With the latest jump in electricity price, a lot of us have been looking for PV as an alternative and potentially with a battery to store any extras. I am personally considering a 4Kw system which I found to be the sweet spot at the moment with 330W panels the norm on the market. But it is a bit of a minefield as there - at least from me. Cheapest I got was from a company called constant solar, with glow green being the next cheapest (less than £5K with a battery). However, they are small fish compared to the best known of them all EON. So, I'm keen to hear what others have paid/experienced.
