The project adopts 222 pieces 260 polysilicon solar modules, 2 sets of INVT BG30KTR inverter. Project adopts the stent tiling model, the total installed capacity is 57.72KWp, 380v low voltage grid-connection. The annual power generation is expected to be 45,800 degrees.
The project adopts the cooperation mode of contract energy management, building owners provide roof for free and solar power generation is sold to buildings owners at current electricity prices by 80% discount.

4.8 m building parapet height is the project difficulty, we need to build 4.3m and 0.3m cement foundation to ensure that the solar module is not covered by the parapet.
The project achieves grid-connection in January 2017 and is in normal operation at present.
