New Hampshire residents face high utility costs and long, dark winters — but solar still delivers real value. Thanks to net metering, state rebates, and modern technology that works well in snowy conditions, more Granite Staters are choosing solar to take control of their energy future. It’s a smart way to reduce bills while contributing to a cleaner, more resilient grid.
Choosing the right installer matters just as much as choosing to go solar in the first place — the difference between a company that’s licensed, experienced with New Hampshire’s NEM 2.0 net metering tariff, and backed by a real workmanship warranty and one that isn’t can add up to thousands of dollars over the life of your system. Below, you’ll find New Hampshire’s solar companies compared side by side, including which ones have completed EnergyScout’s verification process, so you can start your search with a shorter, more confident list.
EnergyScout tracks local and national solar companies serving homeowners throughout the state. Use the directory below to compare installers based on experience, service area, products, certifications, and other company information.
Companies displaying the EnergyScout Verified badge have completed an additional review process that includes a direct interview, screening customer feedback, and providing evidence of completed installations. Verification provides another layer of information when comparing solar companies, but homeowners should still evaluate multiple installers to find the right fit for their home.

New Hampshire’s Solar Market:
New Hampshire ranks #25 in residential solar installations with over 300 MW of total capacity. The state generates about 2% of its electricity from solar, with strong growth in recent years. New Hampshire employs over 1,100 solar workers, with mature installer networks across Manchester, Nashua, Concord, Portsmouth, and rural communities. While New Hampshire doesn’t get abundant sunshine compared to southwestern states, solar panels still perform well thanks to long summer days and cold temperatures that improve panel efficiency.
High Electricity Costs and Strong Incentives:
New Hampshire has some of the highest electricity rates in New England, often exceeding $0.20-$0.24 per kWh, making every kilowatt-hour of solar production extremely valuable. The state offers the Residential Renewable Energy Rebate program, providing upfront rebates for solar installations (subject to funding availability). New Hampshire also has strong net metering rules, allowing homeowners to earn credits at full retail rates when their systems produce excess energy. The state provides property tax exemption for solar installations. With high electricity rates and strong incentives, New Hampshire solar systems typically achieve payback within 9-13 years.
New England Weather Performance:
New Hampshire experiences harsh winters with heavy snow, cold temperatures, and shorter days. Solar panels actually perform more efficiently in cold weather — they lose efficiency in extreme heat, not cold. The challenge is snow accumulation and shorter winter days, but New Hampshire’s long summer days (15+ hours of sunlight) provide excellent production when the sun is high. The state also experiences nor’easters, ice storms, and occasional hurricanes that can cause extended power outages. Solar + battery systems provide critical energy security during grid failures. For New Hampshire homeowners tired of paying premium electricity rates and vulnerable to winter storm outages, solar offers both financial relief and energy independence.
