SunPower and Naturener Partner on 9-Megawatt Spanish Solar Power Plant
SunPower Corp. announced today that it is building a 9.1-megawatt solar power plant in Alange, Badajoz, Spain for the Naturener Group. This will be the fifth solar power plant that SunPower has designed and constructed for Naturener Group to date, and one of the largest to be commissioned in Spain this year.
Is Solar Power really an option for most homeowners?
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.
For ordinary people like yourself its a waist of money . The price tag is way to high . For guys like me the solar cell is sent from heaven . I build my panels from scrap broken cells and build small wind mills from junk i have a few pics in my blog . For the average guy it is ridiculous to pay that much . Your best off holding off until they come out with a better solution for energy .
