ME's cold climate keeps panels cooler, but inverter efficiency loss and shading still drive 5–25% underperformance. Soiling risk in ME 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.

Every 3–5 years is typical in ME with 3.8 peak sun hours. Always inspect after a hail event, major storm, or if monitoring shows a 8%+ year-on-year drop.

Yes. Commercial drone solar inspections in Maine require an FAA Part 107 certified pilot, and most reputable ME providers fly DJI Matrice or Mavic 3T airframes with calibrated FLIR sensors. Flights stay below 400 ft AGL and require basic homeowner consent.

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 Maine often unlocks $2,000–$8,000 in covered repairs or panel replacements.
