Overview

This International Standard specifies procedures for on-site measurement of flat-plate photovoltaic (PV) array characteristics, the accompanying meteorological conditions, and use of these for translating to standard test conditions (STC) or other selected conditions. The measurement of current-voltage characteristics can provide the following information: - data for power rating or capacity testing; - verification of installed array power performance relative to design specifications; - detection of possible differences between on-site module characteristics and laboratory or factory measurements; - detection of possible performance degradation of modules and arrays with respect to onsite initial data; - detection of possible module or array failures or poor performance. Thus this standard provides information on the requirements for batteries for photovoltaic (PV) solar energy systems and for typical test methods to demonstrate battery performance. The responsible committee is K 373 "Photovoltaische Solarenergie-Systeme" ("Solar photovoltaic energy systems") of the DKE (German Commission for Electrical, Electronic and Information Technologies) at DIN and VDE.
