  • 1. What Does The Photovoltaic Industry Do?

    Photovoltaic power generation is a technology that utilizes the photovoltaic effect of semiconductor interfaces to directly convert light energy into electrical energy. The key component of this technology is solar cells. After being connected in series and packaged for protection, solar cells can form a large area of solar cell components, which, in combination with power controllers and other components, form a photovoltaic power generation device. The advantage of photovoltaic power generation is that it is less limited by geographical conditions, since there will always be sunlight on earth. The photovoltaic systems also have the advantages of safety and reliability, noise free, low pollution, no need to consume fuel, on-site power generation and supply without the installation of transmission lines, and short construction cycles.

  • 2. China's Photovoltaic Industry.

    1. Photovoltaic + Industrial and Commercial Factory Roofs

    From a commercial perspective, large enterprise factories, supermarket chains, and private enterprises all have advantageous rooftop resources. Most of these enterprises are large consumers of electricity, and the rational utilization of rooftop energy would be a potential huge wealth.

    The industrial and commercial roofs have a large area, flat roofs, high electricity consumption, and high electricity prices, resulting in a large installed capacity and large power generation. From an investment perspective, industrial and commercial power plants are a better investment. Installing photovoltaic power plants on the roof of industrial and commercial buildings can effectively activate fixed assets, save peak electricity costs, and obtain good electricity revenue. At the same time, it can reduce the internal temperature of the factory and promote energy conservation and emission reduction.

    2. Photovoltaic+ Car Shed/Parking Lot

    Photovoltaic shed is the most simple and feasible way to combine with buildings. Photovoltaic shed, corridor and other facilities, together with charging station and other facilities, can not only improve the comprehensive utilization rate of urban space, but also maximize the convenience of citizens' travel. Photovoltaic shed has good sun and rain protection and heat absorption, and can also realize the integration of light (storage) and charge, providing clean energy for new energy vehicles and electric cars. It is more and more used in industrial parks, commercial areas, hospitals, schools, etc.

    3. Photovoltaic + Logistics/Warehousing Center

    Through the organic integration of industrial park construction, new energy development, and the Internet, the logistics center aims to create a public and open service platform that integrates the three major sectors of new energy, logistics, and e-commerce, achieving the cultivation and incubation of logistics enterprises, new energy enterprises, e-commerce enterprises, and commercial enterprises, which forms a unique green business ecosystem.

    4. Photovoltaic + Communication Base Station

    Nowadays, China has a large number of communication base stations, which are widely distributed and must be powered 24 hours a day. In the absence of access to distributed photovoltaic power, in case of power failure, the staff need to start the diesel generator to ensure temporary power supply. The operation and maintenance cost is high. If the distributed photovoltaic power generation system is added, it has high installation value in terms of practicality and economy.

  • 3. A Case Study of The Photovoltaic Industry?

    1. Solar Village, Freiburg im Breisgau, Germany

    Freiburg im Breisgau Solar Village is the first community in Germany to use solar technology to supply power. Its solar power generation project has been built since 1996, with a total of more than 2700 square meters of solar panels. The project aims to combine solar photovoltaic technology with the concept of sustainable development, achieving multiple benefits in various pespectives of energy, environment, society, and economy.

    2. Ivanpah Solar power station, Nevada, USA

    Ivanpah solar power station is the largest solar thermal power generation project in the world, with a total scale of 392 MW. This project utilizes a large area of parallel mirrors (i.e. solar reflectors) to reflect sunlight onto the central collector, focusing the sunlight on the pipes on the collector. Steam is generated through the working medium in the pipes, driving the turbine to generate electricity. This project fully utilizes the abundant sunshine time in Nevada to provide clean energy and create employment for the local area.
