There can be solar tax credits and incentives available at the federal, state and local levels. The calculator above will show you the value of all incentives your home is eligible for.
New Hampshire got its solar policy on the right track right pretty early. The General Court passed a strong Renewables Portfolio Standard (RPS) back in 2007. With it came a good statewide rebate program to lower the up-front price of solar. It's now almost a decade and a half later, and the state still has strong rebates and high electricity prices, which are the major reasons solar is a great investment here.
Several times over the last two years, lawmakers passed bills to expand New Hampshire’s net metering rules, which help homeowners further by allowing them to harvest more credit for their solar power they produce but aren’t able to use onsite.
However, governor Chris Sununu has vetoed all of them so far. The RPS here could be strengthened as well. Unless something changes, things will start looking a little dimmer for homeowners looking to install solar here soon. Regardless, for 2021, the state rebate program is strong and there are decent low income solar programs to boot. New Hampshire continues to be a strong place to go solar.

The federal solar investment tax credit will have the biggest impact on the cost you will face to go solar in New Hampshire
If you install your photovoltaic system before the end of 2032, the federal tax credit is 30% of the cost of your solar panel system. This is 30% off the entire cost of the system including equipment, labor, and permitting.
Example: If your solar energy system costs $20,000, your federal solar tax credit would be $20,000 x 30% = $6,000.
The federal tax credit falls to 26% starting in 2033.
With net metering in some states, you get full retail rate credit for the amount of electricity you send back into the grid with your solar panels.
Net Metering requires your utility to monitor how much energy your solar power system produces and how much energy you actually consume, and make sure you get credit for the surplus.
The New Hampshire public utilities commission (PUC) made rules that require all utilities to offer net metering to residential customers. Surplus energy is applied as a credit to your next month’s bill at full retail electric rates, and credits can be carried over indefinitely. In addition, if you’re on a default service plan you can get annual payments for net metering surplus, if the surplus exceeds 600 kilowatt-hours (kWh).
That’s a very strong rule, but there might be changes coming soon. H.B. 1116, enacted in May 2016, raises New Hampshire's net metering aggregate capacity limit from 50 MW to 100 MW. The bill also directs the Public Utilities Commission to initiate a proceeding to develop new alternative net metering tariffs. That could spell trouble, as other formerly solar-friendly states have not proven good at coming up with replacement for net metering.
We recommend going solar as soon as possible to lock in your net metering rates.
The New Hampshire Public Utilities Commission (“PUC”) runs a statewide solar power rebate program that offers $200 per kilowatt (kW), up to $1,000 or 30% of project costs, whichever is less. All residential systems are eligible for the rebate, but because the maximum incentive is $1,000, that means a de facto cap of 5-kW for the rebate.
Keep in mind, this incentive has to be applied for and approved before you begin construction, so get your ducks in a row by working with a trusted installer. Use our solar calculator on this page to get started working with one.
When you install a solar power system, your home appreciates by twenty times your annual electricity savings. Luckily, New Hampshire allows cities and towns to exempt that increase in home value from all associated property taxes.
More than 80 cities and towns in New Hampshire have adopted a property tax exemption for one or more of these energy sources. Here's a full list of the cities and towns that have adopted a property tax exemption for solar power. Don’t fret the details; expert solar installers we partner with will walk you through all the details.

Sunergy made it super smooth and easy to get solar. We had need of a large system to sustain a lot of computing, EV usage, and heatpump, so ended up drafting out a 12.75kW array. Their representative John Parlator kept in close contact through the whole process, from design to aftersale support, making sure that all of our needs are met. Very happy to have chosen Sunergy.

The process of getting the 26 panel system installed was super easy. New England answered all of my question and explained the whole process very well. All the guys that did the installation were friendly and courteous. The electrical work was very neatly done and looks professional. I would recommend this company over any of the other solar companies out there. Now I just have to have the electric company come and switch my meter. At that point I can watch the dial go backwards on a nice sunny day.

From start to finish this was an exceptional process. It was a throwback to a time when customer service was all about the customer. We were kept informed every step of the way, called if there was a delay for any reason, work was done timely, staff were more than competent and I was completely comfortable having them in and on my home. The work area was always cleaned before they left for the day. It was so refreshing to work with a company that does quality work, with quality products and cares about the client experience from start to finish.

From the start of my time working with 603 Solar, Zach and the team were extremely knowledgeable, transparent, and prompt! Zach answered all of my questions that I first had during our initial phone conversation in June. At the time, the Federal credit was going to be reduced from 26% to 22%. Understanding that greater than 6 months was an unreasonable leadtime, Zach assured me that if my project was not completed before 12/31/2022, 603 Solar would have given me the additional 4% credit I would have lost. We also ran into a few slight hiccups with my town building inspector, but Zach kept me in the loop every step of the way and was able to come to a resolution to keep our project moving forward. I would highly recommend Zach and 603 Solar for your project!
