Infrared inspections of roof and ground mounted photovoltaic solar electric generation systems identify defective cells within panels loose combiner box wire connections faulty fuses defective breakers damaged switches overloaded or imbalanced circuits and a myriad of other problematic electrical conditions read more.
Efficient method for detection of power losses.
This infrared image from an inspection of a solar pv panel shows a single defective cell which is overheated.
For good thermography inspections select a clear dry day.
Handheld thermal imaging cameras for predictive maintenance inspections typically have an uncooled microbolometer detector sensitive in the 8 14 μm waveband.
Defective cells like this will reduce the power output of the panel.
Measure solar radiation with an appropriate light meter to make sure that the solar radiation is at or above 650 w m.
