New Hampshire has no state EV incentive — but solar-powered EV charging saves $1,200-$2,400 per year in gasoline costs. Long rural commutes make the savings even bigger. Section 30C gives you a $1,000 charger tax credit, but it expires June 30, 2026. Here is how to size your system and time it right.
This is the last federal incentive available for residential EV charging in New Hampshire. Do not miss this deadline.

NH has some of the longest commutes in New England. Many southern NH residents commute to Boston — 42+ miles each way. Rural residents drive 30-60 miles to work. These long commutes mean bigger fuel savings when powered by solar.
| Commute Route | Daily Miles | Annual EV kWh | Extra Solar | Gas Cost/Year | Solar EV Cost |
|---|---|---|---|---|---|
| Nashua to Boston (Route 3 / I-93) | 84 miles round-trip | 6,300-7,350 kWh/year | 4.5-5.5 kW extra | $2,625 (25 MPG, $3.13/gal) | $0 (solar-powered) |
| Manchester to Concord (I-93) | 36 miles round-trip | 2,700-3,150 kWh/year | 2.0-2.5 kW extra | $1,125 (25 MPG, $3.13/gal) | $0 (solar-powered) |
| Salem/Derry to Lowell/Lawrence MA | 30-50 miles round-trip | 2,250-4,375 kWh/year | 1.5-3.5 kW extra | $940-$1,560 (25 MPG) | $0 (solar-powered) |
| Rural NH (Laconia to Manchester) | 60 miles round-trip | 4,500-5,250 kWh/year | 3.0-4.0 kW extra | $1,875 (25 MPG) | $0 (solar-powered) |
| Average NH Driver | ~36 miles/day (NH avg) | 3,960-4,620 kWh/year | 2.5-3.5 kW extra | $1,650 (25 MPG) | $0 (solar-powered) |
The most common long commute in NH: Nashua to Boston via Route 3 / I-93. At 84 miles round-trip, an EV needs about 24-28 kWh per day. Annual consumption: 6,300-7,350 kWh. That requires 4.5-5.5 kW of additional solar capacity (10-13 extra panels). The cost: $8,000-$13,000 extra on your solar system. The savings: $2,625/year in eliminated gasoline at current NH prices ($3.13/gal). Payback on the extra solar: 3-5 years.
Different EVs have different efficiency ratings. A compact EV like a Chevy Bolt gets 3.5-4.0 miles per kWh. A Ford F-150 Lightning gets 2.0-2.5 miles per kWh. The truck needs nearly twice the solar capacity.

Annual miles / EV efficiency / 1,250 = extra kW of solar needed.
Example: 13,200 miles / 3.2 mi/kWh / 1,250 kWh per kW = 3.3 kW extra solar.
At NH solar costs of $3.03/W, that is $10,000 extra. At $2.80/W (volume discount on larger systems), it is $9,200. This extra capacity eliminates your fuel bill permanently.
For most NH EV owners with long commutes, a Level 2 charger is essential. Level 1 is only practical for short commuters or plug-in hybrids.
Best for: Short commuters (<30 miles/day). Plug-in hybrids. No installation needed.
Limitation: Too slow for long commuters. Takes 2-4 days to fully charge from empty.
Best for: Most NH EV owners. Fully charges any EV overnight. Can charge during solar peak hours.
Limitation: Requires dedicated 240V circuit. May need panel upgrade in older NH homes.
A Level 2 charger (240V, 40A) draws about 7.6-9.6 kW. During peak solar hours (10am-2pm), your solar panels can directly power the charger. A 10 kW solar system produces 6-8 kW during midday — enough to charge at near-full speed while the sun shines. For NH homeowners who work from home or have flexible schedules, this means zero-cost fuel for your EV. Smart chargers (ChargePoint, Emporia) can be scheduled to charge only during solar production hours.
Solar-powered EV driving is one of the best financial decisions an NH homeowner can make. Here is the full 10-year comparison for an average NH driver.
Winter hits EV efficiency and solar production simultaneously. Here is how to plan for it.
Unlike Massachusetts ($3,500 MOR-EV rebate), Connecticut ($2,000-$7,500 CHEAPR), or Vermont ($3,000-$5,000), New Hampshire offers zero state EV purchase incentive and zero state charger rebate. The only incentive is the federal Section 30C charger credit (up to $1,000, expires June 30, 2026).
NH is one of five states with no sales tax. An EV that costs $35,000 in Massachusetts incurs $2,188 in state sales tax (6.25%). In NH, that is $0. For a $50,000 EV, the savings are $3,125. This partially offsets the lack of a state EV incentive. Combined with lower property taxes in many NH towns and no income tax on wages, the total cost of ownership may still favor NH.
For the average NH driver (13,200 miles/year), you need an additional 2.5-3.5 kW of solar capacity, or about 6-8 extra 440W panels. This adds $5,500-$10,500 to your solar installation cost but eliminates $1,200-$2,400/year in gasoline costs. NH solar produces about 1,200-1,300 kWh per installed kW annually, so the math is straightforward: divide your annual EV kWh need by 1,250 to get the extra kW of solar needed.
Section 30C provides a 30% tax credit on EV charger equipment and installation costs, up to $1,000 for residential and $100,000 for commercial. The charger must be in a qualifying census tract (low-income or rural — most of NH qualifies). Critical deadline: Section 30C expires June 30, 2026. This is NOT a December 31 deadline. Install your charger before June 30, 2026 to claim the credit.
No. New Hampshire has no state EV purchase incentive, no state EV charger rebate, and no special EV electric rate. NH is one of the few New England states without any EV-specific state program. The only available incentive is the federal Section 30C charger credit (expires June 30, 2026). NH does exempt EVs from the state gas tax, but that is inherent to being electric.
In NH, net metering credits at ~85% of retail rate. This means if you export solar during the day and charge at night, you lose ~15% of the value. Ideally, charge during peak solar hours (10am-2pm) to maximize self-consumption. Many EVs and chargers have scheduling features. If you work from home, plug in during midday. If you commute, charge on weekends during solar peak. The difference is modest — maybe $50-$100/year — but it adds up.
NH solar production drops 60-70% in December/January compared to June/July. A system sized for annual EV needs will overproduce in summer and underproduce in winter. Net metering credits from summer production offset winter consumption. Over a full year, the math works. However, you will pull more from the grid in December-February and bank credits in June-August. EV efficiency also drops 20-30% in cold weather.
At NH gas prices of $3.13/gallon and 25 MPG average: 13,200 miles/year costs $1,650 in gas. The same miles in an EV at $0.27/kWh costs $1,190 from the grid. With solar, the electricity cost is effectively $0 (panels already paid for via net metering). Annual savings: $1,650 vs gas, $1,190 vs grid electricity. Over 10 years with solar: $16,500 in fuel savings.
A Level 2 charger requires a dedicated 240V, 40-50A circuit. Many older NH homes have 100-150A panels that may not have capacity for both a heat pump and EV charger. If your panel is already at capacity, an upgrade to 200A costs $2,000-$4,500. Some electricians can add a load-sharing device ($200-$500) that alternates power between the charger and other 240V loads, avoiding a full panel upgrade.
