According to the differences in design, construction, and installation methods, the distributed photovoltaic power station business can be divided into BAPV (Building Applied Photovoltaics) and BIPV (Building Integrated Photovoltaics). Both methods use rooftop to develop distributed photovoltaic power stations to generate photovoltaic power.

Industrial and commercial distributed photovoltaics can be divided into the “all generation to the grid” mode and the “self-consumption first and the excess to the grid” mode according to different consumption modes. The company focuses on the investment and operation of industrial and commercial distributed photovoltaic power stations of the “self-consumption first and the excess to the grid” mode and obtains stable power generation income by selling the power generated by photovoltaic power stations. According to the principle of “self-consumption first and the excess to the grid”, the company signs energy management contracts with the owners of roof resources. After power stations are completed and put into operation, the company will prioritize the owners of rooftop resources based on their electricity needs and give them discounts on the electricity price or pay certain rental fees. If there is still residual electricity after the power generated by the power station is consumed by roof resource owners, the residual electricity will be fully connected to the grid.

• Technical data related to social benefits of photovoltaic power stations

• Installation capacity： 10000m2≈1MWp	Annual power output： 1MWp ≈ 1 million KWH/year
  Annual savings of standard coal ≈360 tons	Annual emission reduction： CO2≈1000 tons，SO2≈30 tons Oxynitrides≈15 tons
  On-grid mode Self-consumption first and surplus to the grid	High voltage power distribution cabinets: High-voltage supply and high-voltage metering (middle-placed switch cabinet, loop grid cabinet) Low metering
  On-grid types High voltage on-grid (10KV, 20KV, 35KV, and 110KV), low voltage on-grid (380V)
