Full title and description

IEC TS 61724-3:2016/COR1:2018 — Corrigendum 1 to "Photovoltaic system performance — Part 3: Energy evaluation method". This corrigendum publishes editorial and minor technical corrections to the 2016 Technical Specification that defines procedures for measuring and analysing the electrical energy production of a photovoltaic (PV) system and comparing measured energy with expected energy based on actual weather and system data.

Abstract

This one-page corrigendum (Corrigendum 1, February 2018) corrects and clarifies text in IEC TS 61724-3:2016. It addresses errors, clarifies wording and references, and refines minor formula/notation or cross‑reference issues so that the energy evaluation method described in the parent Technical Specification is unambiguous for implementers and test personnel.

General information

• Status: Published (corrigendum to IEC TS 61724-3:2016)
• Publication date: 14 February 2018
• Publisher: International Electrotechnical Commission (IEC), TC 82 — Solar photovoltaic energy systems

Scope

The corrigendum applies only to IEC TS 61724-3:2016. Its scope is limited to correcting editorial mistakes and making minor technical clarifications in the energy evaluation method (definitions, equations, references or notes) so that practitioners using the 2016 Technical Specification for PV energy yield assessment and availability calculations can apply the procedures without ambiguity.

Key topics and requirements

• Corrections and clarifications to the IEC TS 61724-3:2016 text to remove ambiguity.
• Refinement of definitions and notation used in the energy evaluation methodology.
• Adjustments or clarifications to formulas, tables or normative references where necessary.
• Ensures consistency with the monitoring and performance concepts used across the IEC 61724 series.
• Does not introduce major new technical requirements — it preserves the original intent of the 2016 Technical Specification while improving clarity.

Typical use and users

Used by PV performance engineers, test laboratories, project developers, asset owners/operators, performance auditors, researchers and policymakers who apply IEC TS 61724-3 procedures to evaluate measured energy against expected production. The corrigendum is consulted alongside the 2016 TS whenever precise wording, formulae or cross-references need confirmation.

Q: What does it cover?

A: It provides editorial and minor technical corrections to the 2016 Technical Specification so that the procedures, definitions and equations for comparing measured and expected PV energy are clearer and consistent.

Q: Who typically uses it?

A: PV performance engineers, test labs, asset owners/operators, performance auditors, consultants and researchers who apply IEC TS 61724-3 for energy evaluation and need to ensure they are using the corrected/clarified text.
