Fuyao said the product embeds solar cells within laminated automotive glass, allowing sunlight to be converted into electricity for auxiliary vehicle loads. The company describes the technology as a “solar sunroof,” rather than a photovoltaic system covering the entire vehicle roof. According to Fuyao’s official product information, the electricity can be used to power onboard electrical equipment.

Several Chinese automotive media reports since February have claimed that the system was jointly developed with BYD and would be offered on the Han and Tang models for an optional price of CNY 8,000 ($1,190). Other widely circulated figures include a peak output of 720 W and a conversion efficiency of 23.18%, based on heterojunction (HJT) solar cell technology.
However, neither Fuyao nor BYD has published technical specifications or a joint announcement confirming those figures. During a March investor briefing, Fuyao declined to identify its customers or disclose pricing, saying both were commercially confidential.
Fuyao recently said its factories in Fuqing Yangxia and Hefei had each reached production capacity of 3 million sets of automotive glass by the end of 2025 and were ramping up production in 2026. It has not disclosed what proportion, if any, of that capacity is dedicated to solar sunroofs.
