BioSolar Fast-Tracks Plan to Attain Underwriters Laboratory Certification of Bioplastic Backsheet for Solar Cells

Market Wire, October, 2007

BioSolar(TM), Inc. (OTCBB: BSRC), developer of a breakthrough technology to produce bioplastic materials from renewable plant sources that will reduce the cost of solar cells, today announced that the company is moving another step closer to attaining Underwriters Laboratory® (UL®) certification for the company's recently completed bioplastic backsheet material.

"This is a significant step for the company," said Dr. David Lee, BioSolar's CEO, "because certification by Underwriters Laboratories (UL) is required for sales of Photovoltaic modules in the United States, and we have engineered a two-step tactical scenario wherein we can dramatically lessen the amount of time necessary to attain the all important UL Certification."

SBM Solar of Concord, NC, a strategic partner of BioSolar Inc., is in the final process of obtaining UL certification for their all polymer packaged PV module. BioSolar has submitted modules, using its proprietary bioplastic backsheet film, to the National Renewable Laboratory (NREL) for initial testing. Assuming positive results at NREL, SBM will submit additional modules to Underwriters Laboratory for UL approval changing only their standard backsheet material to BioSolar's proprietary bioplastic backsheet film.

"Changing only one item on a UL certified module drastically shortens the approval process. Once this module is certified, the door will be opened for general sales of our bioplastic based backsheet film to the entire PV industry," concluded Dr. Lee.

About SBM Solar

SBM Solar, based in North Carolina, is a photovoltaic (PV) module manufacturer that is dedicated to providing high quality PV modules with patent-pending SBM(TM) technology for a wide range of applications. The current non-glass technology used by SBM's modules will create new opportunities in the PV market and allow the company to expand in the custom-made PV niche market. With the growing range and volume of PV applications, "one type fits all" glass PV modules no longer meet market needs. SBM Solar will be able to offer custom-made PV products with its unique non-glass PV modules.
