Because these modules can suck up reflected as well as direct sunlight, SANYO is marketing them in combination with Tio-Coat, the DuROCK Alfacing International roofing membrane. Tio-Coat is described as “a high-strength white elastomeric urethane roof coating” that reflects 89 percent of the light that hits it while also insulating the building beneath it, reducing the energy required for the building compared to traditional roof coverings.
Having successfully tested this innovative combination of tech at DuROCK’s international headquarters in Woodbridge, Ontario, the potential for double-sided solar has apparently captured the interest of Avacos Solar (a company also involved in the Woodbridge project) which utilized the two products in conjunction with a building-integrated solar system.
According to Avacos, overall performance of the Toronto project’s 4.6kW solar array was improved due to the cooling effect of Tio-Coat on the roof and the additional reflectivity providing light for the back side of the bifacial modules. The building also features a host of other green features and is a candidate for LEED Platinum certification.
