Photovoltaic devices - Measurement principles for terrestrial photovoltaic (PV) solar devices with reference spectral irradiance dataWhat is BS EN IEC 60904 3 about? BS EN IEC 60904 series discusses photovoltaic devices. BS EN IEC 60904 3 is the third part of a series of documents. Photovoltaic conversion is spectrally selective due to the nature of the semiconductor materials used in PV solar cells and modules. To compare the relative performance of different PV devices and materials a reference standard solar spectral distribution is necessary. BS EN IEC 60904 3 specifies a

boilers with a maximum pressure rating of 2 000 kPA (20 bar) and equipment for general household and similar use including controls for heating

These instructions are likely to differ between manufacturers according to the details of the equipment

and subsystem functional requirements

BS EN 60952-3 can be used as a framework to devise tests for the generation of the required data
