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.

That's not true anymore. Modern technology limits it to the one panel

Gary, Thank you so much for this video, I'm just starting on the solar/battery storage learning trail and I found this video remarkably comprehensive in explaining in, laymans terms, many of the questions I needed answered and the most surprising thing of all was I was expecting to find at the end of the video some sort of promotion for this or that particular equipment or that you were an installer, but no, just putting this info out there without looking for anything in return, quite a revelation in todays society, so again many thanks for your time and effort. best regards

[@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! :-)

[@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

[@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.

[@GaryDoesSolar]

Hi Federico, thanks for the extra analysis. Great to see that microinverters fare better against other solutions than I thought :-)

It's great to have such a detailed explanation of what I have had running all this time and interesting to see how the hardware has changed over the years. 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.

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.

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 👍🏻

Well worth a watch and has given me some use full tips I am struggling to find a decent solar installer plenty of people who'll txt me a price but nothing in righting and other companies just turn up and no quotation, seems to me its a mine field just trying to find an installer. when I do ill refer to your video.

[@GaryDoesSolar]

Thanks Bob - yeah, because a lot of people are trying to get solar installed, demand is very high against the number of installers available. This situation might exist for another year or so before things calm down, unfortunately. Hope you are able to find a good installer soon!

Very good, simple content that almost anyone can follow. Well done

Thanks Marlon 🙏

Thanks Gary I’m looking and you’ve given me so much info…always say INFORMATION IS KEY…nothing worse than looking for something and not knowing a bit info and being pushed into buying what you don’t want or need ..

[@GaryDoesSolar]

Hi Darren, thanks for the great feedback. I totally agree with you and hope my videos are 100% information, 0% filler 😀

[@darrenwilkinson4348]

I’m really surprised that there hasn’t been more talk of this on the tv..and I know you can get grants if your on some sort of benefits unlike most people out there .. But there needs to be a option or insensitive for working people ..

[@GaryDoesSolar]

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 👍🏻

[@troopersmart]

Great video Gary! Great to see you are still explaining complex things in a straight forward way! I've been on the solar journey for 2 years now and still learning!

[@GaryDoesSolar]

Hey Mark! You found me on KZbin! Who'd have thought, eh? :-) Thanks for the kind words - great to hear I can still do it! I'll text you early next week if that's ok. Would love to catch up with you :-)

[@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...

[@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…

Hi, Gary. I am retired and moved from USA to the Philippines. Built a new house about 18 months ago. Regretably, I didn't give solar power a thought at the time. After about a year of experiencing what I thought were excessive monthy power bills ( USD $150 - $175), then it dawned on me that I should be using this tropical sunshine to my advantage. I am an

I am an absolute novice when it comes to solar power. So, I started checking things out on KZbin. Your site was about the fourth one I viewed. I wanted to let you know that I found your presentation very easy to follow and understand. I am looking forward to watching the rest of your videos and learning a more about solar power options. Keep up the good work, Gary.

[@GaryDoesSolar]

Thanks Robert - great that you found my videos! I’m sure you won’t be a novice for long either 😎 Sounds like your move from USA to The Philippines went well - I wish you the very best, and I’ll try to keep the videos coming! 👍🏻

[@robertpinkerton940]

@@GaryDoesSolar Wow! Thanks so much for the quick reponse. I am really impressed. YOU ARE THE REAL DEAL, MATE!. So far, you are the only site to respond to my messages. It took a couple of years of researching the Philippines before l made the move. So far, regrets! The only regret is that I did not come when I was a little younger. Been here a little over 8 years already. I have wonderful wife of 8 yrs. We are in the process of adopting a 1 yr old Philippine boy. A new challenge my life. I am looking forward to seeing more of your videos. Take good care!

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 👍🏻

Hi Gary - just looking through more of your videos and getting the info for micro inverters - all great info - I need to store on DC batteries too so that makes it a bit more of an issue with another standalone inverter - I'll get there ....... As far as companies house - every LTD company needs registered and I was told every VAT registered business in England needs to register but for some reason not Scotland - My company for 12 years has not needed to register and I am VAT registered (So - many smaller businesses may chose not to register - most of the bigger businesses are LTD and there for find it compulsory) @@GaryDoesSolar

@@craigstewart1878 Ah ok - I was referring to LTD companies - they need to be registered. If you're working as a sole trader or partnership, maybe you don't need to register.

Thank you sir for this very information and thorough presentation on Solar Energy Generation. You covered almost everything in professional details. I liked your channel and I appreciate your sharing with the general public. Thank you very much.

You are most welcome, Shaider 🙏 thanks for watching 👍🏻

[@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.
