Do all states require utilities to offer net metering?
Many, but not all, states require utilities to offer net metering, but the size and technology requirements vary. If your state does not provide for net metering, you can still use the electricity in your house and enjoy the benefits of clean reliable power from the sun. However, you must purchase a second meter to measure the amount of electricity your system produces and make special arrangements with the utility to receive credit for excess electricity produced by your solar electric system.
