What Is a Home Solar Panel Installation
Cold Air, Clear Skies and Productive Panels
Rooftop panels turn sunlight into electricity, and an inverter feeds it into your home. Cold, clear days are surprisingly good for solar, because panels run more efficiently at low temperatures.
Your household uses that power first, and any surplus goes to the grid for credit through New Hampshire net metering with Eversource or the utility serving your street. The system runs without your input and is built to last 25 years or more.

Solar in the Hometown of Robert Frost
Protecting the Woods and Fields Around Derry
Derry’s farms, forests and ponds inspired one of America’s best known poets. Producing clean energy at home helps keep that landscape healthy.
A typical home solar system in southern New Hampshire can produce roughly 7,000 to 9,000 kilowatt hours of clean electricity a year. That is power New England does not need to generate from natural gas plants on the coldest, busiest days.
From Beaver Lake to the stone walls along the back roads, Derry’s character depends on clean air and water. Each solar roof in town is a small, steady step toward a cleaner New Hampshire.

Frequently Asked Questions
What Derry Homeowners Want to Know About Solar
These questions come up in almost every solar conversation we have in Derry.
What happens to my panels when they are covered in snow?
Production pauses until the snow slides off, which usually happens within a day or two of sun on a tilted roof. We size your system on a full year of output, so winter dips are already built in.
Does New Hampshire offer a state solar tax credit?
No. New Hampshire has no broad state income tax, so there is no state solar credit. The state does have no sales tax, net metering and a local option property tax exemption that many towns have adopted.
Has Derry adopted the solar property tax exemption?
New Hampshire lets each town vote on whether to exempt solar from property tax. We confirm Derry’s current status for you and file the exemption form if it applies.
How does Eversource credit my extra power?
When your panels produce more than you use, the surplus is credited on your bill under New Hampshire net metering. Credit values vary by utility and tariff, so we size systems to match your real usage.
Is there a federal credit for homeowners this year?
The 30% federal residential credit for homeowner owned systems ended on December 31, 2025. Lease and power purchase options may still carry federal benefits through the provider.
