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 61730-1:2016 – Photovoltaic (PV) module safety qualification – Part 1 –

Requirements for construction


2

IEC 61730-2:2016 – Photovoltaic (PV) module safety qualification – Part 2 –

Requirements for testing

IEC 60068-2-6:2007 – Environmental testing – Part 2-6: Tests – Test Fc: Vibration

(sinusoidal)

IEC 60068-2-30:2005 – Environmental testing – Part 2-30: Tests – Test Db: Damp

heat, cyclic (12 + 12h 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.

1 SCOPE This Standard specifies the technical requirements for Solar Photo Voltaic Water Pumping Systems for handling clear cold water covering design qualifications and performance

specifications. These pump sets can be installed on a suitable bore-well, open well, water reservoir, water stream, etc. 2 REFERENCES The Indian Standards listed at Annex A contain provisions which, through reference in this text, constitute provision of this standard. At the time of publication, the editions indicated

were valid. All standards are subject to revision, and parties to agreements based on this

standard are encouraged to investigate the possibility of applying the most recent editions of

the standards. 3 TERMINOLOGY In addition to the terminology specified in Clause 3 of IS 5120 and IEC 62253, the following

shall also apply. 3.1 Static Water Depth — It is the depth of water level below the ground level when the pump is not in operation. 3.2 Draw-Down — It is the elevation difference between the depth of static water level and the consistent standing water level in tube well during operation of pump set. 3.3 Submergence — It is the minimum height of water level after drawdown above the pump suction casing. 3.4 Manometric Suction Lift — Manometric suction lift is the vacuum gauge/suction manometer reading in meter of water column when pump operates at suction lift. 3.5 Daily Water Output — It is the total water output on a clear sunny day with three times

tracking Solar Photo Voltaic (PV) panel, under the “Average Daily Solar Radiation” condition of 6.5 KWh / m

2 on the surface of Photo Voltaic (PV) array (i.e. coplanar with the

Photo Voltaic (PV) Modules). 3.6 Wire to Water Efficiency — It is the combined efficiency of Solar Photo Voltaic (PV)

Converter/Controller with Inbuilt MPPT mechanism, Pump set and piping. 3.7 Clear Cold Water — Clear cold water shall mean, water having the characteristics specified below:

have to be agreed between the manufacturer / supplier & user and shall be specified in the

order.

3.8 Solar Photo Voltaic (PV) Converter

The PV Converter converts the DC voltage of the PV generator into a high or low DC voltage

or converts this DC voltage and/or DC current into one-phase or multi-phase into alternating-

current voltage or alternating current. Note:

1. The PV converter may also include equipment for MPPT, monitoring, metering and for

protection purposes. 3.9 Maximum Power Point Tracker (MPPT) MPPT is an algorithm that includes charge controllers used for

extracting maximum available power from Photo Voltaic (PV) module under certain

conditions. The voltage at which Photo Voltaic (PV) module can produce maximum power is

called 'maximum power point' (or peak power voltage).
