Detailed explanation of technical requirements for photovoltaic solar panels

1. Material requirementsPhotovoltaic solar panels are devices that utilize the photoelectric effect of semiconductor materials to generate DC power through solar radiation. Therefore, key materials for photovoltaic solar panels should include cells with high efficiency, good durability, and anti-aging properties, transparent packaging materials, conductive glue, etc. Cells should have excellent electrical and mechanical properties and be able to work stably and permanently under complex outdoor conditions.

2. Efficiency requirements

The efficiency of photovoltaic solar panels refers to the rate at which it converts solar radiation into electrical energy, which directly affects the power generation capacity and economics of photovoltaic power stations. Therefore, high efficiency is an important development direction of photovoltaic solar panel technology. At present, the efficiency of monocrystalline silicon photovoltaic cells has exceeded 22%, while the efficiency of polycrystalline silicon photovoltaic cells has also exceeded 20%, and there is still room for improvement in the future. At the same time, on the premise of ensuring efficiency, attention must also be paid to the control of costs and manufacturing processes.

3. Durability requirementsThe service life of photovoltaic solar panels is closely related to their durability. Whether photovoltaic solar panels can work normally and maintain high efficiency for a long time under harsh conditions such as different climates, strong ultraviolet rays, strong winds, hail, dust, etc. is a core indicator of their durability. Therefore, one of the important technologies of photovoltaic solar panels is their durability. They should have the characteristics of high strength, good protection, safety, reliability, etc., be able to adapt to various harsh environments for a long time, and be able to operate for a long time.

4. Other requirements

In addition to the above requirements, photovoltaic solar panels also need to pay attention to the following technical requirements:

1. The site layout is reasonable to maximize sunlight reception;

2. User-friendly design for repair and maintenance;

3. Comply with new energy policies, standards and specifications, based on complete regulatory compliance design;

4. Excellent energy-saving design and multiple safety measures, such as over-voltage protection, anti-reverse current protection, anti-lightning protection, etc.

In short, photovoltaic solar panels, as an emerging clean energy technology, have broad application prospects. Understanding the technical requirements of photovoltaic solar panels provides strong support for promoting the development of high efficiency and reliability and promoting clean energy networks.
