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.

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.

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.

1. Clean and environmentally friendly: Photovoltaic power generation does not generate pollutants and greenhouse gases, and does not pose any harm to the environment.

2. Renewability: Solar energy is a renewable energy source that is more sustainable and long-term compared to fossil fuel energy.

3. Distributed generation: distributed photovoltaic power generation can convert the power consumption site to the power generation site, reduce transmission loss and increase power supply reliability.

4. Abundant resources: Solar energy is a widely existing renewable resource, which can be obtained almost everywhere in the world without geographical restrictions.

5. Economy: With the progress of technology, the cost of electricity by source of photovoltaic has been continuously reduced, and its cost of electricity by source has become increasingly close to or lower than that of traditional energy.

6. Policy Support: Many countries and regions have introduced policies to support the development of the photovoltaic power generation industry, such as subsidies, tax reductions, and other supporting measures.

In summary, the advantages of the photovoltaic industry lie not only in its environmental friendliness and sustainability, but also in its economic and policy support.

1. Photovoltaic cell module: It is composed of many photovoltaic cell connections and can convert solar energy into DC power.

2. Inverter: Converts direct current into alternating current for ease of use in household appliances, industrial appliances, etc.

3. Support and installation system: Used to install and support photovoltaic cell components, ensuring that the photovoltaic panel can absorb sunlight optimally in the appropriate direction and inclination angle.

4. Cable and junction box: used to connect photovoltaic modules and inverters, transmitting electrical energy.

5. Monitoring system: used to monitor the power generation status, battery panel temperature, current and voltage data of the system, and timely detect abnormal problems.

6. Energy storage system (optional): used to store system power generation, balance the energy difference between load and power supply, and provide emergency power supply in the event of grid failure.

These components form a photovoltaic system, which features technology and operational management to fully utilize solar energy, achieving the goals of energy conservation, consumption reduction, environmental protection, and emission reduction.

1. Silicon material manufacturing process: This process involves the production and refining of silicon materials such as polycrystalline silicon and monocrystalline silicon.

2. Photovoltaic cell manufacturing process: This process involves the manufacturing of converting silicon materials into photovoltaic cells.
