How a Thermal Scan Can Catch a Failed Panel Before Warranty Expires
Why an infrared inspection during a routine cleaning is often the only way to catch a silently failing panel in time.
Most panel failures are silent, production drifts slowly while the module overheats internally. A thermal scan during a routine cleaning is often the only way to catch it while the manufacturer warranty still applies.
What a failing panel looks like on thermal
A healthy panel reads as an even, uniform surface on an infrared camera. A failing module typically shows a distinct hot zone, sometimes a full panel running 20–40°F above its neighbors, sometimes a single cell or sub-string lit up against an otherwise cool background. Visual inspection from the ground almost never shows anything; the failure is internal.
Filing a warranty claim with documentation
Cleaning instructions and warranty terms vary by panel model. Check your module's manual before choosing water quality, products, brushes, or pressure. We use deionized water and solar-specific brushes without soaps or harsh abrasives. Warranty decisions belong to the manufacturer, not the cleaning company.
Why timing matters
Replacing a single residential panel out of pocket, module plus labor, typically runs several hundred to over a thousand dollars depending on access. A thermal scan included with a routine cleaning costs nothing extra, and it's the difference between a warranty replacement and an out-of-warranty repair if the panel fully fails later.
