solar power companies
Does anybody here have solar panels and sell the extra electricity to the power company?
How much power with what kind of solar panels do you average making a day or month and how much do you sell and how much money do you make from selling electric to the electric company?
The answer depends on a lot of things.
1) In the US, any public utility company is required to buy back your excess power. Some small companies, like Co-ops and municipal companies, are except from this requirement. However, there is no regulation about how much they have to buy it for. Some companies buy it back at the same rate they sell it. So if you sell 500kwh a month, and buy 500kwh a month, your bill would be $0 (or a small connection fee). Some pay you an “avoided cost” rate, what they buy from other power plants, at a fraction of what they sell it for. So you may buy it at $0.15 per kwh, but they’ll buy any extra from you for $0.05. Some companies limit you to zeroing out your bill, some will write you a check for whatever you generate.
2) How much power you use would determine how big of a system you need. If you buy 1000kwh per month, you would need a system big enough to generate that much during the day, so you can sell the excess during the day, and buy it back at night. That way, you don’t need batteries for night, you basically use the electric company to hold your extra power until you need it later. Check out how many kwh you buy a month from the electric company, it will be listed on your electric bill. Plug that number into the calculator at http://www.altestore.com/store/calculators/on_grid_calculator/. That will tell you how big of a system you need.
You know the expression it takes money to make money? It will cost a lot to buy a system bigger than what you need, and with few exceptions, will most likely not make you money selling power back. It’s a better investment to first spend your money on conserving electricity, it costs less money to save electricity than to make it. Once you have cut your requirements, THEN look into buying a solar system.
Most people buy a system big enough to generate a percentage of what they use, therefore reducing their bill, not eliminating it, and certainly not making money on it. Many tax incentives are available to help pay for it, you can see them at http://www.dsireusa.org.
