Get answers to common questions about home solar services in Portsmouth, New Hampshire.
For a typical 6-8 kW system in Portsmouth, the gross cost before incentives ranges from $18,000 to $28,000. Critically, you can reduce this by 30% with the federal Investment Tax Credit (ITC). New Hampshire also offers a specific property tax exemption, ensuring your home's assessed value won't increase due to the solar installation, and you may benefit from net metering with Eversource to earn credits for excess energy.
Solar panels are very effective year-round in New Hampshire. They generate electricity from daylight, not just direct sun, and cold temperatures actually improve panel efficiency. Snow typically melts quickly off the dark, slick panels, and any temporary coverage has a minimal annual impact. Your system will produce less in December but overcompensates with high output in the spring, summer, and fall, leading to substantial annual savings.
Installation requires a building permit from the City of Portsmouth's Inspection Department. If your home is in a historic district or has a historic designation, you will need additional approval from the Historic District Commission, which reviews proposals for visual compatibility. Your qualified local installer will typically manage this entire permitting process, including interconnection paperwork with utility provider Eversource.
Prioritize installers who are locally established, licensed, and insured in New Hampshire. Look for certifications like NABCEP (North American Board of Certified Energy Practitioners) and ask for multiple Portsmouth-specific references. A trustworthy provider will conduct a detailed site assessment, explain how Portsmouth's weather and your roof's orientation affect production, and provide a clear, detailed contract without high-pressure sales tactics.
Going completely off-grid in Portsmouth is technically possible but generally not practical or cost-effective for most homeowners due to our climate. It would require a very large and expensive battery bank to store enough energy for prolonged cloudy or snowy periods in winter. Staying connected to Eversource via net metering acts as a reliable "battery," providing power when needed and crediting you when you overproduce, which is the most common and economical approach.
