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.

After reading the reviews and doing research, we decided to go with Sunergy. Before we signed a contract with them, we had multiple phone conversations with Brandon our sales rep. He answered every question and was quick to respond. The software they use to determine your cost is amazing. So far, so good.

After buying our first home we found that our electric and heating bills were unfathomably high. On average we were using 1500kwh per month and were spending $1,200 to $1,500 per month for oil and electric and it was untenable so after 6 months in our home we decided to look into Solar. The ecofriendly benefits were a bonus but realistically we desperately needed to stabilize our electric cost. I like to get as much information as possible to make the most financially sound decision and get the most bang for my buck. The first go around we received many quotes through Energy Sage, did a ton of research, and ultimately met with 8 different solar reps to review their proposals. We were pleased to learn that our house was somewhat of a golden goose for solar so we encountered so really aggressive salespeople who were promising the moon and 120% production estimates. Outside of the scheduled meetings we were getting doorknockers from newer companies frequently (sometimes multiple times per day) so it was important for me to find a company that had an established history in the business, were transparent, and realistic. Of all of the people we met with Molly Verville from All Energy Solar was the only one to tell me that it would be disingenuous to give us a production guarantee based on 6 months of electric usage data, recommended that we consult with an electrician, change our energy supplier, and prioritize weatherizing our home so that we can get a more accurate proposal. She gave one of the more conservative production estimates and actually raised some concerns about the impact that unnecessarily high production could have on our net metering credits due to some unimplemented legislative changes. I had a ton of questions and she knew her stuff. I never felt like she was trying to obfuscate or that she was just trying to make a quick sale which was a breath of fresh air. We followed her recs which were helpful and 6 months later we decided that buying solar panels still made the most sense and we had more reliable data to work from with updated proposals. We decided to go with All Energy knowing that we may be paying a bit more but would be getting top tier service. After signing our contract we were assigned to work with Carlo Maloni who was a great advocate for us through the process. He kept in communication with us with calls and emails every two weeks to keep us in the loop, ensured that if he didn’t know the answer to a question that he would get us in touch with someone who did, and made sure that we knew ahead of time if there were any potential delays. He coordinated a seamless transition of our project to his manager Annalise for the 2 months while he was on paternity leave, and when he came back he picked things up with us right were we left off fully up to speed. Our panels have been on for almost two months and they were so proactive with startup monitoring that in the first couple of weeks they identified a minor issue before I was even aware of it and their electrician Mike came over the same day to make sure it was fixed. So far our production has been exceeding our consumption and it the monitoring app has been extremely useful for us to be able to identify what is still contributing to high usage. Overall, working with him and everyone from All Energy made this a painless process. I am really happy we chose All Energy and I would wholeheartedly recommend them to anyone looking to switch to solar.

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.

New England Clean Energy Clean, courteous, hard working and meticulous are only a few ways to describe installation crew that professionally installed my families PV solar system on our home. My wife and I were hesitant to make such a drastic change and investment to our home but New England Clean Energy made it a pressure free experience and we have been ecstatic with our decision. We met with over a dozen solar companies and many proved they would not be able to meet our high standards. From Mark in sales to the site supervisor JJ, New England Clean Energy proved they were right choice and delivered as promised!

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!
