PD IEC TS 62257-9-6:2019

What is PD IEC TS 62257-9-6- Photovoltaic individual electrification systems about? 

PD IEC TS 62257 is an international standard that discusses renewable energy and hybrid systems for rural electrification. The IEC 62257 series intends to provide different players involved in rural electrification projects (such as project implementers, project contractors, project supervisors, installers, product suppliers, etc.) documents for setting up renewable energy and hybrid systems with a.c. voltage below 1 000 V and d.c. voltage below 1 500 V. 

PD IEC TS 62257-9-6 is one of the parts in a series of documents that specifies simple selection procedures 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. 

The tests provided in PD IEC TS 62257-9-6 allow assessment of the performance of PV-IES according to the requirement of the General Specification (GS) of the project and to verify their ability to provide the required service. They are performed locally, as close as possible to the real site operating conditions. 

Note: PD IEC TS 62257-9-6 is not a type of approval standard. It is a technical specification to be used as guidelines and does not replace any existing IEC standard on PV systems. 

Who is PD IEC TS 62257-9-6- Photovoltaic individual electrification systems for? 

PD IEC TS 62257-9-6 on photovoltaic individual electrification systems is relevant to: 

• Market support programs that support the off-grid lighting market with financing, consumer education, awareness, and other services 
• Manufacturers and distributors that need to verify the quality and performance of off-grid renewable energy product 
• Bulk procurement programs that facilitate or place large orders of products 
• Trade regulators such as government policymakers and officials who craft and implement trade and tax policy 
• Renewable energy organizations and institutions 
• Laboratories of developing countries 
• Regulatory bodies 

Why should you use PD IEC TS 62257-9-6- Photovoltaic individual electrification systems? 

Photovoltaic hybrid power systems are gaining attraction among rural electrification institutions as a way to reduce fuel price rises, produce lower operating costs, and provide improved service quality than traditional single-source generating systems. The combination of technologies opens up intriguing possibilities for overcoming technological limits. One of the main objectives of PD IEC TS 62257-9-6 is to provide minimum requirements relevant to renewable energy and hybrid off-grid power systems. 

PD IEC TS 62257-9-6 helps you identify the right system for the right place, so as to ensure operational efficiency while enabling cost-reduction with the best suitable design, installation and operation practices.  

What’s changed since the last update? 

PD IEC TS 62257-9-6:2019 supersedes DD IEC/TS 62257‑9‑6:2008, which is withdrawn. The main technical modifications are the following: 

• Removal of the term "small" from the title of the publication and from the description of rural electrification systems 
• Removal of the limits on system voltage and power; these recommendations apply to systems of all sizes
