BioSolar has advised that the production samples of its BioBacksheet technology have finished most of the Underwriter’s Laboratories (UL) material property tests and is on its way to receiving full UL certification. Tests on the product have included: material identification, partial discharge test and resistance to catching fire among other UL led testing. The last test, a measurement of relative thermal index (RTI) will soon be conducted.

Dr. David Lee, BioSolar’s CEO, commented, “We are excited to receive positive test results on all of our material properties from UL. We are now in the final stretch before our ‘green’ and lower cost BioBacksheet can be commercially made available to solar panel manufacturers. Based on our internal tests, we do not anticipate any problems in achieving an RTI rating that exceeds the requirements of solar manufacturers.”
