UL7103 is the national safety standard for Building-Integrated Photovoltaics (BIPV). BIPV is a solar power technology that incorporates solar-generating materials into building components, such as roofs. The UL Certification indicates a product or service meets local and federal environmental and safety regulations. This signals to consumers that the manufacturer follows standards for quality and safety. Timberline Solarâ„¢ was the first product in the world to be certified to this standard.
