How to use
Massachusetts pays via the SMART program (fixed monthly incentive per kW) plus a state tax credit; high electricity rates make solar attractive despite modest sun. This page pre-fills a 6 kW system with Massachusetts's 4 peak-sun hours, $0.30/kWh rate and a net metering credit of 0.85. Adjust the system size, installed cost and federal ITC, then press Calculate.
The simple payback divides your net cost (after the 30% federal ITC and the $1,000 state incentive) by your first-year savings. Because electricity prices usually rise, the 25-year total understates your real savings if you leave the 3% default in place.
