Net Metering

Net metering allows residential and commercial customers who generate their own electricity from solar power to feed electricity they do not use back into the grid. Many states have passed net metering laws. In other states, utilities may offer net metering programs voluntarily or as a result of regulatory decisions. Differences between states' legislation and implementation mean that the benefits of net metering can vary widely for solar customers in different areas of the country.

Remember that utilities only pay a wholesale rate and so the money you get is generally not worth the rights you give up to have their wires on your land. They have a right of way to enter your property day or night without your permission. When you provide your own power, you can tell them to get their crap off your land and never come back, ever!
