In most areas, net metering connects your home’s power to the local grid, allowing you to send excess power back to your utility. There may be a connection fee to get the process started. Once it's in place, your electric meter tracks your usage, ultimately delivering monthly savings. If you sell power to the grid, your meter counts backward. When you're using more power than you generate, it counts upwards. At the end of the month, you only pay for the energy you use after all your credits are deducted.
