I see a lot of Solar advocates here and in the media. I looked into it and found it impossible for me because of cost. I looked at a simple 3 Kilowatt, 16 Panel system which is tied to my electric company grid so all I produce just reduces my bill. The cost installed is about $ 20,000.
I did some research on life of equipment, hours of sunlight, etc., and figure I can only reliably get a max. of about 20 Kilowatt-Hours (KWH) a day 70-80 percent of the time, or about 5000-6000 KWH a year. I assumed a 10 year life of the equipment.
I pay about 10 cents/ KWH for my power, so the system will save me maybe $ 600/year.
This is rediculous. The system cost me $ 3000/year (2000 depreciation and 1000 interest @ 5%). The system will never pay itself off. Even if I cut the cost in half, it will not come close to reasonable power costs.
How can anyone promote this as a viable alternative? Maybe it will when power costs on the grid quadruple or more.
