Solar street lights use solar power to provide electricity for street lights. During the day, they absorb solar power and converted it into electrical energy to store it in the battery.
At night, it supplies electricity to the street light source through the battery discharge. Most parts of the country are about to fall across the rainy season in June, and continuous overcast days will decrease the efficiency of solar power conversion to electrical energy.
How can we guarantee the power supply to the street light source? What are the main reasons for the overcast days that cause the solar street light unable to light up?
First of all, it is necessary to consider the solar street light design at the early stage according to local weather, environment, temperature, and other conditions in order to configure the solar street lights reasonably.
Before the continuous rainy days come, it is needed to design the electricity and battery that converted by the solar panel can fully satisfy the power supply to the light source on the rainy days.
However, many manufacturers do not reasonably allocate according to the local lighting characteristics in actual use, and the fact that customers are blindly pursuing the low-cost leads to the configuration reduction, which will result in the shortage of power supply on the continuous overcast days.
Second, if the light base of solar street lights is not waterproof, the light base will be water damaged. In addition, it is common to replace the LED light source with an inexpensive light source, which also causes the light to burn out in overcast weather.
Third, if its controller is damaged. Waterproof quality will directly influence the service life of the controller. If the waterproof performance is poor, it will cause direct water damage to the controller. Charge-discharge process and lighting condition of solar street lights rely on the controller to finish; therefore, it is necessary to use its controller with absolute waterproof capability.
Fourth, line abrasion, poor contact, and short circuits will occur during the construction process of traditional solar street lights. If the integrated solar street lights are used, all the lines are in the light base, which does not cause problems such as poor contact and short circuit.
Fifth, the battery was damaged. During the installation process, in addition to its waterproof capability, the battery will be buried underground to avoid the water. The waterproof capability will be greatly reduced if it is shallowly buried and scrapped in serious cases.
Sixth, the installation position of solar street lights is unreasonable. There should not have a blockage above the solar panels, and no tall trees and buildings are surrounded, as these objects will have shadows and affect the solar panel to absorb light energy. In the long term, batteries will be electricity deficit and affect their use in overcast weather.
In summary, there are many reasons that cause the lights not able to operate properly on the continuous overcast days. Every subtle factor can result in the failure illumination of the lights, serious damage to the co accessories, and maintenance issues increases. Therefore, the cost, installation, stability, and service life must be taken into account when selecting the solar street light, which will provide convenience and continuity for the use of solar lights in the future.
