Home Incentives Solar Savings Calculator

Free · 60 seconds · No obligation

Solar savings calculator

Enter your monthly electric bill and ZIP to estimate your system size and your net-metering bill savings. SMART is calculated per project. It's an estimate — book a free assessment and we'll model the exact numbers for your roof.

Estimate uses a Massachusetts average retail rate (~31.5¢/kWh) and typical MA production (~1,150 kWh per kW/yr). SMART is a separate production incentive calculated per project — we compute it at your assessment. Your real numbers depend on your roof, usage, and utility.
