My OH thinks we should be buying from Hone as it produces on cloudy days not only sunny. I’ve read the ‘snake oil’ comments here but has anyone actually used them? Or know of one one who has used them? Their website cases are heating systems but were only doing electricity. Many thanks, hopefully somebody can help me �� as he’s quite convinced !!

One system is about 1000 euro cheaper and for a slightly bigger array (1.5kw bigger). This supplier is using a solis inverter and he can use either JA 410w, Q Cell 375w or Trina 370w panels for roughly the same price. All these panels have a 12 year product warranty and 25 year output warranty. The other supplier says he cant come down any further in price because he is using much better panels and inverter. He has quoted for an Alpha inverter and Jinko panels which have a 25year product warranty and 30 year output warranty. My gut is telling me the additional warranty is not worth the extra grand and the loss of 1.5kw. Im thinking of going with the JA 410w panels. Any opinions one way or the other?

garo wrote: » If you are going to go for a grant aided install, adding a battery gets you 1200 extra grant. That covers a good bit of the cost. Having a battery does mean that if a cloud passes over when the oven is on you don't import or import less and you also contribute to lowering the evening peak. It's not a no-brainer either way. A high FiT rate may make it so but chances are we get 5-6c which means we are back to "could go either way".For non-grant installs I would say that a battery is now definitely not going to be worth it after the FiT.

It looks like most are suggesting batteries are not worth it when you can supply any extra back to grid. Am I looking at 4kw of panels? New to this, so any help appreciated. C1 BER so should get grant.

Im pulling some data directly from the storage inverter over a serial connection.
