This part of the IEC 62257 series introduces the entire series regarding off-grid renewable energy and hybrid products and systems most commonly used for rural applications and access to electricity.
This Part 1 00 document provides a guide for facilitating the reading and the use of the IEC 62257 series for setting up off-grid electrification in developing countries or in developed countries, the only difference being the level of service and the needed quantity of energy that the customer can afford.
This Part 1 00 document introduces the series. It focuses on the planned document organization and numbering structure, including a description of each topic and subtopic grouping. It contains a brief overview of the project management and tendering process.
It also contains a brief overview of the concept of “access to electricity” and some of the types of renewable energy off-grid and hybrid systems. This document has several examples of case studies for various user groups, to assist them in utilizing the updated series. Additionally, it contains an informative Annex A to assist users of prior versions of the IEC 62257-x series in locating content within the updated IEC 62257-xxx series.
This document outlines the organization of documents within the updated IEC 62257-xxx series published in 2022 and later, including utilization of a new 3-digit part numbering scheme, grouped into topics and subtopics. This series is anticipated to be of interest to the following renewable energy off-grid and hybrid system stakeholders:
• manufacturers
• testing and certification labs
• equipment distributors, importers, and bulk buyers
• government regulators, inspection, certification, safety, customs and trade agencies
• agencies developing regional-level solar lantern / kit programs
• agencies developing RFQs (Request for Quotations) for systems
• system designers, engineers, project implementers, contractors, supervisors
• installers of small PV and storage
• installers of small wind systems
• installers of large hybrid systems with multiple users
• system owners, residents, operators, maintenance personnel.
The document part numbers to be assigned within this updated IEC 62257-xxx series will be grouped into topics as follows:
• Parts -1 xx: Introduction and project management
• Parts -2xx: System design and installation
• Parts -3xx: Energy system components
• Parts -4xx: User equipment and appliances
• Parts -5xx: Stand-alone products and packaged kits.
To assist users in navigating the documents within the revised IEC 62257 series, this introductory -1 00 document presents how the documents will be further organized into the following subtopics, see Table 1 .
