White snow, silver wrapped, auspicious snow heralds a bountiful year. Beijing, approaching Christmas, has been decorated in advance, dreamy yet full of hope.
But with the arrival of winter, the power generation of photovoltaic power stations will decrease. In addition to the reasons of light, there are also factors such as haze, snow, and low temperature. To ensure our power generation as much as possible, we need to do these works well.
1. Cleaning of photovoltaic modules
In winter, due to dry weather and heating, there will be relatively more haze weather. If the haze weather lasts for a long time and particulate matter in the air accumulates on the surface of photovoltaic modules, it will form obstruction, which may cause a hot spot effect, resulting in a decrease in power generation and even fire.
At this time, it is necessary to clean the surface of the photovoltaic module in a timely manner to avoid dust accumulation. It is recommended to use Multifit photovoltaic cleaning brushes, photovoltaic cleaning robots, and other equipment. If problems are found with photovoltaic modules, they need to be replaced in a timely manner.
2. Snow clearing
After snowfall, snowflakes cover the photovoltaic modules, reducing the solar radiation received by the modules, which directly reduces the photovoltaic power generation and may also cause hot spot effects. Therefore, it is necessary to clean up the snow in a timely manner.
When cleaning, do not wait for too much snow to accumulate before cleaning to prevent components from freezing. Do not use hot water to flush the photovoltaic panels. Use clean mops, soft items such as discarded clothing, etc. to push snow down, and do not step on the components to clean.
In addition, thorough snow removal is necessary. If residual snow covers the solar panel, it will cause the overall photovoltaic panel to fail and reduce power generation efficiency. For small-scale photovoltaic power stations for household use, the battery panels can be covered with cloth or plastic paper before heavy snow, and can be peeled off after snow.
3. Routine inspection of inverters
In low-temperature environments, common faults of inverters include: inability to start the inverter, damage to components or parts. Regular inspections can ensure the normal and stable operation of the inverter.
