Solar power in New Hampshire

Last fact-checked on April 14, 2023, by Catherine Lane

New Hampshire is one of the best places in the nation to install solar panels. A combination of high average sun exposure, expensive utility rates, the solar tax credit, and the state's net metering law means homeowners can get an excellent return by installing solar panels.
But, New Hampshire net metering rules have changed, causing solar panels to save less money than they have in the past. Don't worry, New Hampshirites can still see an excellent return on investment under the new rules, and battery storage is now a more economical choice.

What are the pros and cons of installing solar panels in New Hampshire?

The advantages of installing solar panels in New Hampshire are that there are both state-based incentives and the federal tax credit to help reduce system costs. In addition, much like everything else in New Hampshire, power is expensive! High electric rates means you have the potential to save more money, making the overall return on investment for residential solar panels in the state much higher than other states in the nation.

The disadvantage of installing solar panels in New Hampshire is that there is less overall solar irradiation. This means a system in New Hampshire will produce less power than a system in sunnier states, like Arizona. However, the state and local incentives more than make up for this. New Hampshire homeowners should not pass up the opportunity to install solar while these amazing incentives are still in place.
