EVS-EN 61724:2002

This International standard recommends procedures for the monitoring of energy-related PV system characteristics such as in-plane irradiance, array output, storage input and output, and power conditioner input and output, and for the exchange and analysis of monitored data. The purpose of these procedures is to assess the overall performance of PV systems configured as stand-alone or utility grid-connected, or as hybridised with non-PV power sources such as engine generators and wind turbines. This standard may not be applicable to small stand-alone systems due to the relatively high cost of the measurement equipment.
