Derry, New Hampshire, is a rapidly growing suburban town with a strong commitment to renewable energy. The town has seen a significant increase in residential solar installations over the past three years, driven by rising electricity costs from Eversource and state incentives like net metering. The market is competitive but still underserved: many homeowners in Derry are looking for reliable local installers rather than large out‑of‑state companies. Key demand drivers include the federal Investment Tax Credit (ITC) at 30%, New Hampshire’s Renewable Energy Fund rebates, and the increasing awareness of energy independence. The average residential system size in Derry is around 8–10 kW, with payback periods of 8–12 years. Commercial and municipal solar is also growing, especially for farms and small businesses. To succeed, you need to position yourself as a trusted local expert who understands Derry’s specific zoning, tree coverage, and roof orientations.
New Hampshire does not have a statewide solar installer license. Instead, you must hold a valid New Hampshire Electrician’s License (Master or Journeyman) issued by the New Hampshire Board of Electricians. If you install panels yourself, you need at least a Journeyman license working under a Master. Many solar businesses partner with a licensed electrician or hire one full‑time. You also need a business license from the New Hampshire Secretary of State and a local business permit from the Town of Derry. Check with Derry’s Town Clerk for any additional home occupation or contractor registration requirements.
All solar installations in Derry require a building permit from the Town of Derry Building Department. You must submit structural calculations, electrical diagrams, and site plans. The town follows the 2020 New Hampshire State Building Code with local amendments. After installation, inspections are required by both the building inspector and the electrical inspector. Additionally, you need to coordinate with Eversource for net metering interconnection. Submit an interconnection application before starting work. Utility approval typically takes 4–6 weeks.
Carry general liability insurance (minimum $1 million) and workers’ compensation insurance (required by NH RSA 281‑A if you have employees). Many Derry homeowners also ask for proof of bond or performance guarantees. The New Hampshire Department of Energy provides a list of approved renewable energy contractors, which can help build credibility.
