What Should I Do If the Power Generation of Photovoltaic Power Plants Suddenly Declines?

Generally speaking, spring and autumn are the peak seasons for photovoltaic power generation, and winter is the low tide season for photovoltaic power generation. In addition to the shortened sunshine duration in winter and the weakening of sunlight, there are several reasons for reduction of the power generation of photovoltaic power plants in winter.

1. Haze and dust

When there are many suspended particles in the air, the suspended particles in the air will absorb and reflect sunlight, resulting in a significant reduction in the sunlight received by the surface of the module. If the sandstorm or haze weather persists, the accumulation of particulate matter on the surface of photovoltaic modules will form a shield on the surface of the modules, causing surface pollution of the battery modules and further reducing the energy of daze. According to relevant research, the daily power generation of photovoltaic modules after scrubbing will increase by 50%. Therefore, the frequency of scrubbing can be appropriately increased according to the site conditions, but frequent cleaning will also cause waste of water resources. The solar power remote monitoring system developed by our company will alarm you when the photovoltaic panels need to be cleaned according to power generation of panels.

Keeping the photovoltaic panels clean can not only increase the power generation, but also effectively maintain the photovoltaic modules, because the long-term accumulation of particulate matter may cause a lot of heat in the modules, resulting in hot spots, which may reduce the service life of modules, and even cause fire.

The operation and maintenance are in place, not only the power generation is high, and the income is guaranteed, but also the probability of failure can be reduced. Once a problem occurs, it can be discovered and solved in time. In addition, through our solar power remote monitoring system, you can check whether the photovoltaic power station is running normally anytime and anywhere, and problems will be solved, which is very convenient.

2. Shadows

Many walls, utility poles, vegetation and other objects have elongated shadows in winter, which can easily block photovoltaic modules. This is also the most easily overlooked problem in the construction of photovoltaic power plants in summer.

The shaded part not only does not generate electricity, but also becomes a source of resistance heating, reducing power generation, and long-term heating will cause damage to the battery cells, and may even cause a fire.

If this is the case, consider whether it is possible to remove the obstructing object or find an installer to see if the obstructed photovoltaic modules can be relocated.

3. Snow

Only a small amount of sunlight can pass through the snow and hit the PV modus when snow covers the modules and affect the photovoltaic power generation.

1) If your solar panels were installed in the area always snows, you should install your panel at a lager angle within the optimal inclination angle, which can reduce the accumulation speed of snow and save the trouble of cleaning snow from time to time.

2) Keep the component some distance from the ground when installing.
