What Do I Need To Convert My House To Solar Power?
I have a small house with basic asphalt shingles. I use about 2100 kw a month in power because of the A/C. (It gets somewhere between 99f-102f.) I was looking at the solar panels at http://www.solarhome.org/solarpanelscenter.html and was shocked at the prices of it. If I use 83 kw a day, how much would i need to bring this down from using the power grid? I want to one day be totally off the power grid. From my understanding they create 200w per day, I think I am wrong, so if you can answer this question, can you all help?
Your best return on investment is solar hot water, then superinsulating the house, then photovoltaic.
My rule of thumb is you get about 50% of peak power for about 8 hours a day from a solar panel. Your 83 kWhr/day would require about 21 kW of panels to completely replace your grid power, around $60k at today's prices. Your local power company may have subsidy/buyback policies to bring down the purchase price requirements. Insulation to bring down your A/C requirements will pay you back faster than the PV panels will. We're off-grid, good house insulation lets us be quite happy with less than 10 kWhr/day of solar power.
