This method works by putting a special voltage on the photovoltaic cells when it is dark. The cells then give off a weak infrared light. You can see cracks, broken cells, and other problems that you cannot see with your eyes. . While the risk of electro-magnetic and/ or radar interference from PV systems is very low, it does merit evaluation, if only to improve the confidence of site owners and other stakeholders. With the growing presence of photovoltaic technology in electric power generation, there is a need to assess key modules of these systems for HEMP susceptibility. m test area fully encloses device. . Rapid expansion of solar photovoltaic (PV) installations worldwide has increased the importance of electromagnetic compatibility (EMC) of PV components and systems. These waves include radio waves, microwaves, infrared, visible light, ultraviolet rays, X-rays, gamma rays, and more, spanning a wide range of frequencies from low to high. Finding defects early protects your solar investment. The major emphasis has been given on the issues related to generate EMI magnitude due to PV panel capacitance to earth, Common Mode (CM) interference due to switching. .
