In the process of photovoltaic power generation, the inverter, as one of the core devices, has many internal electronic components. When it continues to work, the heat will be collected inside the cavity, leading to higher and higher temperature.
Therefore, the installation position of the inverter should do a good job of shading and ventilation, to ensure air circulation and convection.
Because the wind in autumn is generally more than in summer, so in autumn, it is also conducive to the cooling of the inverter.
The Angle of PV module also has an effect on the power generation
The "dip Angle" refers to the Angle between the surface of the PV module and the surface water plane. The dip Angle and orientation of the module are also factors that determine the power generation. Generally speaking, module tiling is conducive to summer photovoltaic power generation, module tilt is
conducive to winter photovoltaic power generation.
In order to adapt to the light conditions throughout the year, the Angle will not be too small or too large, when the photovoltaic module installation will try to find the "best Angle". In this Angle, will be conducive to the four seasons of power generation.
Thus it can be seen
Hot summer weather is not conducive to photovoltaic power generation
The temperature is best in autumn
Hence the most efficient generation
Especially in the cool autumn
When the clouds are thin
Will make the photovoltaic power generation up! The
Precautions for cleaning photovoltaic equipment
Because the photovoltaic panel is exposed in the air for a long time, the panel will inevitably accumulate dust over time, affecting the power generation effect. So, what should we pay attention to when cleaning photovoltaic power generation equipment?
Let's study together!
Ensure personal safety and device safety
Because most of the household photovoltaic is installed on the inclined roof, when cleaning, it is necessary to avoid falling injury or sliding abrasion. If you have difficulties cleaning yourself, you can find professionals to clean.
In addition, because the photovoltaic equipment needs many brackets and screws to support and fix, attention should also be paid to not damage the support structure and cause safety risks when cleaning the components.
The best working hours to avoid photovoltaics
Attention must be paid to the selection of dust removal time. In the daytime, the sunlight is sufficient, the photovoltaic power generation equipment is in operation, and there will be high voltage in the equipment. The dust removal work should be avoided during this period. Therefore, it is recommended that you choose the morning before sunrise or evening after the sun goes
down to clean the work, if possible, it is best to power off the photovoltaic system to ensure safety.
Choose the right cleaning method
It is recommended to choose a soft brush or soft cloth together with special cleaning liquid to clean the panel in the case of eliminating the leakage danger. When cleaning, do not step on the panel, and do not spray cold cleaning liquid directly on the panel
when it is very hot. The intensity of cleaning is not too large to avoid damage to the surface.
