BART STATION · UNION CITY, CALIFORNIA, UNITED STATES
RENOVATION
The refurbishment of Union City’s high-speed multimodal station near San Francisco included a drop-off canopy incorporating Onyx Solar’s crystalline silicon photovoltaic glass. This canopy structure utilized nearly 800 pieces of laminated safety glass, each consisting of 5/16” over 5/16” fully tempered glass. The photovoltaic glass panels, sized at 1,805 mm x 1,137 mm (5.92 x 3.73 Ft), generating 175,000 kWh/year. To enhance the interior aesthetics, the glass features a white color ceramic frit on surface that partially conceals the solar cell screen print on its reverse side.
The photovoltaic glass at Union City BART station, which can reach a nominal power of 140 Wp per square meter, with a VLT of 25% and a g-value of 20%, perfectly aligns with the project's sustainability and architectural goals. It enhances energy efficiency by allowing natural light to filter through, reducing the need for artificial lighting while providing shade. The combination of safety, energy production, and design aesthetics makes this installation an ideal solution for a high-traffic public transportation hub, ensuring a harmonious blend of technology and urban functionality. This innovative use of photovoltaic glass panels meets the needs of both the station’s users and its environmental objectives.
