I bought 3.5kw and a 10kwh battery in June and it’s amazing. Bills are 90% cheaper and it’ll pay for itself in 5 years with underwritten warranties for 25 years on the panels and 15 on the battery

There used to be shops in the UK where you could rent electrical and white goods. Radio Rentals. Existed until electronics from Asia became so cheap.
