BrightSpot Automation has installed a LoadSpot system for performing mechanical load testing of solar panels at D2solar in San Jose, CA.  

 

The LoadSpot tool is capable of performing the standard IEC61215 mechanical load tests that simulate wind and snow loads on the panels and it does so in an improved manner that leaves the front side of the panels unobstructed, so electroluminescence and IV testing of the panels can be performed as loads are being applied. In this way a single short test can give a clear picture of how cell cracks form as a function of mechanical loading of the module. 

 

Dr. Andrew Gabor, CTO of BrightSpot: “D2solar is a key partner, together with the Florida Solar Energy Center, in our research on understanding crack formation in crystalline silicon solar cells, on the ways to improve solar panel designs to make them less sensitive to crack formation, and on ways to improve tests to reveal the sensitivity of panels to cell cracking. This research, Powered by Sunshot, has already revealed a sensitivity of solar panels to developing cracks at disturbingly low load levels after application of a short, low-temperature exposure.  We have successfully engineered multiple ways to redesign the panels to reduce their sensitivity to cell cracking, and we have developed new testing sequences that address the shortcomings of the IEC testing sequences with respect to this effect.”

 

Dr. Duncan Harwood, CEO of D2solar: “We are excited to be able to offer our clients this unique testing service which helps them optimize their designs, materials and processing with respect to cell cracking and other problems seen during static and cyclic load testing.  We share the same passions as do the staff at BrightSpot regarding the importance of solar panel durability, and we see the LoadSpot as a critical tool to quickly and cost-effectively assess panel quality.”
