Three reasons for the reduced life of solar panels
Improving and guaranteeing the life of solar panels has always been one of the joint efforts of major solar panel manufacturers. However, due to some objective reasons, the lifespan of solar panels is limited, resulting in a decrease in the use time of solar panels. Big manufacturers have a headache. Let me introduce to you what causes the life span of solar panels to be reduced:
1. In the early stage, the output power of the photovoltaic module will reduce the life of the solar panel, mainly because the output power will be greatly reduced when used in the first few days, and the light and current injection into the silicon wafer due to stable use in the later stage will also cause Life expectancy is reduced. In the other stage, the main reason is that the performance of the battery has been reduced, which has affected the solar panels, and the other is the performance of the packaging materials.
2. The quality of silicon wafers. In the early days, the poor quality of the packaging materials used for solar panels resulted in unqualified silicon wafers. Unqualified silicon wafers would directly affect the service life of solar panels.
3. Hot spots, during the use of solar street lamp panels, under the sun's rays, some parts of the solar panels are blocked and cannot obtain solar energy, resulting in excessively high temperature in this part, which will cause burnout and darkening. Spots, the most deadly of such hot spots is to directly damage the entire solar cell module, so the solar cell panels must be maintained and cleaned frequently.
