In the past decade, NCPRE along with National Institute of Solar Energy (NISE) has conducted 4 pan India surveys to monitor reliability and durability of PV modules. Modules in different climatic zones across the length and width of the nation were monitored. Various tests such as measurement of I-V characteristics under light, infra-red (IR) thermography under light, electroluminescence (EL) imaging, interconnect integrity test, measurement of irradiance, etc are conducted in these surveys Based on the data, the reports (available on NCPRE website) propose various recommendations for the photovoltaic community. These recommendtions, if adopted with seriousness, will ensure that the installations coming up in future will show better overall performance than we have seen so far, and thereby ensure the success of the National Solar Mission.
