The Solar Lighting Laboratory of The Energy and Resources Institute (TERI) in New Delhi, India is open and ready for business.  Last year, SERC director Arne Jacobson and I traveled to New Delhi to complete a hands-on training for the Solar Lighting Laboratory and have since evaluated the laboratory’s work testing off-grid lighting products. Through SERC’s support and the Solar Lighting Laboratory’s hard work, TERI has established the first Asian laboratory within the Lighting Global Quality Assurance Program test laboratory network.

TERI’s Solar Lighting Laboratory will be evaluating off-grid lighting products using the International Electrotechnical Commission’s standard TS 62257-9-5. The test methods verify products by checking product ratings; measuring key product parameters such as daily hours of operation, lighting output, and solar power production; and evaluating parameters related to product durability such as LED life, shock resistance, and workmanship of electrical and mechanical parts.

In other news, in response to demand from the off-grid lighting market, the Lighting Global program has decided to extend the existing quality assurance framework to include larger solar home system kits. Compared to the lighting products we currently test, these plug-and-play direct current kits can provide more power for lighting as well as other uses, such as mobile phone charging, radios, fans and even TVs. Over the next two years, SERC will partner with the Fraunhofer Institute for Solar Energy Systems to adapt existing test methods and standards to reliably assess and report the quality of these larger systems.

While expanding our scope, we are also working with our wide range of stakeholders to refine our current test procedures and ensure a reliable and rigorous quality assurance framework that can be sustained for years into the future. As part of this process, Arne and other team members presented to stakeholders at the Global Off-Grid Lighting Association quality assurance symposium in Cologne, Germany in April.

We also remain committed to better promoting and communicating information about the products that have met our Quality Standards in the off-grid lighting market. As part of this ongoing effort, we have re-designed the Lighting Global website to enable interested parties to more easily view and compare 48 solar lighting products produced by over 20 different manufacturers that have met the Lighting Global Minimum Quality Standards.
