That was my thoughts too. Being double charged for installation. I think a lot of it is because supply is so limited at the moment and the companies can get away with it, from the quotes seen here my quote is not outrageous but when you look at the price for the parts it seems we are all being ripped off. There is a 25 year minimum production warranty included where they monitor the system and if the efficiency drops either replace parts or pay your electricity bill, however, will they/their insurance company even exist in 25 years times? The problem is, there is no way I can self supply/install as nobody will certify the system.
Well had my visit tonight , a wee bit underwhelmed actually . Guy was not convinced about my roof . Could have shadows at some point in the day. I’ll need to check it out myself maybe over the weekend . Sunny day preferable . Only quoted for 5kw and 6.5kw battery . The numbers to me take a long time to stack up. After the outlay it could take 15yrs to be in the black. Seems a hell of long time . I’ve got another company coming in a couple of weeks so I will compare. Price wise a wee bit more than the guy that emailed only. However still north of £12k ! Only upside is the interest free loan for £11k of that via Sco Gov. However I get the feeling your being charged a tad more than it should be ?!
Could somebody explain this whole Solar operation gently to me?
Just moved into a new-build with 4kW of solar panel installed. No batteries.
Right now we are with British Gas and need to speak to the Solar feed-in team - and I know bugger-all about how this works. Also I believe there are also options with Octopus.
Is there an idiots guide?
What do I need to know/consider.
Is a battery a good investment and what size?
Is there an 'APP' that can monitor what's going-on?
Lecktrickery, is a foreign country to me, but I want to maximise the benefit of what we have.....
If you have a bit of shadowing, ensure that the panel are individually wired and not in series. Then if one panel becomes shadowed, only that panel drops off in output. Series wired panels, if one panel shadows the whole set of panels reduce output.
The use of micro invertors on each panel or optimisers help mitigate shadowing.
