UL Launches First Mobile PV Test Laboratory In India

Mobile facility helps solar plant owners maximize energy while minimizing downtime and shipping risks

UL, a global safety science company, today announced the launch of its first Mobile PV Testing Laboratory in New Delhi, India. The mobile testing laboratory capabilities offer solar PV system owners and operators the ability to identify, evaluate and replace underperforming modules directly at the solar plant site, allowing them to minimize downtime while maximizing their energy production. UL is the first independent third-party certified and accredited company to launch a mobile PV testing laboratory in India.

The mobile facility combines an A + A + A solar simulator with a high-resolution electroluminescence test system according to IEC 60904-9. It enables standard-compliant and precise on-site testing at maximum throughput. In one shift, a detailed check can be performed for up to 300 modules. The unit can conduct tests on insulation, performance with low irradiance, performance at Normal Operating Cell Temperature (NOCT) and temperature coefficient.

The mobile facility helps detect under performance as well as hidden defects such as micro cracks, inactive areas or hotspots in the module quickly and reliably. UL, with its decades of experience in solar testing, has developed an innovative process through which the test results of the mobile facility are close to laboratory testing output. This will allow developers and manufacturers to address quality gaps and ensure the right product reaches the market.
