Get a Free QuoteAt 29¢/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 Connecticut's sun and your driving habits.
Connecticut homeowners face the highest electricity rates in the contiguous US at $0.29/kWh, making EV charging from the grid genuinely expensive. Those same high rates make solar ROI exceptionally compelling — every kilowatt-hour you self-generate is worth $0.29 in avoided costs. Energize CT's Smart-E Loan offers 0% financing for EV charger installation, and the Energy Storage Solutions (ESS) program from Eversource CT and United Illuminating provides incentives for battery storage alongside solar. A properly sized solar+EV system in Connecticut can eliminate the equivalent of $150–250/month in combined electricity and fuel costs.

The Smart-E Loan provides 0% interest financing for energy efficiency and clean energy upgrades including EV charger installation. It is administered through participating lenders across Connecticut. For an EV charger installation typically costing $1,500–$2,500, this means zero carrying cost on financing. Paired with solar savings at $0.29/kWh avoided, the monthly benefit often exceeds any loan payment.
Both Eversource CT and United Illuminating operate under similar net metering and Energy Storage Solutions (ESS) program rules. Eversource CT serves the largest share of CT customers. United Illuminating serves the New Haven and Bridgeport areas. The ESS program incentivizes battery storage alongside solar in both territories, which pairs well with EV charging to maximize self-consumption.
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.
