Distributed PV Building Demonstration in Jiangsu

On August 5th, a row of photovoltaic power generation panels was installed at the Jiangsu Electric Power Research Institute's parking lot in Jiangning District of Nanjing City to take up part of the unit's power supply tasks. This marks the first successful demonstration of a distributed building photovoltaic demonstration application system project containing multiple types of PV modules in Jiangsu Province.

Jiangsu Academy of Electric Power in order to further study the problems faced by photovoltaic building integration, in November last year to build a photovoltaic demonstration application system, focusing on building photovoltaic types and adaptability, visual integration technology of photovoltaic and building bodies, power generation efficiency optimization technology and other research A detailed construction plan was formulated to ensure the high quality of the project.

With the steel structure of the parking lot as the carrier, the Jiangsu Academy of Electric Power conducts the construction of a distributed building photovoltaic demonstration application system on the shed. Three types of photovoltaic modules, polycrystalline, monocrystalline and thin-film, are installed on the shed, with a total installation area of ​​850 square meters and a total installed capacity of 105 kilowatts. The system accesses the distribution network of the park with a voltage level of 0.38 kilovolts. The designed annual power generation capacity is about 110,000 kilowatt-hours, which is equivalent to saving 39.42 tons of standard coal and reducing emission of 109.17 tons of carbon dioxide.

Based on the operation of the system, the Jiangsu Academy of Electric Power will conduct follow-up studies and comparative analysis on the operating characteristics and power quality of different types of photovoltaic modules, and summarize the problems and applicable conditions for the generation of different types of modules for photovoltaic power generation system planning and construction. Installation access, monitoring and protection are provided for reference, providing technical support for distributed photovoltaics in large-scale deployment and application in Jiangsu. It is reported that distributed building photovoltaic is an important part of the distributed photovoltaic application research of Jiangsu Academy of Electric Power. In the future, demonstration projects such as single-axis tracking and multi-axis tracking photovoltaic power generation systems and low wind speed wind power generation systems will start one after another.
