Ronski's Solar & battery DIY build with whole house backup

[Ron-ski]

I'll be honest i'm not convinced with wall mounted ones. Theres a house near my parents with none on the roof, but the walls are covered. I'd imagine its planning related

I think there's a massive difference between my installation and theirs. They are almost certainly a very poor DIY install, not only do they look unsightly they must be heavily shaded, so not very effective. Clearly the home owner didn't have the skil or knowledge to do a roof installation, and didn't want to pay for a proper install.

The roof may also be in very poor condition and is effectively at the end of its life.

I'd be very surprised if that roof is at end of life, it will just be as I've said above

And as Fraser says, very unlikely to be planning related, it won't be a listed building, could be a conservation zone, but then they'd still need permission for wall mount.

Whats the betting thats an illegal install. Clearly over the minimum amount your allowed to install without notifying DNO. (approx 1kw)
Probably just stuffed into the CU or even directly into a circuit that runs close.

Perhaps we should start a thread for really bad solar installs.

@Ron-ski do you know anyone who has built a Seplos kit, the vertical version? A pal is looking to setup some storage, and is looking at these as an option. Also Fogstar or direct from AliExpress?

I don't personally know anybody that's built one, or even anyone I know on forums, obviously Andy's Off Grid Garage has.

If you want ultimate savings, then probably direct from China, if you want a bit more support should something go wrong and less chance of dodgy cells then Fogstar - although they seem to be out of stock of complete kits.

You used to be able to order off the Fogstar Wholesale website for a bit of extra discount, but I see you need to register now, but if order a large quantity of cells may be worth requesting a bulk price.

DIY case and 16 x 314AH grade A EVE cells, thus 15 kWh battery for £1800, great value.

Actually, by the time you've paid shipping, and potential import/vat duties I'm not even sure if you can get them for that price from China.

There are also some concerns about cells laying on their sides, I've no idea whether it is actually a problem though.

Seplos V4 ?
