Lightning test for concentrator photovoltaic system

This paper describes the results of the lightning test for CPV system. The CPV system is provided with a tracking device. For 14kW system, the entire aperture area is 75 m² and its height is approximately 10 m. This is relatively tall structure and subject to receive lightning damage. The IEC62305 standard describes the durability of CPV modules against lightning strike effect. Our test revealed that lightning current passed through the module´s aluminum chassis and flowed directly into the ground. Module IV measurement was performed, and no degradation or change was observer before and after the lightning test.
