The purpose of this part of IEC 62257 is to propose simple selection procedure and cheap, comparative tests which can be performed in laboratories of developing countries, in order to identify the most suitable model of Photovoltaic Individual Electrification Systems (PV-IES) up to 500 Wp for a particular rural electrification project from a number of products submitted for test.

It is different from the scope of IEC 62124, Photovoltaic (PV) stand alone systems – Designverification, which provides guidance for verifying the design of stand-alone PV systems and indoor and outdoor tests in order to evaluate the performance of PV systems including PV generator, battery storage and loads such as lights, TV sets, and refrigerators.

The tests provided in this document allow assessment of the performance of PV-IES according to the requirement of the General Specification (GS) of the project (see IEC TS 62257-2) and to verify their ability to provide the required service. They are performed locally, as close as possible to the real site operating conditions.

This document is not a type approval standard. It is a technical specification to be used as guidelines and does not replace any existing IEC standard on PV systems.Cross References:IEC TS 62257-2:2015IEC TS 62257-8-1:2018IEC TS 62257-9-4IEC TS 62257-9-3IEC TS 62257-6IEC TS 62257-4IEC 61730-2IEC TS 62257-12-1IEC TS 62257-7-1IEC 61730-1IEC 61215 (all parts) IEC TS 62257-5IEC 62124IEC 62262IEC 60529IEC TS 61836
