Dick's house in France
NO ELECTRICITY BILLS?
With 19 PV panels facing due south, with a maximum power of nearly 5 Kw, the house generates a lot of electricity.
Some of the electricity is used in the house - so, for instance, the washing machine and dishwasher are used during daylight hours.
Most of the electricity, the surplus, is sold to EDF, for which there is a small payment, not as generous as the UK FIT scheme, but enough to give a return of over 5%, tax free, on the capital cost.
I still have to buy electricity, of course, but I expect the income from EDF to be very nearly the same as the bills.
