If soiled surface conditions exist, appropriate action such as cleaning If praclical andlor reporting the conditions shall be taken. Requirements for refrence solar modules aC Raquirements for reference solar cells lEC Standards are also reviewed periodically; a standard alongwith amendments is reaffirmed when such review indicates that no changes are needed; if the review indicates that changes are needed, it is taken up for revision.
If not, the measurement should be repeated from 5. At the lime of publication, the editions indicated were valid. Therefore, they are not directly comparable to the sum of the respective module data. A reference device is a specially calibrated solar cell, multi-cell paclcage or module wliicti is used to measure irradiance.
Reference values of ambient temperature, in-plane irradiance and spectral distribution, specified for power rating of PV arrays. Standard test conditions STC: For a particular module on-site measurements extrapolated to Standard Test Conditions STC can be directly compared with results previously obtained in laboratory or factory for that module, provided that in both measurements the reference devices have the same spectral and spatial response as described in the relevant I EC If necessary, regression analysis can be used to improve the accuracy of the other coefficients.
If a PV array is formed with sub-arrays of different tilt, orientation, technology or electrical configuration, the procedure described here will be applied to each unique PV sub-array. Users kec Indian Standards should ascertain jec they are in possession of the latest amendments or edition by referring to the latest issue of ‘BIS Catalogue’ and ‘Standards: If a fast load scanning device such as a capacitor load total scan time less than 0,1 s is used, it is sufficient to record the current of the reference device at the start of the scan.
Requirements for reference solar modules Ifc the English language text of the international Standard has been retained while adopting it in this Indian Standard, and as such the page numbers given here are not the same as in the lEC Standard.
For measurements in natural suniigtit, wtien the direct solar beam is not at or near normal incidence, it is recommended to use a reference module of the same type and size as those being tested or a multi-cell pacltage consisting of a calibrated cell surrounded by other ceils dummy or real in such a way that frame, encapsulation system, shape, size and spacing are the same as in the modules being tested. It not, repeat 5. No part of the these publications may be reproduced in any form without the prior permission in writing of BIS.

This does not preclude the free use, in the course of implementing the standard, of necessary details, such as symbols and sizes, type or grade designations. 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: If slow manual load scanning is used e.
