How many solar panels does it take to power a three bedroom house, and how much would it cost?
Question:
Answer:
Can't help with the cost, but my 6 kW photovoltaic solar system has 40 panels. In Martinez CA I get an annual average of about 20 kWh per day. Check your utility bills and see how much you use. That will give you a rough idea of what to expect.
You could check with your building department to determine where solar systems have been installed in your area. Most folks who have them are willing to talk about them.
