European Network of PV Outdoor Testing – Steps towards Harmonized Procedures

Previous results of round-robin tests among European PV outdoor test facilities showed that the measurement agreement depends on the PV module technology. Pmax at STC matched within 2% for c-Si, 5% for CIS and CdTe based thin film technologies, and within 10% for a-Si based modules. To improve the accuracy and reliability of PV module outdoor performance characterization, harmonized procedures are formulated and implemented across PV outdoor...
