PVTIME – The Greater Bay Area’s first integrated perovskite PV-storage-charging demonstration project has successfully connected to the grid and begun operating officially in Shenzhen’s Pingshan District. Jidian Optoelectronics and Shenzhen Xianxiang PV Technology collaborated to supply the project’s perovskite modules and vertical PV components, promoting the practical use of advanced PV technologies.
Spanning approximately 4,000 square metres, the initial rooftop distributed PV system has a total capacity of 76.68 kWp. This includes 45 kWp of high-efficiency monocrystalline TOPCon modules and 31.68 kWp of UtmoLight’ state-of-the-art 0.72 m² perovskite modules. The project now serves as a new renewable energy benchmark, integrating the validation of cutting-edge technology, the use of new materials, smart energy management, and deep industry collaboration.
On 10 June 2025, a day with strong sunlight, operational data showed that the monocrystalline TOPCon system reached a maximum power output of 44.011 kW, equivalent to 97.80% of its rated capacity. The perovskite system delivered an impressive performance, exceeding expectations by hitting 33.001 kW and surpassing its rated capacity by 4.17%, generating 6.37% more power per kW than the monocrystalline modules. It also maintained 100% system efficiency throughout long-term operation, challenging conventional assumptions about PV module performance. These figures provide valuable data for the design and operation of future perovskite projects across the Greater Bay Area and the wider country, highlighting the advantages of perovskite in terms of operational power and system efficiency.
While monocrystalline TOPCon modules already outperform monocrystalline PERC modules in terms of low-light response and temperature coefficient, perovskite modules demonstrated higher power generation per installed kW and longer equivalent operating hours under the same conditions. Between 10 and 30 June, their equivalent operating hours were 6–14% higher than those of the TOPCon modules, further confirming their strong low-light performance and potential for use in challenging climatic conditions.
