Get answers to common questions about home solar services in Grantham, New Hampshire.
While Grantham experiences significant snowfall and shorter winter days, modern solar panels are efficient at converting indirect light and perform well in cold, sunny weather. Snow typically slides off angled panels, and winter production, though lower, is offset by high summer output. Proper system sizing by a local installer accounts for these seasonal variations to ensure your annual energy needs are met.
The gross cost for a typical residential system in New Hampshire ranges from $15,000 to $25,000 before incentives. Grantham homeowners benefit from the 30% federal tax credit, a state property tax exemption for the added home value, and net metering with your utility (like Liberty Utilities or Eversource). Many local installers offer financing, including loans and leases, to make the upfront cost manageable.
Yes, you will need a building permit from the Grantham Town Office. New Hampshire has a state-wide "right-to-install" solar law that prevents unreasonable restrictions from homeowners' associations. Your chosen installer will typically manage the entire permitting process, including interconnection approval with your utility, ensuring compliance with all local and state codes.
Look for established, local New Hampshire or Upper Valley installers with strong Grantham references. Verify they are licensed (NH Electrician's License), insured, and certified by manufacturers like SunPower or Tesla. A trustworthy provider will conduct a detailed, on-site assessment of your roof, shading, and energy use to provide a transparent, customized proposal without high-pressure sales tactics.
Standard grid-tied solar systems automatically shut off during a grid outage for safety. To have backup power, you must install a solar battery storage system (like a Tesla Powerwall). This is a particularly valuable consideration in Grantham, where winter storms can cause outages. Many local installers now offer integrated solar-plus-battery solutions to provide essential circuit backup.
