Common issues in Louisiana

Cell hotspots

Localised overheating in individual cells caused by micro-cracks, shading, or manufacturing defects. Best detected via thermal imaging.

Typical loss: 520%

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: 315%

Solar inspection in Louisiana: frequently asked questions

How much does a solar panel inspection cost in Louisiana?+

A standard visual and electrical inspection in Louisiana 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 Louisiana?+

PanelAudit lists 4 thermal and drone inspection providers serving Louisiana, mixing national networks with LA-licensed local operators. We track coverage across 4 Louisiana cities — request 2–3 quotes to compare turnaround, drone vs handheld FLIR, and certifications.

What's the most common solar defect found in Louisiana?+

LA's hot humid climate accelerates panel degradation, with cell hotspots typically causing 5–20% output loss. Soiling risk in LA is moderate, 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 Louisiana solar owners get an inspection?+

Every 3–5 years is typical in LA with 4.9 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 Louisiana?+

Yes. Commercial drone solar inspections in Louisiana require an FAA Part 107 certified pilot, and most reputable LA 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 Louisiana 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 Louisiana often unlocks $2,000–$8,000 in covered repairs or panel replacements.
