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.

In September 2024 New England Clean Energy installed a 22-panel solar system on my roof. The sales, design, installation, town inspections for the project went extremely well. During the sales discussions software was used to evaluate the roof size and shape, house orientation, and the effect of nearby trees for several possible panel configurations to determine the optimal power output. During installation the installers offered several good options for running the wiring to minimize visibility on the exterior of the house. The final installation seemed very high quality. Installation required about 2 days including several hours of delay due to heavy rain. The installation passed the town fire, building, and electrical inspections, and was accepted by National Grid without any problems. The system has been up and running flawlessly for several weeks. I recommend New England Clean Energy as an excellent choice for solar projects.

I have yet to have multi-day power outage since installing 2-13.5 kwh SunVault batteries. During winter months I leave fully charged since sun & possible snow cover will impede solar production, so a fail-safe for the long power outage possibility. Now that better weather is here and not worried about freezing pipes, I am running the batteries overnight to power the home. So far, has the SunVault system has been working great with balancing the battery, grid and solar production usage in the home. I use about 50% of the batteries (one battery) each evening and it is typically charged up by 11 am local time, a little later on the cloudy days (yes, arrays still produce). My system is sized enough to power home on all but the darkest days where the battery supplements. If we get multiple days of rain, then I'm back on the grid using some of the credits I have stored at Eversource after the batteries are 100% recharged each day. I have no idea when the SunVault system switches to battery from the grid and vice versa, no issues with any electronics in the home when it does and it works in the "normal" daily living space fantastically. I will update this review if my micro-grid fails during a multi-day grid power outage as it is my expectation the solar array will not be shut down so the house and batteries can use the produced electricity until the grid is repaired. This is the real reason I go the batteries as had a 2018 summer Tropical Storm knock out power for 6-days and it was sunny for 5 of those days but my solar array was useless without a battery system attached. Fingers crossed this works as promoted and promised. The staff was great at every process of the sales, install and post-install support process as there are always questions and weird things with electricity that sometimes needs a call. Thank you, Jordan, my install team and Kim for helping and teaching me about the system. SavKat is a local, family-owned operation that is simply the best, highly recommend talking to them before going too far into your solar planning.

The company I chose to install my solar panels, Venture Home Solar LLC, were A+. Professional, courteous and patient with my questions. Once they started the job it was completed in just a few days. They called to let me know when they were coming to the house before each procedure. If they were going to be late, they called to let me know. Every man on the team got along and the work went smoothly. I liked that they didn't smoke on my property and they used clean language while speaking with each other. I recommend this company highly! - A F P - Auburn, Maine

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!
