ET Solar Group has revealed that its multi-crystalline ET-P660240 module has shown high yield performance in the outdoor tests conducted by Photon Laboratory.

Launched in 2010, the modules have a maximum unit power output of 240 watts. Sold mainly in Europe, the modules account for a large proportion of ET Solar’s total sales. 

In a recent test conducted by Photon Laboratory, the ET-P660240 module achieved 629kWh/kW in yield performance during the 8-month test. It ranked highest in all multi-crystalline modules against various module producers that the laboratory tested outdoor under the same conditions.

Dennis She, President and Chief Executive Officer of ET Solar, commented, “We are delighted that our modules performed very well in this rigorous test. This is one very good example of how our strong efforts to ensure world-class product quality paid off. We are confident to achieve top results in the yield performance test eventually and look forward to working with Photon Lab and other international testing organizations closely on product quality and performance validation going forward.”

Photon Laboratory is a globally recognized PV system testing and measurement facility. Since 2005, it has been measuring energy yield of solar modules from world's leading PV module manufacturers. The measurement tests compare the energy output, on a per kilowatt basis, of participating modules.
