Proper maintenance is necessary for the safe and reliable functioning of long-term solar power generation systems for decarbonization. So conducting electrical testing on the system according to the international standard is important. This article discusses the DC side testing of the IEC 62446-1 standard.
As the solar photovoltaic (PV) industry rapidly matures, accurate performance testing becomes critical for validating system efficiency, securing investor confidence, and ensuring long-term returns.
This standard also describes DC testing of the PV system, which can also be used for periodic testing of the system. In the standard, the test is classified into categories 1 and 2 according to the size of the PV system. Category 1 applies to all solar PV generation systems.
