Thermal solar inspection in Montana
A thermal solar inspection uses infrared cameras to identify hidden faults in your solar system — hotspots, cell damage, wiring issues, and connection failures that are invisible to the naked eye. In Montana, where the climate is cold with 4.6 peak sun hours per day, thermal inspection is particularly valuable for systems over 5 years old.
What thermal inspection detects
Cell hotspots
Localised overheating in individual cells caused by micro-cracks, shading, or manufacturing defects. Best detected via thermal imaging.
Typical loss: 5–20%
Wiring or connection issues
Loose connectors, corroded terminals, or damaged wiring causing resistive losses. Can be a fire risk if severe.
Typical loss: 3–20%
Types of solar inspection in Montana
Drone thermal audit
A drone equipped with an infrared camera flies over your array, capturing thermal images of every panel. Best for large or hard-to-access systems.
Typical cost: $200–500
Handheld thermal scan
A technician uses a handheld infrared camera from ground level or roof access. More affordable for smaller systems.
Typical cost: $150–350
