NuWatt designs, installs, and manages solar, battery, heat pump, and EV charger systems across 9 states. One company, one warranty, one point of contact.
Get a Free QuoteAt 22¢/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 Vermont's sun and your driving habits.
Vermont has some of the most forward-thinking utility EV programs in the country. Green Mountain Power offers Time-of-Use rates designed specifically for EV households, with off-peak rates as low as $0.10/kWh during overnight hours. GMP also runs a smart charging enrollment program that lets your charger respond to grid signals and solar production. Vermont's net metering credit rate is among the highest in the region, making excess solar production genuinely valuable. Burlington Electric Department customers have additional options for local net metering credits. Vermont's shorter peak sun hours (4.0/day) favor larger solar systems sized to handle winter EV loads.

Green Mountain Power's smart charging enrollment program allows your EV charger to receive signals from GMP to adjust charging times based on grid conditions and your solar production. During high solar generation periods, the charger prioritizes solar energy. During peak grid demand, it can pause or reduce charging to reduce grid stress. GMP customers who enroll often receive bill credits or rate benefits for participation.
Vermont's net metering credits are calculated at a rate set by the Public Utility Commission. Green Mountain Power customers receive credits for excess solar at rates that are among the most favorable in New England. Burlington Electric Department customers have a separate local net metering program. Vermont's credit structure makes oversizing your solar system (to cover winter EV charging) financially worthwhile.
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.
