Common issues in New Hampshire
Natural panel degradation
All solar panels lose efficiency over time at roughly 0.5–0.8% per year. Accelerated in extreme heat or poorly manufactured panels.
Typical loss: 3–15%

Solar inspection in New Hampshire: frequently asked questions
How much does a solar panel inspection cost in New Hampshire?+
A standard visual and electrical inspection in New Hampshire costs $199–$349. A full thermal imaging audit using drone or handheld FLIR cameras runs $299–$549 for a typical residential 5–10 kW system. Commercial inspections are quoted per kW and usually start around $0.04–$0.08/W.
How many solar inspection providers operate in New Hampshire?+
PanelAudit lists 1 thermal and drone inspection providers serving New Hampshire, mixing national networks with NH-licensed local operators. We track coverage across 3 New Hampshire cities — request 2–3 quotes to compare turnaround, drone vs handheld FLIR, and certifications.
What's the most common solar defect found in New Hampshire?+
NH's cold climate keeps panels cooler, but inverter efficiency loss and shading still drive 5–25% underperformance. Soiling risk in NH is low, and natural degradation averages 0.5%/year on quality panels — so a 10-year-old system should still be performing within 5% of nameplate after cleaning.
How often should New Hampshire solar owners get an inspection?+
Every 3–5 years is typical in NH with 3.8 peak sun hours. Always inspect after a hail event, major storm, or if monitoring shows a 8%+ year-on-year drop.
Are drone thermal inspections legal in New Hampshire?+
Yes. Commercial drone solar inspections in New Hampshire require an FAA Part 107 certified pilot, and most reputable NH providers fly DJI Matrice or Mavic 3T airframes with calibrated FLIR sensors. Flights stay below 400 ft AGL and require basic homeowner consent.
Will an inspection help with a New Hampshire warranty claim?+
Yes — most panel and inverter warranties require third-party diagnostic evidence (thermal images, IV-curve traces, or performance reports) before honouring claims. A $300–$500 inspection in New Hampshire often unlocks $2,000–$8,000 in covered repairs or panel replacements.
