4 For Comments Only DRAFT Indian Standard on SOLAR PHOTO VOLTAIC WATER PUMPING SYSTEMS Part 1 CENTRIFUGAL PUMPS SPECIFICATION (Modified draft based on the discussions in Panel Meeting on at Coimbatore) ICS ; Not to be reproduced without the permission of BIS or to be used as a Standard Last date for receipt of comments: FOREWORD (Adoption clauses to be added later on). This standard is primarily intended to introduce constructional, design, performance, safety features and testing requirements for Solar Photo Voltaic Water Pumping Systems and prescribes the method of measurement of performance & energy efficiency rating and testing for performance. While preparing this standard assistance has been drawn from Indian standards and guidelines as listed below: a) IS 9079: 2002 b) IS 14220: 1994 c) IS 8034: 2002 d) IS 9283: 2013 e) IS 14286: 2010 The manufacturers of solar powered water pump set offer an array of equipment to meet the diverse applications of markets. The complexity of the product offering precludes the testing of each and every model. However, to promote consistency in the representation of Solar powered water pump set performance by all manufacturers, this standard establishes uniform rating and testing methods. It is intended that equipment testing will be done in laboratory where the instrumentation and load stability as defined in the standard can be provided. While formulating this Standard assistance has been drawn from the following International Standards: IEC 62253:2011 Photovoltaic Pumping Systems Design qualification and performance measurements IEC :2016 Photovoltaic (PV) module safety qualification Part 1 Requirements for construction 1

5 IEC :2016 Photovoltaic (PV) module safety qualification Part 2 Requirements for testing IEC :2007 Environmental testing Part 2-6: Tests Test Fc: Vibration (sinusoidal) IEC :2005 Environmental testing Part 2-30: Tests Test Db: Damp heat, cyclic ( h cycle) For the purpose of deciding whether a particular requirement of this standard is complied with, the final value, observed or calculated, expressing the result of a test, shall be rounded off in accordance with IS 2 : 1960 'Rules for rounding off numerical values (revised)'. The number of significant places retained in the rounded off value should be the same as that of the specified value in this standard. 2
