7 charge of batteries at night. Thanks for your channel you have a great presentation and keep it simple.

[@GaryDoesSolar]

Hi Stephen, thanks very much for your kind words - and I wish you the best with your solar/battery plans. I do like the fact that Economy 7 tariffs are coming back into fashion. If you're wish Octopus, you might also want to look at their new Flux tariff - I'm creating a video on that tariff at the moment...

[@nigelhamilton-brown1918]

Thanks for the video, to clarify: so a 410w rated panel with 22.2% efficiency only produces 22.2% of 410 watts? i.e. 91 watts?, thank you

[@GaryDoesSolar]

Hi Nigel, you're most welcome. You'll be pleased to hear that for the panel you describe, on a sunny day, facing the right direction, it will generate 410 watts of power. The efficiency rating is a measure of that power against the theoretical maximum power than the sun is supplying: earthobservatory.nasa.gov/features/EnergyBalance/page2.php

Hi Gary, with regards to the simple dc string inverter system. Don’t newer panels have built in diodes that will reduce the panels output without reducing the output of the other panels? Thanks.

Hi Gary. Like many I imagine, I am new to solar prompted by the expected increase in electricity and gas bills. I've watched umpteen videos and read tens of thousands of words. I could have saved myself loads of time and effort and just watched your videos instead. They provide clarity in the midst of confusion. Many thanks for taking the time to do this.

Hi Gordon, you're very welcome! This was my aim, so it's great to get feedback like this :-)

[@andyxox4168]

Do you have any opinions on vertical, wall mounted panels. The installation is much easier and easily a DIY project and output doesn’t seem to be too compromised …?

Hi Andy, this is not something I have much experience about, unfortunately. but I have seen a couple of KZbin videos, where people have installed such, including these ones: kzbin.info?search_query=wall+solar+panels

[@craigbutler6243]

Comprehensive video. Regarding shading at the13.00 minute mark, there was no mention of module internal by pass diodes that help elevate power loss when shading occurs. This is an adequate solution more often than not so it is not always necessary to install optimisers to solve shading issues. Well presented video Gary, very good.

[@GaryDoesSolar]

Hi Craig, thanks very much for the kind words. And yes - a good spot! As it happened, I wasn't aware of bypass diodes when I made the video. I thought I should investigate deeply when I had some comments about the claims of the optimiser/microinverter manufacturers. This resulted in a dedicated video on shading.

[@JavedAkram-j7o]

Thanks Gary for your excellent videos they are very informative. In deciding on an AC or DC storage battery. The more conversions the more loss. If you have micro inverters on your solar panels isn’t that converting your dc to ac. Therefore can’t that go to an ac storage battery without conversion. If this is the case why do we need an inverter separately if the micro inverters are your inverter. Trying to decide what type of battery to get and watched most of your videos. Thanks for your help.

[@GaryDoesSolar]

You're very welcome! Now, with a microinverter installation, your only option is for an AC-coupled battery solution. Yes, there are greater losses than a DC-coupled equivalent, but really, I wouldn't worry. In all the modelling I've carried out, it really doesn't make a lot of difference to the final results. I'll be saying more about this in a follow-up video I'm making on batteries...

[@harryhaines1995]

Gary! What a sensational video, love seeing a thought leader break down solar and explain it as if we were all 5 years old. This is the exact type of content that needs to be readily available before people decide to invest in solar. I would love to hear your thoughts on some brand-new software we've just created. Gary, could you reach out to me as I have an opportunity for you which I think you'll be very excited about.

Thank you for producing an excellent video which I found to be very clear and simple to understand. Like many others I am starting to think seriously about installing solar and your explanations have given me a basic grasp of the components used, their functions and various options. It will also enable me to have some rather more informed discussions with potential installers.

[@GaryDoesSolar]

Thank you so much for this feedback, John. My next video on calculating the payback period should be ready in a week or so. Hope you enjoy!

[@dadiazor]

Really thank you for your videos Gary, and all the work you've done trying to make PV energy reachable for everyone! I have a question about when you mentioned DC coupled batteries may not be suitable for backup supply. What exact function on the inverter decides that? In my understanding, if the battery can function while on-grid, it also should be able to function off-grid...

[@GaryDoesSolar]

Your kind words regarding my videos are very much appreciated - thank you! :-) Agreed - the principle is sound. I think it might simply be that not all string inverters have EPS capability built-in. Personally, I have a GivEnergy inverter connected to two DC-coupled batteries. My installer has wired them up in automatic EPS mode, where if the grid supply goes down, the inverter is able to power certain home appliances through a dedicated consumer unit.

[@rupertmiller4718]

Really useful video. What is apparent is that a large part of the cost involved is not related to physical equipment but to istallation costs and the overheads and marketing costs of the installing company. Then there are certification costs if you want the system to be connected to the grid. I have been thinking about an alternative route; a DIY installation with no export to the grid.The only bit I haven't got my head around is connecting to the house that isn't Heath Robinson!! My House faces East West but I have a south facing shed and will soon have a carport with similar orientation and reckon between them they would support an array of about 4KW. DIY would cut the cost by around 40% or more. Even more if I built the battery myself.

I wish I had seen your videos back then. We had no explanation of how our system worked and how to maximise our use of it, so haven't really been using it well. We've also had a few blips - mostly with the Solar I-boost diverter - and found it stupidly hard to find help. Thanks for your empowering and professional video.
