Performance comparison of single polycrystalline silicon wafers

Monocrystalline silicon wafers and polycrystalline silicon wafers have significant differences in crystal quality, electrical properties, and mechanical properties. The difference between single crystal and polycrystalline is mainly in the preparation of raw materials. Single crystal is the Czochralski lifting method, polycrystalline is the ingot casting method, and there are only some minor differences in the back-end manufacturing process.

Analysis of common faults of photovoltaic inverters and detailed explanation of treatment methods

Photovoltaic power generation is a technology that directly converts light energy into electrical energy by utilizing the photovoltaic effect of the semiconductor interface. The key element of this technology is the solar cell. After the solar cells are connected in series, they can be packaged and protected to form a large-area solar cell module, and then combined with inverters, power controllers and other components to form a photovoltaic power generation device. The advantage of solar photovoltaic power generation is that it is less restricted by geographical areas, because the sun shines on the earth; the photovoltaic system also has the advantages of safety and reliability, no noise, low pollution, no need to consume fuel and erect transmission lines, and can generate electricity and power locally, and the construction period is short.

Containerized energy storage safety design

Under the national "dual carbon" strategy, new energy sources represented by photovoltaics and wind power are developing vigorously. With the large-scale connection of photovoltaic and wind power, the demand for frequency regulation and peak regulation resources of the power grid has risen sharply, and the energy storage system is in solving new energy consumption. It plays an increasingly important role in increasing the power grid stability, improving the utilization efficiency of the power distribution system, etc. Electrochemical energy storage lithium-ion system, due to its low deployment environment requirements and many applicable scenarios, its application scale is growing rapidly. At the same time of large-scale application, the safety of energy storage power stations has also attracted widespread attention.

Will continuous bad weather have adverse effects on photovoltaic power plants?

The beginning of summer has arrived, and the rainy season in the south has arrived. After the May Day holiday, the cold air began to affect the northern regions of my country, the rain gradually increased, and the local temperature in the Northeast and North China exceeded 10 °C. At the same time, heavy rainfall in the south also unfolded, with torrential to heavy rains appearing in parts of Guangdong, Guangxi and other places. In severe weather with strong humidity, frequent rainfall and thunderstorms, if the photovoltaic power station is not systematically operated and maintained, it is often easy to cause potential safety hazards. How to deal with it?

What is the impact of photovoltaic grid connection on the grid?

With the continuous improvement of social economy, people's living standards are gradually improving, and the demand for electricity is also gradually increasing. Such demand has brought huge pressure to our country's power supply system. Although some new power generation energies are constantly being discovered, the uncontrollability of new energy power generation will have a great impact on the power quality in the power grid, so it is necessary to conduct further research on the power quality problems caused by the access of new energy sources In order to ensure the stable operation and reliability of the new energy power generation system. Therefore, the relevant departments and relevant staff should pay attention to the work research in this area.

How do solar cells work?

Solar cells are made up of silicon atoms. Think of atoms as building blocks—like Lego blocks, but because of their small size, you need special tools to see them. The solar cells are derived from layers of silicon wafers that are about the size of a dinner plate, but much thinner—only about three times thicker than an average human hair.
