Overview

EN IEC 61853-4:2018 - Photovoltaic (PV) module performance testing and energy rating - Part 4: Standard reference climatic profiles defines the standard reference climatic profiles used for calculating PV module energy ratings. It supplies standardized, hourly climatic data sets (provided as attached zip files) that represent typical irradiance, temperature and wind conditions for six global regions. These reference profiles are intended for use together with IEC 61853-1/2/3 methods to produce comparable energy ratings across PV technologies.

Key topics and requirements

• Purpose: Provide a fixed set of climatic inputs for energy rating calculations (used by IEC 61853-3).
• Number of profiles: Six standard reference climatic profiles representative of different global regions (tropical humid, subtropical arid, subtropical coastal, temperate coastal, high elevation, temperate continental). The table in the standard lists each profile with latitude and total yearly global in‑plane irradiance H_p (kWh/m2).
  • Example totals from the standard: Tropical humid (1°S) 1677.7 kWh/m2; Subtropical arid (33°30′N) 2295.5 kWh/m2; Temperate coastal (56°N) 972.9 kWh/m2; etc.
• Fixed mounting conditions: Open‑rack, free‑standing racks, equator‑facing orientation with a fixed inclination angle β = 20°.
• Data format and granularity: Hourly values for a full year (days 1–365). For each hour the data set includes:
  • Year, month, day, hour (local solar time)
  • Ambient temperature (T_amb)
  • Wind speed at module height (v)
  • Sun elevation and incidence angle (θ)
  • Global horizontal irradiance (G_h) and direct horizontal irradiance (B_h)
  • Global in‑plane irradiance (G_p) and direct in‑plane irradiance (B_p)
  • Spectrally resolved global in‑plane irradiance G(λ) in discrete bands (derived from satellite data)
• Use constraints: Climatic data are representative average conditions and do not account for progressive degradation or short‑term transient behaviors (e.g., light‑induced changes).

Applications and who uses it

• PV module manufacturers and test laboratories - to produce standardized energy ratings for datasheets and certification.
• Certification and conformity assessment bodies - to ensure consistent energy‑rating comparisons.
• System designers, engineers and energy modelers - to evaluate expected performance and compare module choices across climates.
• Researchers and policymakers - to benchmark technology performance and support policy or procurement specifications.
• PV project developers - for comparative yield assessments when site‑specific meteorological data are not used.

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 a
