Summary of New Hampshire solar incentives 2022
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.

Federal solar investment tax credit
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.
Net energy metering in New Hampshire
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.
New Hampshire solar rebates
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.
Property tax incentive
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.

All Energy Solar won Me over after I did months of research on all the nitty-gritty of how solar operated and what components preformed what functions by listening to what I wanted and understanding that they needed to provide me with exactly what wanted my system to comprise of. Molly (Sales) spent hours, multiple phone calls and 3-4 redesigns of my particular project. My solar battery backup (images) had to meet a minimum standard of backup and generation, while fitting into a specific wall space. Once we determined my project was able to be accomplished, we transitioned to Carlo (Project Manager) who took the rains of making my project a reality. Once the Electricians who performed the installation arrived (don't know if they want to be named) they adapted to my specific requirements (wiring / backup) and overcame limitations of available space. (Images) And finally, Murphy's Law would happen when (1 of 70ish) components malfunctiond. Carlo remained in contact with me constantly throughout my project from inception to paperwork to Installation to correction or equipment to closeout. Molly was still in contact at all times after her portion of my project was complete and available to assist with ensuing quality of service was upheld. I'm a Veteran who has been a Project Manager overseas and has delt with Contractors and frankly, slimy individuals who just care about the money. This company never gave me a reason to question them and I never felt as if I couldn't walk away at anytime. (Especially the legal contract paperwork part. Other companies I dealt with previously for solar installation options wanted signatures and legal binding contracts prior to discussion of what I actually wanted and ensuring I would get it the way I wanted it.) I endorse business with this company, because I got precisely what I wanted and how / where I wanted it and for my intended purpose.

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.

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.
