The Operation and Maintenance of Solar Cells

The Operation and Maintenance of Solar Cells


The application of solar cells is becoming more and more extensive, and there are various types of solar cells with similar working principles, long service life, gradually improving conversion efficiency, easy transportation, and convenient installation, which have a good prospect. In recent years, with the continuous exploitation by human beings, traditional energy such as fossil energy has become less and less and pollutes the atmosphere. To alleviate the shortage of resources and the tension of energy use, people have begun to focus on wind energy, solar energy, biomass energy, hydro energy, geothermal energy, and tidal energy. Coupled with the implementation of measures such as encouragement from the government, green energy accounts for more and more in the energy structure.
 
China which is relatively rich in solar energy resources, gradually develops and utilizes them extensively. Direct and indirect utilization of solar energy resources is two ways of utilizing solar energy. Direct utilization includes photoelectric and photothermal conversion methods. Indirect utilization is a way that converts solar energy into chemical energy first, and then converts the latter into electrical energy or other forms of energy. Therefore, to relieve the pressure on traditional energy sources and reduce air pollution, the use of solar energy to generate electricity has also become a long-term research topic. At this stage, solar power generation mainly includes photothermal (converting light energy into thermal energy first, and then converting the latter into electrical energy) and photoelectricity (converting solar energy directly into electrical energy, that is, photovoltaic power generation). At present, the development speed, product sales volume, and follow-up development of photovoltaic power generation are relatively good.
 
1. Doing a good job in the cleaning and protection of photovoltaic modules
Solar cells run outdoors for a long time, and dust and fallen leaves cannot be avoided. Therefore, it is necessary to do a good job of cleaning. Regular cleaning of solar panel components (photovoltaic modules) can effectively improve power generation efficiency and even reduce the formation of hot spot effects. Gently clean the part and not apply too much force so as not to press or damage the module.
 
2. Doing a good job in the maintenance of photovoltaic modules
The maintenance of photovoltaic modules can effectively ensure the normal operation of the entire solar cell system. Check whether or not the solar panel is blocked or cracked, the encapsulation part is aging, the junction box is corroded and the connecting wire of the solar panel is aging and exposed. In the inspection process, once these problems occur, report, or replace the solar panels in time so as not to affect the operation of the entire power generation system.
 
3. Doing a good job of remote monitoring
Some solar power plants are built in remote places, even isolated islands and deserts. Regular human inspections are expensive. Therefore, it is particularly important to do a good job of remote monitoring of photovoltaic modules. We should not only monitor the appearance of photovoltaic module equipment, but also monitor the running status of data and transmission equipment from time to time.
 
4. Conclusion
As the core component of a photovoltaic power generation system, a solar cell is directly related to the operation and power generation efficiency of the entire photovoltaic system. Doing a good job in all aspects of solar cells from research and development, production installation to later maintenance can ensure the power generation efficiency of the photovoltaic system and reflect the green concept of energy conservation and emission reduction.
