Disclosure to Promote the Right To Information Whereas the Parliament of India has set out to provide a practical regime of right to information for citizens to secure access to information under the control of public authorities, in order to promote transparency and accountability in the working of every public authority, and whereas the attached publication of the Bureau of Indian Standards is of particular interest to the public, particularly disadvantaged communities and those engaged in the pursuit of education and knowledge, the attached public safety standard is made available to promote the timely dissemination of this information in an accurate manner to the public.
Certain oonverrllons ere, howevei. Measurement principles for terrestrial photovoltaic PV solar devices with reference spectral jrradiance data lEC QG 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 Data from on-site array measurements contain diode, cable and mismatch losses.
Therefore, they are not directly comparable to the sum of the respective module data. 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. At the lime of publication, the editions indicated were valid.
All normative documents are subject to revision, and parties to agreements based on this International Standard are encouraged to investigate the possibility of applying the most recent editions of the ice documents indicated below.

The choice of these selected modules will be based on the principles and examples indicated 618229 l. Report the point ot connection. It slaw manual load scanning is used e. It not, repeat 5. 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 re ere iev device at the start of the scan. In cases of special mountings, i.
If necessary, regression analysis can be used to improve the accuracy of the other coefficients. If slow manual load scanning is used e. If not, the measurement should be repeated from 5.
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. The Rq value will either be given by the supplier or determined by measurement as in lEC Reference values of 6829 temperature, in-plane irradiance and spectral distribution, specified for power rating of PV arrays.
Standard test conditions STC: Reference values of module temperature, in-plane irradiance and spectral distribution used for 61289 simulator measurements: AM 1 ,5 global- see lEC A reference device is a specially calibrated solar cell, multi-cell paclcage or module wliicti is used to measure irradiance.
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.
International Standard Title lEC Requirements for reference solar modules Only 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 the purpose of deciding whether a particular 6189 of this standard is complied 618829, the final value, observed or calculated, expressing the result of a test, shall be ice off in accordance with IS 2: The number ie significant places retained in the rounded off value should be same as that of the specified value in this standard.
