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.

Rob and the entire team at Sunergy have been great to work with. They took the time to explain everything clearly and made sure I felt comfortable throughout the entire process. From the proposal and installation to permits and ongoing support, Sunergy has been excellent every step of the way. My father used Sunergy for his solar project and later recommended them to three other friends. After my own experience, I can see why. I will definitely be recommending them to my friends and will use them again for any future solar service needs.

When I purchased this house in 2018, the solar installation company the previous owners had used had gone out of business. I knew zero about solar panels or their maintenance so luckily for me, I found New England Clean Energy. They came right out, explained the system and did some upgrades at a very reasonable cost. They also mapped the system so I can track it on the Solar Edge app. Recently the app stopped being able to record data. They sent a super technician to replace a faulty plug and the app started communicating again. Whether you’re looking for a new system or a great company to help you manage it, NECE is the only company you should contact. Highly recommend!

My experience with Revision was so positive. Everyone they sent to carefully assess my site was informative, careful, thoughtful and professional. They answered every question I had with patience, they explained each step thoroughly, they were kind and understanding, and made every effort to not only make the system work well, but also look right on my historic home and give me a realistic view of the project. If there needed to be changes, they explained what they were going to do and why it was necessary. I found the entire process incredibly transparent and informative, and got assistance all the way from the initial interaction to the tax rebate process at the end. I have recommended their services and expertise to many people in our area.

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!

Extremely happy with the job Harvey Woods did. From start to finish they were exemplary. Great team to work with. We turned on our panels on Jan 21, 2025 about 3 months after initial contact in the bidding process. Yes they installed in December despite cold temperatures. They always put safety first. Their pricing is competitive, but even better, their communication is top-notch. No question goes unanswered. Willing to explain things as deeply as needed. They handled all paperwork and were timely with all paperwork. They may not have done thousands of installs, but as a small company you get the personal touch. They take full ownership being deeply involved in the installation. I highly, highly recommend this team. The schedule rated 4 due to the permitting process taking 3 weeks longer than estimated.

Peter and Vlad have been great to deal with. They are both very knowledgeable and true professionals in their field. We had recently purchase a home with an existing system and they helped us in making sure the system was working correctly and spent a lot of time going over and making sure that I understood how everything worked. It's refreshing to see that they have a true passion and would highly recommend them for any of your solar needs.
