Solar net metering is a smart, rewarding way to get the most out of your solar panel system. It works by sending extra electricity your panels produce back to the power grid, sometimes even letting you sell solar energy back to the grid. In return, you earn credits that can lower. . Net metering isn't direct selling – You're not actually selling electricity for cash, but receiving credits that reduce future utility bills. Most homeowners see $600-1,500 in annual bill reductions rather than income payments. Location dramatically impacts profitability – With 34 states plus D. In fact, in states like California, some homeowners can earn up to $3,000 a year just by exporting extra electricity. Can You Sell Energy Back To The Grid? Although many people with solar systems on their homes or businesses think that they can sell excess electricity to the. . Find the best solar pros in your area.
