Getting Paid for Your Extra Solar Power in Alton

Since Alton is in Texas's deregulated electricity market, there's no single 'net metering' law. Your compensation for surplus solar energy is determined by your chosen Retail Electric Provider (REP). Many REPs offer 'solar buyback plans' that credit your bill for the electricity you send to the grid. It's vital to shop for a plan with a favorable buyback rate; this is just as important as the rate you pay for electricity you pull from the grid at night. We can help you identify the best REPs in the Rio Grande Valley.
