How Net Metering Works in Massachusetts
When your panels produce more electricity than your home is using, the surplus flows back onto the grid and your meter records the export. Massachusetts utilities credit those exported kilowatt-hours at retail rate minus a grid-access or non-bypassable charge. You draw that credit back down at night or on cloudy days, so you only pay for your net consumption across the billing cycle.
Because Massachusetts mandates net metering, a correctly sized system can push net annual electricity costs close to zero for many MA homeowners.
What It's Worth: ~70–90% of retail of Retail
The single biggest driver of solar payback is how much your utility pays for exported energy. Massachusetts's modified structure keeps most of the retail value but subtracts a grid-access or non-bypassable charge, so model your specific utility's deductions.
