To investigate the performance loss of a PV power plant, we offer a comprehensive failure diagnosis of the entire power plant.
Among other devices, we use a mobile electroluminescence measuring system that can be operated on-site to determine the module performance, either in the sunshine or in the dark. The "DaySy" measuring system (Daylight Luminescence System) allows fast and reliable measurement and documentation of module damage:
- measurement of complete strings on site, no de-mounting of the modules required
- measurement independent of ambient light, power supply by solar power of the power plant or DC generator
- measurement of modules and PV strings with up to 1000 V and 10 A
