For homeowners in New Hampshire, investing in solar panels or a battery backup system is more affordable than you might think. With a mix of utility programs, billing incentives, and tax benefits, there are several ways to lower upfront costs.
Here’s a closer look at some of the top programs that can help you save while making your home more energy efficient.
Eversource Energy’s Demand Response Program
If you’re an Eversource customer, their Demand Response Program offers two valuable ways to offset the cost of installing a home battery system.
During the summer months, typically from June 1 through September 30, electricity demand spikes due to increased air conditioning use. By enrolling your battery in the program, you allow the grid to draw a portion of your stored solar energy during these peak periods, while still maintaining backup power for your home.
Battery Rebate
Homeowners can receive an upfront incentive to help cover the cost of installing a battery system. In exchange, up to 20% of your stored energy may be used during peak demand events.
ConnectedSolutions Battery Incentive
In addition to the upfront rebate, you can earn ongoing payments based on how much energy your system contributes during these events. Eversource Energy offers $225 per kW of contributed capacity, and a typical home battery system can earn up to $1,125 per year.
Net Metering
When your system produces more electricity than your home uses, the excess energy is sent back to the grid in exchange for credits on your utility bill.
In New Hampshire, net metering is available through utilities including Eversource Energy, Liberty Utilities, New Hampshire Electric Cooperative, and Unitil. For a deeper look at how credits are calculated, check out our guide on net metering in New Hampshire.
Credit rates and specific terms vary by utility, so it’s worth checking with your provider. For most solar homeowners, net metering is the single biggest factor in their return on investment – your panels are working for you even when you’re not home using electricity.
New Hampshire’s Property Tax Exemption
Installing solar doesn’t just reduce your energy bills and your footprint, it can also increase your home’s value. Luckily in New Hampshire, this added value won’t increase your property taxes thanks to RSA 72:62, the state’s solar energy property tax exemption. To take advantage of this exemption, be sure to file Form PA-29 after your system is installed.
The Federal Solar Investment Tax Credit (ITC)
The federal Investment Tax Credit is still one of the biggest financial incentives for going solar. As of 2025, homeowners can claim 30% of their total solar installation costs as a credit on their federal income taxes. That includes panels, battery systems, inverters, and installation labor.
This is a dollar-for-dollar credit against what you owe, not just a deduction. If your system costs $30,000, that’s a $9,000 tax credit. For homeowners who owe enough in federal taxes, this alone can change the payback timeline on a solar investment significantly.

FAQ
How much can I save by going solar in New Hampshire?
Savings depend on your roof, energy usage, and which incentives you qualify for. Between the 30% federal tax credit, Eversource’s demand response payments, net metering credits, and the property tax exemption, many homeowners recoup a large share of their investment within the first several years.
Do I need a battery to go solar in New Hampshire?
No. You can install solar panels without a battery and still take advantage of net metering, the federal tax credit, and the property tax exemption. Adding a battery gives you backup power during outages and qualifies you for Eversource’s demand response payments, but it’s not a requirement.
What is Form PA-29 and when do I need to file it?
Form PA-29 is the application for New Hampshire’s solar property tax exemption. File it with your local assessor’s office after your system is installed. Without it, your property could be reassessed at a higher value because of the solar installation.
Is Eversource the only utility that offers battery incentives in NH?
Eversource’s Demand Response Program is currently the most established battery incentive in New Hampshire. Other utilities offer net metering, but battery-specific rebates and payments vary. Contact your utility directly to ask what’s available in your area.
