Infrared Inspection Of Solar Panels

Handheld thermal imaging cameras for predictive maintenance inspections typically have an uncooled microbolometer detector sensitive in the 8 14 μm waveband.

Infrared inspection of solar panels. Infrared testing inc iti is merging its thermal imaging expertise with cutting edge drone technology to find the problems changing the process of inspecting solar energy systems. Scanpro conducts a mixture of ground based infrared thermal imaging and uav drone surveys. At night if a panel is pointed toward earth then it could capture the earth s invisible infrared light. Thermographic inspection of photovoltaic installations.

Detection of a wide range of local faults and irregularities. At this particular solar field infrared testing inc. Measure solar radiation with an appropriate light meter to make sure that the solar radiation is at or above 650 w m. Iti s custom drones seize complete data in order to classify identify and localize each anomaly and understand the impact of its performance on the system.

The use of uav s during inspections allows us to position the thermal imaging camera at the correct angle to the glass surface for accurate results. Infrared solar panel inspection detects hot cells in photo voltaic arrays. Defective cells like this will reduce the power output of the panel. Drones provided with infrared cameras are transforming how the solar systems are inspected and maintained.

For good thermography inspections select a clear dry day. In direct sunlight solar panels work at full capacity and damaged solar cells will show clearly on the infrared image. An infrared camera helps to visualise defects on new and existing installations. Infrared solar cells will boost solar power by up to 25 and eventually double brian wang november 2 2019 a research team led by hans ågren professor in theoretical chemistry at kth royal institute of technology has developed a film that can be applied on top of ordinary solar cells which would enable them to use infrared light in.

Visualisation allows initial on site evaluation. This infrared image from an inspection of a solar pv panel shows a single defective cell which is overheated. 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. When solar cells are inspected from the front a thermal imaging camera sees the heat distribution on the glass surface.

The paper claims an anti solar. Hot pv cells reduce efficiency and can cause panel failure. It also allows us to cover more area and remain in a safe position. Iti a chicago based thermographic testing company brought in a custom drone equipped with high resolution digital and infrared cameras and.
