1. The brightness of solar street lamp becomes dim or does not light up
The continuous snowstorm will make the snow cover a large area or completely cover the solar panels. As we all know, the lighting of solar street lamps depends on solar panels to receive light and store electricity in lithium batteries through voltage effect. If solar panels are covered with snow, they will not be able to receive light and generate electricity. If the snow is not cleared, the power in the lithium battery of the solar street lamp will gradually decrease to no, which will cause the brightness of the solar street lamp to dim or even not light.
2. The stability of solar street lamps becomes worse
This is because some solar street lamps use lithium iron phosphate batteries, which are not resistant to low temperature and have poor stability in low temperature environment. This will happen because the continuous snowstorm will inevitably lead to a significant drop in temperature.
However, these are not the quality problems of solar street lamps themselves. You can rest assured. After the snowstorm, the above situation will disappear naturally.
Today, China's new rural construction project has entered the final stage. Solar street lamps do not need electricity, economic and environmental protection, and have certain economic benefits after long-term use. Therefore, they are vigorously used in rural areas. Today, solar street lamps have been installed in most rural areas of China.
With the arrival of winter, haze weather is frequent. Recently, haze has occurred in most parts of China. Haze is mainly composed of sulfur dioxide, nitrogen oxides and inhalable particles, which are combined with fog to darken and gray the sky instantly. So what impact will the continuous haze weather have on the use of solar street lamps? Next, the small series of solar street lamp manufacturers will briefly discuss this issue with you.
1. Solar street lamps are on for a short time, or even not on.
Cloudy weather is equivalent to rainy weather. If the solar street lamp configuration is not very high, the solar panel will be exposed to the sun in a short time and absorb little light energy, resulting in insufficient power of the solar cell. This will shorten the lighting time of solar street lamps. In the continuous haze weather, solar street lamps will not be lit.
2. Affect the charging efficiency of solar panels.
There is more dust in the air. After the haze weather, the surface of the battery panel will be covered with dust. In the continuous haze weather, more and more dust accumulates on the surface of solar panels, preventing solar cells from absorbing light energy, thus affecting power generation efficiency.
The continuous haze weather will cause the above two adverse effects on the use of solar street lamps, so how can we avoid it? Solar street lamp manufacturers give the following two suggestions:
1. In areas prone to smoke, solar street lamps with high configuration shall be selected as far as possible. High configuration and large battery capacity. Under the same light source power, the lighting time will not be shortened, and the continuous rainy days can be longer. Even in several consecutive haze weather, the light can be turned on normally.
2. In the continuous haze weather, the solar panel shall be cleaned regularly to remove the dust on the surface of the solar panel and avoid affecting the efficiency of solar panel absorbing light energy.
