I'm so relieved I came across these reviews. We have had our sales talk from Project Solar UK and have been quoted £16,000 for 10 panels. Being distrustful, though it was a very good pitch, I decided to do a bit more research. What made me very suspicious was the claim of a 99 year warranty on the panels and inverter. What on earth lasts 99 years and what's the point if were already pensioners. We were told this warranty was underwritten by Lloyds so even if the company folded, our warranty still stood with Lloyds. I wonder what Lloyds reaction would be if, in 50 years, the new home owners demanded a refund under warranty 'cos the inverter failed.
