we recently in March had a 4 .44 kW solar 12 panel system complete with a HIES 10 year backed guarantee which covers both the panels, workmanship and invertor, it was a local well established company which has been trading for many years, cost £4,900.
We are 100% happy charge up the PHEV, our fuel cost has dropped dramatically since March this year.
Unfortunately I have suffered a brain injury and occasionally I get confused and often say the wrong thing.
