At present, the largest thin-film battery solar photovoltaic curtain wall has been built in China.

the amorphous-microcrystalline double-junction thin-film solar photovoltaic curtain wall of workshop c of Zhejiang zhengtai solar technology co., ltd., with an installation area of 2,511 square meters, has been successfully connected to the grid for power generation recently. This national golden sun demonstration project, which was successfully declared last year, has been tackled day and night by Chint international solar experts and scientific and technical personnel, and has been closely coordinated by Chint solar system division, film production department, quality department and external processing unit, and has successfully completed the curtain wall design, component production, external processing and transportation installation and debugging.

compared with the crystalline silicon photoelectric curtain wall, the thin film photoelectric curtain wall has lower cost and can absorb energy to generate electricity in weak light. Zhejiang Zhengtai Solar's 511KW photovoltaic building project, which consists of multiple battery arrays, will be completed by the end of this year, with an estimated annual power generation of 558,811 kW/h..
