With each new module generation, we see more energy generated at lower costs. This trend looks set to accelerate with the development of high-efficiency cells such as TOPCon products. Module performance characteristics, provided by manufacturers in “PAN files,” are improving and it seems that this is only the beginning. While everyone wants to hear that their project is going to perform brilliantly, developers should take a balanced approach to manufacturers’ claims and cross check against sound data to make sure that “Peter-Pan” files do not turn projects into PV pandemonium.
The same product, tested by different laboratories, may return differing characteristics. The reason for this is the accuracy of the test equipment, which will vary from one test site to another.
