Everyone is familiar with solar water heaters. Have you heard of the solar roof? It is not the myth of Bill Gates' high-tech residence. The reporter learned yesterday that with the solar glass production line put into operation, the solar roof will approach the public.
Absorbing solar energy is like a sunflower
At a factory in Xishan Bridge, Yuhuatai, solar glass can already be produced. The emphasis on embossing design, the plant's technical director told reporters that this is the new development trend of solar glass, if it is ordinary flat solar glass, and once the embossed design, there will be a small pit on the surface of the solar glass. This will absorb more solar energy.
Of course, the power supplied to solar cells will also be stronger through solar glass. Because of this, the integrated glass curtain wall of photovoltaic building has become the development trend of the combination of construction industry and solar energy utilization in the world today, and has also brought new business opportunities to the development, application and market of solar glass.
The current mainstream product is ultra-white tempered embossed glass with a thickness of 3.2 mm. The transmittance of the solar cell in the spectral response range is over 91%. According to the law of sunshine in the area, many solar panels placed on the roof are facing southwest.
Solar power meets public lighting
So how does the solar power generated change life? The reporter learned that there is already a high-tech solar power station in China.
That is the 1 MW grid-connected solar photovoltaic power station located in Shenzhen Garden Expo Park. As the largest grid-connected photovoltaic power station in Asia, the total capacity of the power station is 1000.322 kW, and the annual power generation capacity is about 1 million kWh. The long life of the Solar Panel can reach more than 60 years, and the demolition and movement is more convenient.
According to the introduction of Shenghan Glass Consulting (Shanghai) Co., Ltd., Shanghai has already installed pilot solar panels in the community. The public lighting of the pilot community is now self-sufficient.
The electricity generated by the photovoltaic roof can also be sold.
Photovoltaic roofs that use solar power do not only stay in the lab. Currently, the urban photovoltaic roof plan has been launched. According to the introduction of the power sector, photovoltaic roof projects are being implemented in Shanghai, Beijing, Guangdong, Jiangsu, Shandong and other places, with a focus on big cities.
According to the information disclosed by the Energy Conservation Office, the province will launch a photovoltaic roofing plan, which will arrange a photovoltaic glass on the roof and connect it to the grid to use the solar energy to let the house generate electricity by itself.
In Jiangsu, the first photovoltaic roof plan, a photovoltaic glass is placed on the roof, connected to the grid, and solar energy can be used to make the house generate electricity by itself.
In Jiangsu, the first photovoltaic roof plan is located in Wuxi National Industrial Design Park. The power station has been built and the power grid has been laid. Wuxi Suntech and the provincial power company have also signed a grid connection agreement. The electricity generated by solar energy will be acquired by the provincial power company.
According to the development plan of renewable energy in Jiangsu Province, by 2010, 10,000 photovoltaic roof plans will be completed, and photovoltaic grid-connected power generation capacity will reach 50,000 kilowatts. In the use of solar power, in addition to the full acquisition of power grid companies, it will learn from foreign practices, encourage corporate acquisitions, and residents to subscribe.
