yeah - I've got 3m^2 producing at its best 4.6kWc, which is made up from 2 panels of 10x230W panels. Produces all the hot water no problem for a family of 4 and the rest we sell back to the electricity company. That way, stuff for lighting, electricity kitchen hob etc is covered and the electricity company pays us an avg of €80/month for the electricity we give them.
So, with 15k investment (25k being payed for in tax breaks from the govt), we live electricty bill free and gain ~€1000 from the electricity company.
It will start making profit in about 5-6 years....
