The Impact of Low Temperature in Winter on Solar Street Lights and Warming Tips
Oct 12, 2024
In cold winter, as the temperature continues to drop, solar powered outdoor street lights face many challenges, such as freezing of batteries and insufficient power generation. Especially in icy environments, some parts of solar street lights may be affected. To ensure that solar street lights can work normally in the continuous low-temperature climate in winter and provide people with stable lighting services, we can take appropriate warming and protective measures to ensure the normal operation of solar led street lights.

Solar panels are the core components of solar street lights, and their power generation efficiency directly affects the lighting effect of solar led street lights. As the height of the sun changes in winter, the angle of the solar panels should be adjusted in time to make them as vertical as possible to the sun's rays, so that they can receive the sun's rays to the greatest extent, increase the power generation of the solar panels, and ensure that the batteries can be fully charged.
For areas with severe snow accumulation, you can consider installing transparent electric heating films on the surface of solar panels. When snow covers the solar panels, the electric heating film is activated for heating, so that the snow melts and flows away naturally.

Increase battery capacity: Increase the capacity of the battery so that it can maintain a longer discharge time in winter.
Increase photovoltaic panel power: Use higher-power photovoltaic panels to improve power generation efficiency and ensure that the lighting needs of solar street lights can be met even when there is insufficient light in winter.
Strengthen insulation: Insulate the key parts of street lights, such as lamps and wires, such as wrapping insulation materials or using heating devices to prevent freezing due to cold. Regularly check whether the junction box and wires have broken or exposed parts, and repair them in time to prevent snowwater from seeping in and causing short circuits or damage.

Regular inspections: The weather changes greatly in winter, and solar powered LED street lights facilities need to be inspected regularly to find and solve existing problems in a timely manner. The inspection content includes but is not limited to the integrity inspection of facilities such as lamps, wires, control boxes, etc., as well as whether the fasteners are loose and whether the lubricated parts need to be refueled. Through timely maintenance and inspection, the normal operation of solar powered LED street lights in winter can be ensured and their service life can be extended.
Although the temperature difference and climate changes have been taken into account when designing solar street lights, proper warmth and maintenance of solar powered LED street lights in the continuous low temperature winter can effectively extend the service life of solar street lights so that solar street lights can provide people with continuous and stable lighting in extremely cold weather conditions and add a safety guarantee for people's travel.
* Strengthen the warmth of batteries
1. Increase the buried depth of batteries.
In the cold winter, the batteries of solar street lights are very susceptible to low temperatures, resulting in insufficient discharge and slow charging. Solar street light manufacturers recommend that in cold areas, the buried depth of batteries should be at least one meter, and 20 centimeters of sand can be laid on the bottom, which is not only conducive to the insulation of the battery but also helps the accumulated water dissipate, thereby extending the service life of the battery.2. Use insulation materials.
For the exposed battery parts, insulation materials such as insulation cotton can be used to wrap them to reduce heat loss. The selection of insulation materials should take into account their weather resistance and fire resistance. These materials can effectively isolate the external cold air, keep the temperature inside the battery relatively stable, and ensure that solar led street lights can still work normally in bad weather.* Pay attention to the installation angle and cleaning and maintenance of solar panels.
1. Adjust the angle of solar panels in time.
Solar panels are the core components of solar street lights, and their power generation efficiency directly affects the lighting effect of solar led street lights. As the height of the sun changes in winter, the angle of the solar panels should be adjusted in time to make them as vertical as possible to the sun's rays, so that they can receive the sun's rays to the greatest extent, increase the power generation of the solar panels, and ensure that the batteries can be fully charged.2. Clean up snow and dust regularly.
Snowfall is frequent in winter, and snow will cover the solar panels, affecting their ability to absorb sunlight. Therefore, it is necessary to regularly clean the snow and dust on the solar panels to keep their surface clean. Manual or mechanical methods can be used for cleaning to ensure that the solar panels can receive sunlight normally.
3. Install snow melting devices.
For areas with severe snow accumulation, you can consider installing transparent electric heating films on the surface of solar panels. When snow covers the solar panels, the electric heating film is activated for heating, so that the snow melts and flows away naturally.* Improve the configuration of solar powered outdoor street lights.
Increase battery capacity: Increase the capacity of the battery so that it can maintain a longer discharge time in winter.
Increase photovoltaic panel power: Use higher-power photovoltaic panels to improve power generation efficiency and ensure that the lighting needs of solar street lights can be met even when there is insufficient light in winter.
*Strengthen the antifreeze and maintenance of solar powered outdoor street lights facilities.
In addition to keeping the batteries and solar panels warm and optimizing them, the entire solar street light facility also needs to be antifreezed and maintained.Strengthen insulation: Insulate the key parts of street lights, such as lamps and wires, such as wrapping insulation materials or using heating devices to prevent freezing due to cold. Regularly check whether the junction box and wires have broken or exposed parts, and repair them in time to prevent snowwater from seeping in and causing short circuits or damage.
