Get a Free QuoteAt 28¢/kWh, every kilowatt-hour your solar system produces instead of buying from the grid saves you real money. Calculate exactly how much solar covers your EV — sized for Massachusetts's sun and your driving habits.
With electricity rates averaging $0.28/kWh — roughly double the national average — Massachusetts homeowners pay more to charge an EV from the grid than almost any other state. The good news: Massachusetts also has the most mature solar incentive stack in the region. The SMART 3.0 program pays a guaranteed per-kWh rate for 10 years, and Mass Save offers up to $700 back on Level 2 EV charger installation. When you size your solar system to cover EV charging, you lock in a near-zero effective fuel rate while eliminating exposure to some of the most volatile electricity prices in the country.

SMART 3.0 pays a guaranteed per-kWh rate on every kilowatt-hour your solar system produces — whether you use it in your home, charge your EV, or export it to the grid. The compensation rate depends on your utility (Eversource, National Grid, Unitil) and system size. When you size your solar system to cover your EV load, SMART payments accelerate your payback while you eliminate the fuel cost.
Mass Save offers rebates of up to $700 on the purchase and installation of a Level 2 EV charger through participating utilities. Combined with smart charging that uses your solar production, this rebate brings the total cost of a home charging solution down significantly. NuWatt handles the Mass Save paperwork as part of the project.
The calculator uses real state peak sun hours, current utility rate data, and manufacturer-standard vehicle efficiency figures. System derate factor is 0.80 (NREL standard for real-world losses). Estimates are within ±15% of a precise NuWatt design, which factors in your actual roof orientation, shading, and local utility interconnection rules.

Yes — and it is often the most cost-effective approach. NuWatt coordinates solar system design, panel installation, EV charger wiring, and permit filing as a single project. Combining the work reduces labor costs, requires only one set of permits and utility paperwork, and lets us right-size the electrical panel upgrade to handle both loads simultaneously.
