For those of us in the UK that jumped on board the Feed In Tariff when it was its highest rate we receive about £2400 per year with the usual inflation increases tax free.
the maths were Panels purchase £12000 then a £2000 per year return over 25 years = £50,000 without the inflationary increases
Quite a good deal from the UK government, and then there is the free electric, for the first 10 years the mechanical meter went backwards so that helped too!
