IEC 61853-3-2018 pdf download.Photovoltaic (PV) module performance testing and energy rating – Part 3: Energy rating of PV modules.
This part of IEC 61853 describes the calculation of PV module energy rating values. IEC 61853-1 describes requirements for evaluating PV module performance at various temperatures and irradiances in terms of power (watts) rating. IEC 61853-2 describes test procedures for determining module temperature from irradiance, ambient temperature and wind speed, a method for measuring angle of incidence effects, and spectral responsivity. IEC 61853-4 describes the standard reference climatic profiles (standard environmental data sets) that are used for calculating energy rating values.
The purpose of this document is to define a methodology to determine the PV module energy output (watt-hours), and the climatic specific energy rating (dimensionless) for a complete year at maximum power operation for the reference climatic profile(s) given in IEC 61853-4. It is applied to determine a specific module output in a standard reference climatic profile for the purposes of comparison of rated modules.
The methodology does not take into account either progressive degradation or transient behaviour such as light induced changes and/or thermal annealing.
The present document applies to mono-facial modules.

3.1
climatic specific energy rating
CSER
normalised energy collection for the reference climatic profile, i.e. the ratio of the actual energy collection to that which would have been obtained if the PV module always performed with the energy conversion efficiency measured under standard test conditions
Note I to entry: CSER is dmensonIess
4 Testing
No testing is performed within this document: however, the energy rating calculations defined in Clause 7 use data from measurements made according to IEC 61853-1 and IEC 61853-2 and the standard reference climatic profiles from IEC 61853-4.
