This standard BS EN 62124:2005 Photovoltaic (PV) stand-alone systems. Design verification is classified in these ICS categories:
27.160 Solar energy engineering
Verifies system design and performance of stand-alone photovoltaic systems. The performance test consists of a check of the functionality, the autonomy and ability to recover after periods of low state-of-charge of the battery, and hence gives reasonable assurance that the system will not fail prematurely. The testing conditions are intended to represent the majority of climatic zones for which these systems are designed.
