The Sihong 100MW PV project, a solar-fishery plant constructed by SPIC Jiangsu Electric Power Co., Ltd. has taken the lead in grid-tied power generation. The project fully uses the most advanced Huawei FusionSolar 1500V Smart PV Solution.
The Sihong Hybrid Fishery-Solar 100MW PV project is located in Suqian city, Jiangsu province, covering an area of about 2km2. The large-scale PV power plant was built on the local lake, intertidal zones and fish ponds. Multipurpose use of land increases both the agriculture and fishery revenue, and improves the integrated utilization efficiency of land.
Advanced N-type Bifacial PV Modules are used and a total of 51 transformer stations are installed.
The rear radiation of the bifacial PV module is uneven. As a result, the overall output power of the PV module is different, and the current discrete rate of the PV module reaches more than 5%. In this case, the MPPT granularity of inverters should be finer.
The project fully adopts Huawei 1500V Smart PV Solution with 1000 inverters in total. (Note: The 1500V string inverter in China is SUN2000-100KTL, while in India is SUN2000-95KTL-INH0.) Every two strings connected to Huawei SUN2000-100KTL inverter dedicated for bifacial PV modules from one MPPT circuit, which means that the inverter has the finest MPPT granularity in the industry. This minimizes the mismatch caused by bifacial PV modules.
After the project is completed, it is estimated that the annual energy yield will be 143.67 million kWh, promoting the comprehensive development of ecological fishery and the construction of an advanced state-level PV power generation application base.
The 1500V PV system becomes the global trend and is the preferred solution to reduce costs. The 1500V smart PV system with bifacial PV modules reduces the LCOE (levelised cost of energy) helping customers to achieve grid-tied power generation at a fair price.
SPIC is one of China’s top five power generators, and an integrated energy group with power as its core. SPIC has the greatest total installed capacity of solar power in the world and owns a complete industry chain in PV power including R&D, planning and design, manufacturing of polysilicon, cells and modules, project construction, training, etc.
