Get answers to common questions about home solar services in Nashua, New Hampshire.
For a typical 6-8 kW system in Nashua, the gross cost before incentives ranges from $18,000 to $28,000. Crucially, you can significantly reduce this with the 30% federal Investment Tax Credit (ITC) and New Hampshire's own incentive: the $1,000 rebate for systems under 25 kW from the NH Public Utilities Commission. Additionally, you benefit from net metering with Eversource, and Nashua property owners receive a 100% property tax exemption for the added value of the solar installation.
Solar panels are very effective in New Hampshire's climate. They generate power from daylight, not heat, and actually operate more efficiently in cooler temperatures. Snow will temporarily reduce output, but panels are installed at an angle so snow often slides off, and dark panels absorb heat to help melt it. Your system is designed based on Nashua's historical sun data (about 4.5 peak sun hours daily on average) to produce ample annual energy, with summer overproduction offsetting lower winter yields through net metering.
A reputable local installer will handle the entire permitting process for you. This includes securing an electrical permit from the City of Nashua Building Division and ensuring compliance with the New Hampshire State Electrical Code. They will also submit an Interconnection Agreement to Eversource, your local utility, to connect your system to the grid for net metering. Most residential installations in Nashua do not require special zoning variances if mounted on a roof.
Prioritize installers who are locally established, licensed in New Hampshire, and have extensive experience with Nashua's specific permitting and interconnection processes. Look for strong warranties (25-year on panels, 10+ years on workmanship) and check reviews on local platforms. It's essential to get multiple detailed quotes that explain equipment choices, projected production specific to your roof's orientation, and a clear breakdown of all costs and savings.
New Hampshire law mandates net metering. With Eversource, your solar production first powers your home; excess is sent to the grid, spinning your meter backward and earning you a kilowatt-hour (kWh) credit. At night or during low production, you use credits from the grid. Credits roll over monthly, with an annual "settlement" where you may receive a payment for small excesses. Importantly, standard grid-tied systems shut off during a power outage for safety unless paired with a dedicated battery backup system, which is a popular add-on in Nashua for resilience.
