Yes. Most Louisville thermal inspection providers use FLIR-equipped drones that fly the array at 15–25m altitude and identify cells running 10°C+ hotter than neighbours. This is the most reliable way to detect micro-cracks, bypass diode failure, and cell-level hotspots without panel removal.

Yes — most panel and inverter warranties in Kentucky require third-party diagnostic evidence (thermal images, IV curves, or performance reports) before honouring claims. A $300–$500 inspection often unlocks $2,000–$8,000 in covered repairs or panel replacements.
