I have also been investigating purchasing a solar p.v. panels to free my house from the national grid. Using my electricity bill and using information on
I calculated that I could totally replace my electricity supply with 17 solar panel units each covering 8sqm. The cost is a whopping £102000 about ($204000). Ignoring interest thatís a 76 year payback period and the system only lasts 25 years.
Does any green initiative actually stack up on paper or is simply a costly gesture?

Quoted install cost is about 60% higher than Long Island currency adjusted (not a cheap place).

Does not include any tax benefits or incentives or grants etc.

Cost of energy appears a little low.

Major system components are warrenteed for 25 years (that's different to system lifetime).

Look at for a US alternative.
