3 Critical Factors Affecting Solar Panel Efficiency

Renewable energy sources have been an affective partner for the last few decades. Businesses and industries are rapidly switching toward the use and installation of solar energy. There are several reasons behind this fact. The average efficiency of a solar panel is 15% to 25%. However, solar panels with 40% efficiency are branded and a bit more costly than the other brands.

Many factors are responsible for the increase and decrease of the working of the solar system. Solar panels are sized and numbered based on the system's size. Panels should maintain about 25% capacity even during cloudy days. Here are some factors affecting the efficiency of solar panels.

Factors affecting the efficiency of solar systems:

1.     Shading

Solar energy operates by the absorption of solar rays. So, while installing the solar panels, it is critical to place the solar panel at a shadeless point. Shades decrease the efficiency of the solar system, as they block the passage and absorption of the solar rays.

2.     Weather

Solar panels can be adversely affected by extreme weather conditions. Specific temperatures have been found to optimize the performance of solar panels. Solar panels are thought to be more efficient at high temperatures. Instead, it may impede your system's performance and even result in damage.

3.     Clean your solar panels

Solar panels don't require a lot of maintenance since they don't contain any moving parts. Cleaning solar panels occasionally is a good idea, as dirt and dust can accumulate on the surface, reducing their efficiency.

Approximately 5% of output may be reduced as a result of dust and dirt over the course of a year. The output decline can, however, be greater than 20% if they become very dirty - perhaps in an area that does not receive regular rainfall. Therefore, cleaning your solar panels once a year is a pretty good idea.

Conclusion

Payback periods and energy independence are affected by the efficiency of solar panels. To prevent unnecessary disruptions, you should make sure that the system is in top shape. Solar panels have an efficiency of 25 percent during cloudy days if they are in good condition.
