Mitsui Chemicals’ solar lab becomes NABL accredited to test high-efficiency modules


Japan-based Mitsui Chemicals has announced that its solar PV Lab in India has received NABL accreditation to test high-efficiency PV modules, including PERC and bifacial modules

The lab—based in Ahmedabad—offers a wide spectrum of services for ensuring quality from factory to field in partnership with technical advisor PI Berlin based in Germany. 

“It is furnished with state-of-the-art equipment which are technologically advanced to perform testing of all commercially available module technologies in the current solar PV market,” as per the company.

The lab has chosen Eternalsun Spire’s Xenon based high-accuracy, single-long-pulse flasher for testing of high-efficiency modules including bifacial and PERC technology. 

The A+A+A+ class illumination of the system during the wide spectrum range from 300 to 1200nm (with >99% spectral coverage) ensures accurate measurements according to IEC 60904-9 Ed3 standard. 

Also, Eternalsun Spire’s steady-state, large-area sun simulator performs stabilization, light-induced degradation (LID) and hot spot endurance test according to IEC 61215 and temperature test according to IEC 61730.

Puneet Kumar Maurya, Lab manager of Mitsui Chemicals – Solar PV Lab, said: ”As a part of a Japanese conglomerate, we always give emphasis to ensure quality and become a trustworthy partner to customers. We are glad to add the Xenon-based single-long-pulse flasher and steady-state solar simulator from Eternalsun Spire to our PV lab. As we have the vision to emerge as one of the best consulting and testing services provider, it enables us to test all current and future PV modules with the highest measurement precision.”

Pepijn Veling, Sales director of Eternalsun Spire, added: “Our goal is to contribute to the trust in the solar industry In India by enabling global labs such as Mitsui to offer the highest degree of measurement control and certainty to PV module buyers and manufacturers in India.”

Eternalsun Spire is a Netherlands-based leading manufacturer of solar simulators and integrated climate chambers for measuring the performance and reliability of PV modules. It serves a global customer base of PV module manufacturers, research institutes and test laboratories.
