Solar cell components, also called solar panels and photovoltaic components, are the core part of the solar power generation system and the most important part of the solar power generation system. Their function is to convert solar energy into electrical energy, or to store it in cells, or to drive it. load work.   Solar cell modules are composed of high-efficiency monocrystalline or polycrystalline solar cells, packaging materials (EVA, POE, etc.), functional backsheets, interconnection bars, bus bars, junction boxes and aluminum alloy frames .     The principle of solar cells   The energy converter of solar photovoltaic power generation is solar cells, also known as photovoltaic cells. The principle of solar cell power generation is the photovoltaic effect. When sunlight shines on a solar cell, the cell absorbs light energy and generates photogenerated electron-hole pairs. Under the action of the built-in electric field of the cell, the photo-generated electrons and holes are separated, and there is an accumulation of charges of different signs at both ends of the cell, which generates a "photo-generated voltage". This is the "photovoltaic effect". If electrodes are drawn out on both sides of the built-in electric field and a load is connected, a "photogenerated current" will flow through the load, thereby obtaining power output. In this way, the sun's light energy is directly converted into usable electrical energy.   At the same temperature, the impact of light intensity on solar panels: the greater the light intensity, the greater the open circuit voltage and short circuit current of the solar panel, and the greater the maximum output power. At the same time, it can be seen that the open circuit voltage changes with the irradiation intensity. It is not as obvious as the change of short-circuit current with irradiation intensity.   Under the same light intensity, the effect of temperature on the solar panel: When the temperature of the solar cell increases, its output open-circuit voltage decreases significantly with the temperature, the short-circuit current increases slightly, and the general trend is that the maximum output power becomes smaller     Characteristics of solar cells   Solar cell modules have high photoelectric conversion efficiency and high reliability; advanced diffusion technology ensures uniformity of conversion efficiency throughout the chip; ensures good conductivity, reliable adhesion and good electrode weldability; high precision high flatness make the cell easy to automatically weld and laser cut.   According to the different materials used, solar cells can be divided into: silicon solar cells, multi-compound thin film solar cells, polymer multi-layer modified electrode solar cells, nanocrystalline solar cells, organic solar cells, plastic solar cells, among which silicon solar cells are the most mature and dominate applications.

Nowadays, many people choose solar photovoltaic power generation for their home electricity. The use of  photovoltaic power generation is not only clean and environmentally friendly, but also saves energy and electricity bills. We all know that photovoltaic power stations are high-quality, high-value, and high-demand products. It  can not only ensure the power generation of the power station, but also extend its service life when using the solar panels correctly. Therefore, maintenance after the power station is installed is particularly important. Today our article also focuses on the topic of how to maintain and maintain solar panels in photovoltaic power stations.   1. Regular cleaning of solar panels is a crucial step Since solar panels are usually installed outdoors, they will be affected by various natural environments, such as dust, leaves, bird droppings, etc. These impurities will affect the light absorption efficiency of the solar panel, so the solar panel should be cleaned every once in a while. You can use a soft brush, detergent and water to ensure cleanliness, and allow adequate drying after cleaning to prevent water stains from remaining. Never clean with corrosive solvents or wipe with hard objects. When there is snow in winter, it should be cleaned up in time.   2. Check whether the solar panel brackets and connecting parts are firm, regularly check whether the metal brackets of the solar panels are corroded, and regularly paint the brackets for anti-corrosion treatment Solar panels are usually installed on the ground or roof through brackets. Regularly check whether the connecting parts of the bracket are loose or corroded to ensure the stability and safety of the solar panels. Special attention needs to be paid to timely inspection and maintenance during extreme weather conditions, such as storms, earthquakes, etc.   3. Monitor and maintain electrical systems In addition to solar panels, a solar power station also includes electrical components such as inverters, batteries, and cables. Regularly check the operating status of these devices to ensure that cable connections are secure, the inverter is operating properly, and the battery is performing well. For equipment such as inverters, remote monitoring systems can be used for real-time monitoring to detect and solve problems in a timely manner.   4. Perform regular performance testing Through the LCD of the solar inverter, the power generation performance of the solar panels can be monitored in real time, abnormal conditions can be discovered in time and measures can be taken. This helps to improve the overall efficiency of the solar power plant and extend the life of the equipment.   5. Carry out regular professional inspection and maintenance After the equipment has been put into operation for a period of time, it is recommended to ask professionals for regular inspection and maintenance, conduct a comprehensive inspection of the equipment, and replace aging parts to ensure the long-term stable operation of the solar power station.   Proper maintenance of solar panels can ensure timely detection and resolution of faults and increase service life and power generation efficiency. Through these maintenance and upkeep measures, the efficient and stable operation of the solar power station can be ensured and the power generation potential of clean energy can be maximized.
