The competition is among established, reputable companies rather than a high volume of smaller, newer entrants. Homeowners can expect a premium level of service and expertise. Typical pricing for a residential system is competitive with the national average, ranging from **$3.00 to $3.80 per watt** before federal and state incentives, with the final cost heavily dependent on system size, equipment choice, and roof complexity.

Get answers to common questions about home solar services in New Castle, New Hampshire.
New Castle's coastal location provides excellent summer sun but introduces seasonal considerations. While winter snow can temporarily reduce production, panels often shed snow quickly on sloped roofs, and the cold temperatures actually improve panel efficiency. The key is proper system sizing by a local installer who understands our specific solar irradiance patterns, ensuring your system generates ample power year-round, even with shorter winter days.
After the 30% federal tax credit, a typical New Castle home solar system costs between $15,000 and $25,000. New Hampshire offers additional incentives, including a state rebate of $0.20 per watt (up to $1,000) and property tax exemption for the added system value. With New Hampshire's high electricity rates (around 22¢/kWh for Eversource) and net metering, most homeowners see a payback period of 8-12 years on a system designed to last 25+ years.
Yes, this is critical. New Castle is a historic seacoast town with strict zoning and aesthetic guidelines. If your home is within a historic district or is a designated historic property, you will need approval from the New Castle Historic District Commission. A reputable local installer will be familiar with this process and can help design a system that meets both energy goals and local preservation standards.
Prioritize providers with extensive experience in the Seacoast NH area and specific knowledge of New Castle's permitting process. Look for local, licensed, and insured installers with strong references. Your quotes should include a detailed production estimate specific to your roof's orientation, a clear breakdown of all costs, warranty information (25-year panel performance is standard), and their plan for handling local interconnection with Eversource and any historic review.
New Hampshire has a robust net metering policy. When your panels produce more electricity than your home uses (common on sunny summer days), the excess is sent to the grid, and your utility (like Eversource) credits your account. These credits roll over month-to-month and can be used to offset your consumption during less sunny periods, like at night or in the winter. This "virtual battery" makes solar highly effective and eliminates waste.
