BioSolar Nears UL Certification For BioBacksheet


BioSolar Inc., developer of a technology to produce bio-based materials from renewable plant sources, says that production samples of its innovative BioBacksheet product have successfully completed all critical Underwriter's Laboratories (UL) initial material property tests. The product is expected to officially obtain full UL material certification soon.

The initial material property UL certification tests included material identification, partial discharge, fire resistance and other tests that are required before BioBacksheet can be used commercially in solar panels.

The last remaining test for BioBacksheet is the measurement of relative thermal index (RTI), which is the temperature below which material will retain its desired electrical and mechanical properties and not be compromised via thermally induced chemical degradation. A provisional RTI value will be assigned to BioBacksheet approximately 90 days into the RTI testing, the company says. After that, commercial solar panels using BioBacksheet can be submitted for final panel certification or recertification under UL 1703 prior to sale in the general marketplace.
