Overview - EN IEC 61853-3:2018 (Photovoltaic module energy rating)

EN IEC 61853-3:2018 specifies the calculation methodology for the energy rating of photovoltaic (PV) modules. It defines how to determine a module’s annual energy output (watt‑hours) and the climatic specific energy rating (a dimensionless number) for a full year of maximum‑power operation using the standard reference climatic profiles given in IEC 61853-4. The standard is intended for mono‑facial PV modules and is used to produce comparable, standardized module energy outputs for product comparison and rating.

Key topics and technical requirements

• Energy rating calculation methodology: Stepwise procedure to convert environmental data and module test inputs into hourly, annual and specific energy outputs.
• Required input data: Module performance versus irradiance and temperature, spectral responsivity, incidence angle behaviour and module operating temperature estimates (data typically derived from IEC 61853-1 and IEC 61853-2 tests).
• Reference climates: Use of standard reference climatic profiles from IEC 61853-4 to ensure consistent, comparable energy ratings.
• Corrections and adjustments:
  • In‑plane global irradiance corrected for angular incidence effects.
  • Spectral correction of in‑plane irradiance using measured spectral responsivity.
  • Calculation of module temperature from irradiance, ambient temperature and wind speed.
• Power and energy computation: Determination of instantaneous module power at maximum power point, hourly energy outputs, and aggregation to annual energy output (watt‑hours).
• Limitations: The methodology does not account for progressive degradation, or transient effects such as light‑induced changes and thermal annealing.

Applications - who uses EN IEC 61853-3 and why

• PV module manufacturers: For publishing standardized energy ratings and product datasheets that enable fair market comparison.
• Test laboratories and certification bodies: To produce reproducible energy rating reports for certification, compliance checks and third‑party verification.
• PV system designers and asset owners: To compare module energy yields under defined reference climates when selecting modules for projects and procurement.
• R&D and performance analysts: To benchmark technology performance across spectral, angular and temperature variations. Practical uses include energy yield comparisons, procurement specifications, pre‑sale performance claims, and standardized inputs for system energy models.

FOREWORD
1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of IEC is to promote
international co-operation on all questions concerning standardization in the electrical and electronic fields. To
this end and in addition to other activities, IEC publishes International Standards, Technical Specifications,
Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC
Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested
in the subject dealt with may participate in this preparatory work. International, governmental and
non-governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates
closely with the International Organization for Standardization (ISO) in accordance with conditions determined
by agreement between the two organizations.
2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
consensus of opinion on the relevant subjects since each technical committee has representation from all
interested IEC National Committees.
3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
misinterpretation by any end user.
4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
transparently to the maximum extent possible in their national and regional publications. Any divergence
between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in
the latter.
5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity
assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
services carried out by independent certification bodies.
6) All users should ensure that they have the latest edition of this publication.
7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
members of its technical committees and IEC National Committees for any personal injury, property damage or
other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC
Publications.

INTRODUCTION
This International Standard series establishes IEC requirements for determining PV module
performance in terms of power (watts), specific module energy rating (kWh/kW) and climatic
specific energy rating (dimensionless). It is written to be applicable to all PV technologies
including non-linear devices. The methodology does not take into account either progressive
degradation or transient behaviour such as light induced changes and/or thermal annealing.
This series consists of four parts:
• IEC 61853-1: Photovoltaic (PV) module performance testing and energy rating – Part 1:
Irradiance and temperature performance measurements and power rating, which describes
requirements for evaluating PV module performance in terms of power (watts) rating over
a range of irradiances and temperatures;
• IEC 61853-2: Photovoltaic (PV) module performance testing and energy rating – Part 2:
Spectral responsivity, incidence angle, and module operating temperature measurements,
which describes test procedures for measuring the effect of varying angles of incidence
and sunlight spectra as well as the estimation of module temperature from irradiance,
ambient temperature, and wind speed;
• IEC 61853-3: Photovoltaic (PV) module performance testing and energy rating – Part 3:
Energy rating of PV modules, which describes the calculations for PV module ratings; and
• IEC 61853-4: Photovoltaic (PV) module performance testing and energy rating – Part 4:
Standard reference climatic profiles, which describes the standard time periods and
environmental data set that shall be used for the energy rating calculations.
