In recent years, the photovoltaic industry welcomes a new spring in the mainland. Upon this trend, Radiant also focuses on the construction of photovoltaic power plant. In this year, Xu Jianrong, General Manager of Radiant, leaded the technical team to make a long-term planning and survey on this Project. According to the planning, photovoltaic modules (installed capacity of 250KWp) will be installed on the rooftop of the new workshop, including rooftop photovoltaic power generation system and relevant mating grid connection facilities. This Project will be completed in the end of November, 2014.

Design of photovoltaic power generation system

　　Photovoltaic modules are installed on the top of roofs of different workshops. Rooftop photovoltaic set is provided with 5 sets of 50kW inverters. After 380v AC, photovoltaic inverter is directly connected to busbar at 400V output side of 10VkV/0.4kV transformer. This Project is a 380V user-side network connection system. Power is generated and used by this Project. Surplus electricity will be connected to the grid.

Simulation of photovoltaic power generation capacity 

　　The installed power of this Project is 250KW. Combining sunshine duration and solar energy radiant quantity of local solar energy, the simulated photovoltaic power generation capacity is listed as follows:

　　Daily capacity of the photovoltaic power plant: approximately 817kWh;

　　Annual capacity of the photovoltaic power plant: approximately 298,205kWh;

　　25-year capacity of the photovoltaic power plant: approximately 6.7096 million kWh;

Yearly average standard coal saved	104669.955kg
Yearly average emission reduction of CO2	295222.95kg
Yearly average emission reduction of SO2	2415.4605kg
Yearly average emission reduction of NOX	1180.8918kg
Yearly average emission reduction of dust	603.865125kg

　　At present, distributed photovoltaic power generation is encourage in national policies. Distributed photovoltaic power generation makes the utmost of the wide existence feature of solar energy. Moreover, it avoids limiting factors of sites constructed in a concentrated way. Distributed photovoltaic power generation is characterized with flexible construction. Photovoltaic power generation can be said as inherent distributed energy resource. After the application of photovoltaic power generation system in this Project, Radiant will continue to devote itself to development and utilization of new energy and adhere to the enterprise declaration of “Change our life with solar energy, restore the world with green energy”.
