How long can a 200W BC solar module be used? This depends on the material of the 200W BC solar module. Firstly, if the surface material is PET, it is approximately 3 to 5 years; ETFE is about 5 to 6 years; and glass is about 20 to 25 years. The years mentioned here do not mean that it stops working at this time. The usage time of the 200W BC solar module will decrease as its conversion efficiency decays. It may still be working after reaching these years, but compared with before, the power generation efficiency will only be reduced to 10-20%.

It was previously studied that solar panels naturally generate less electricity over time. This reduced power output is called the degradation rate. The median degradation rate of solar panels is approximately 0.5%, which means that the power generation of solar panels will decline at a rate of 0.5% per year.

There are various ways to enhance the power generation efficiency of solar panels and extend their service life. Some of these methods include:

Reduce the use in extreme weather. Both excessively high and low temperatures can damage the internal structure of solar panels to a certain extent. Keep the surface of the 200W BC solar module clean and tidy. There should be no fragments or destructive materials on the surface, otherwise it is easy to cause scratches and affect the power generation efficiency of the 200W BC solar module. The accumulation of dirt, pollen, leaves and bird droppings can affect the efficiency of your solar panels. Although rainwater is usually sufficient to clean your solar panels, if you find that your panels are not working at full capacity, you may need to consider professional cleaning.

Make sure your solar panels are regularly monitored and maintained. Regular maintenance checks will help keep the performance of your solar system's panels, meters, inverters and other components running at maximum efficiency. Material selection: Choose a suitable 200W BC solar module material. Good quality ensures long-term use.
