There are many problems in the power consumption of Industrial Park, such as large power consumption, high electricity fee and the influence of power rationing. With the continuous emergence of PV innovative technologies and products and the gradual implementation of the new national PV policy, many factory owners began to pay attention to and use solar power. At the end of December last year, the PV power station on the roof of the No.1 Workshop of Talmao medical products (Hangzhou) Co., Ltd. located in Xiasha Economic Development Zone of Hangzhou was successfully built and connected to the grid. The innovative method of installing the flat PV board on the concrete roof of the project is worthy of attention!

Generally, the PV power station built on the concrete roof adopts the crystalline silicon PV board, and sets a certain angle of inclination when laying according to the local lighting conditions, so as to improve the power generation capacity of the power generation system. Due to the possible occlusion of the front and back of the PV array with inclination angle, a certain channel will be set between the array rows, which reduces the utilization rate of the roof area to a certain extent.

On the roof of Talmau's workshop, you can see rows of pure black PV boards are laid neatly and intensively. Why does this project not use the best angle of inclination? What's the new black product?

Gang Bao, the investor and builder of the project and the sales director of ASP, has opened the answer for us. He said that the roof PV power plant project of Talmao company has several particularities. First, the plant is located in Hangzhou Economic and Technological Development Zone, which is located at the tuyere. Therefore, the owner hopes that the project will be affected by the typhoon as little as possible, with good safety. Second, the plant is located in the center of the economic development zone, surrounded by high-end hotels, large-scale commercial buildings, large hospitals, office buildings, etc , high environmental requirements. Therefore, according to the requirements of the owner, ASP decided to give up the traditional inclined laying method after research, but give full play to the advantages of the company's patented product - high efficiency CdTe thin film PV module, and make a flat concrete roof PV power station.

The tiling method benefits from the unique characteristics of ASP's products. First of all, the sensitivity of CdTe PV module to the change of light incidence angle is low, and the power generation efficiency is little affected by the change of inclination angle. Therefore, it can still have strong power generation capacity under the condition of tiling. Because of the high utilization rate of the tiling area, the power generation capacity of the project is stronger as a whole; second, the color of CdTe PV panel is pure black, and after the tiling, the light will be reduced through the antireflection treatment The reflected light on the v-plate will not have a direct impact on the surrounding buildings, effectively avoiding light pollution. Not only that, as the governing unit of Hangzhou PV Association, ASP specially invited Hemai Power Electronics Technology Co., Ltd., the supervisory unit of the association, to provide series inverters for the project, so as to further improve the power generation efficiency of the system.

The installed capacity of the PV power station on the roof is 300kW, and the annual power generation is about 300000 degrees. The project adopts the contract energy management project mode. Telmao not only does not pay a cent, but also enjoys the preferential electricity price of 300000 degrees per year. Gang Bao said: "Telmao provides roof mounted PV power station for free, and ASP contributes to the design, construction and maintenance of PV power station. For the green and environmental protection power generated by the PV power station, ASP provides it to Telmao at a more favorable price than the grid, as the compensation for the roof provided by Telmao. In this mode of cooperation, ASP can recover its investment in about five years by selling PV power generation and government subsidies. In addition to saving 30000 yuan of electricity fee every year, Talmao can reduce carbon dioxide emissions by about 300 tons every year, with obvious environmental benefits and improved the environmental image of the enterprise. "

The industrial park has become the main force of large-scale promotion of PV applications. More and more parks begin to invite professional PV power plant investment and construction enterprises to install PV power plants on the roofs of their original idle plants.
