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
This perk is commonly known as the ITC, short for “Investment Tax Credit”. If you install your photovoltaic system in 2020, the federal tax credit is 26% of the cost of your solar panel system. This is 26% 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 26% = $5,200.
The federal tax credit falls to 22% at the end of 2022.
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.

Our installation couldn’t have gone any better! Our project manager Carlo couldn’t have been a better communicator… He handled everything from permitting to coordinating the final closeout with NGrid. The installation crew was quick, easy to get along with and respectful of our property. I highly recommend All Energy Solar!

We are thrilled with our panels and the ReVision Energy Team. The options were clearly laid out and they presented models of energy capture given our roof configuration. And the Installation team was terrific. They worked hard, thought through some challenges, and in the end came up with a spectacular result. The connecting wires are largely hidden and those that were necessary are only visible if you look for them. We did not expect it to look so good. During the process there were some COVID delays and the team stepped up to mitigate them. As family and friends see our panels, I am steering them to ReVision Energy.

We're very pleased with our roof-mount solar array from 603 Solar. Their team was easy to communicate with throughout all stages of the project. When upgraded panels came onto the market, they updated the original layout design to best fit our roof and maximize wattage. 603 followed up after the install, ensuring that everything was in good working order and that we had access to the system monitoring app. Sean, Erin, and Zach were courteous and professional throughout. Highly recommend.

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.

We reached out to Greg at Harvey Woods to help us with a leak in our roof that had solar panels on it. We had lost our solar company, and we were floundering, as we were quoted $10,000 from several companies to remove the panels and put them back. Greg worked with our contractor to remove the panels, find and fix the leak, and put back the panels. He even added a fence around the panels to help keep the leak issue from happening again. Harvey Woods is now our solar company going forward.
