Globally unique, our testing is ISO 17025 certified


The Photovoltaic testing facility at National insti-tute of solar energy is an independent test laboratory and engaged in testing of solar PV module, systems BOS and components as per national and interna-tional standards. In order to accomplish these activi-ties PVTF is having 3 different laboratories i.e. PV module testing lab, advanced SPV systems & light-ing lab and battery test lab. The etailed activities being taken up at these laboratories are as below:

PV module test lab:

The PV module test lab is a NABL (National accreditation board for testing & calibration laboratories) accredited laboratory in accordance with the standard IS/IEC 17025: 2005 for qualification testing of PV module as per IEC 61215:2005/ IS 14286:2010 with the range of testing up to 600W. The facility for conducting the testing for safety standard i.e. IEC 61730-1, 61730-2 and salt spray test is under accreditation. In addition to this, the laboratory offers wide range of services to the Customers such as Quantitative and Qualitative analysis of PV modules and assessment of the degradation mechanism by way of conducting the EL test.

Performance measurement

The performance of PV modules is measured under stand-ard i.e 25°C module temperature, AM 1.5 spectrum and 100mW/m2 intensity and different test conditions in accordance with IEC standard 60904-3.


Qualification testing of PV modules as per IEC standards.

Performance measurement The performance of PV modules is measured under stand -ard i.e 25°C module temperature, AM 1.5 spectrum and 100mW/m 2intensity and different test conditions in accordance with IEC standard 60904-3.Qualification testing is designed to accelerate and induce many of the same failure mechanisms that the module will be subjected to in the field. Procedures involve a set of well-defined accelerated stress tests irradiation, environmental, mechanical and electrical tests - with strict pass/fail criteria based on functional- ity/performance, safety/insulation and visual require - ments according to relevant standards.

Benchmark against expected performance parameters through relevant standards through root-cause analysis.Drawing on relevant field experience, these test se-quences will also inspect module characteristics. Aim of this testing is to enable rapid quality control on a spot check basis.This includes the following:

  • Performance benchmarking
  • Performing output characteristics with stress-run

Thermal imaging

Thermal imaging by the use of an infrared thermography camera measures the thermal irradiance of a PV module.

  • To identify defective cells with hotspots.
  • Possible to check the junction boxes for material failure in PV modules.

Multiple repetitions of benchmarking is possible.Benchmark test pattern can be used by manufactur-ers, product developers, EPCs, traders and operators who wish to have their products tested independent-ly. Individual benchmark tests (e.g. IEC +100%) allow increased security for manufacturers and investors.

Potential Induced Degradation (PID)

PID is a failure mechanism, which is currently much discussed.In a PID test the module’s sensitivity towards electrical potential differences between cell and frame / glass is tested. We test and evaluate the module’s sensi-tivity according totechnical guideline as per IEC 62804


The Electroluminescence enables detailed quality check of all types of PV modules, phenomenon to im-age micro-cracks, cell failures and inhomogenities
