The state of solar in New Hampshire

If you live in New Hampshire and are considering going solar to reduce your energy bills and carbon footprint, you are on the right track. The White Mountain State experiences 198 sunny days each year and has several laws that incentivize switching to solar energy.*

According to Google’s Project Sunroof, if 72% of the buildings in New Hampshire installed solar panels, the state could generate up to 2.6 million MWh AC each year.*


How much solar energy does New Hampshire produce?

In the first quarter of 2021, New Hampshire had 9,966 solar installations that could generate 140.5 MW of electricity – enough power for over 20,000 homes. One of the largest solar installations in the state is the Peterborough Solar Array, a photovoltaic solar system that produces 1 MW of electricity.*

What are the advantages of going solar in New Hampshire?

The average residential electricity rate in New Hampshire is 35.27% higher than the national average.*

Switching to solar energy today could save you $28,527 to $38,596 over the next 20 years. Even though installing a solar system is pricey, the money you save by installing a system today would cover the cost of your investment within seven to ten years.*

Also, installing solar panels on your home today would future-proof your property as the world continues to gravitate towards clean energy. Even better, installing solar panels on your home can increase its market value by tens of thousands of dollars. The considerable return on investment makes solar installation one of the most valuable home renovations you can perform.

The cost of a home solar system can vary, even in the same state, due to a range of factors. These include:

  • Quality of the solar panels

  • Permit costs

  • Installer rates

  • Roof age, angle, and size

  • Weather

To help you understand the price of going solar in your area, we've analyzed SunPower price quotes, as well as quotes gathered by third-party sources for thousands of homeowners across the country. In New Hampshire, we found that the average investment to own a 5 kW solar system ranges from $14,800 to $15,850, or in other words, from $2.96 to $3.17 per watt—and that's before considering the benefits of any available tax credits or incentives.

You will be able to reduce the cost of switching to solar power by taking advantage of these incentives and rebates:

  • The federal solar tax credit: Homeowners who purchase their system as opposed to leasing it, can get a tax credit of up to 26% of the total cost of the solar installation.*

  • Renewable Energy Generation Incentive Program: If you install a solar system with a 10 kW capacity or less, the New Hampshire Public Utilities Commission (PUC) has a rebate program for residential electric generating systems. You can apply through the PUC Sustainable Energy Division. This state program entitles you to $0.20 per watt that your system generates. You can collect up to $1,000 or half of the cost of installing your system.

  • New Hampshire Electric Cooperative: Co-op members also receive renewable energy rebate programs offered that you may use in combination with the PUC rebates.

  • Local property tax exemption: Installing a solar system increases your property’s value. Thanks to New Hampshire’s tax exemption laws, you may not have to pay taxes on the added property value from a solar panel installation. Since not all counties administer this uniformly, please check to determine your county or municipality’s status regarding the tax exemption.

  • Net metering: If you have a 1 MW or smaller solar system, net metering from the NH Public Utilities Commission ensures that you will get paid for excess electricity generated by your system that goes to the grid. Eversource has one of the best net metering policies in New Hampshire.*
