Solar modules are sold based on performance categories. Therefore, the precise performance measurement of modules is of critical importance. The sun simulators used for power measurement are classified into different accuracy classes according to their performance.
The IEC Standard IEC 60904-9 classifies sun simulators into the three classes A (the best), B and C, depending on three parameters.
The Pasan DragonBack® method facilitates highest-accuracy measurements of high-efficiency modules (e.g. HJT technology) with lowest TCO.
