Solar powered street lamp is a popular outdoor lighting product powered by solar energy. It composed of light source, controller, solar panel, battery, etc. Solar panel absorbs the solar energy and transfer the energy into electricity, store the electricity in the battery. For off-grid areas such as some countries in Africa, the solar powered street lamps are favored by most people. Africa is near the equator, the solar energy is abundant. Using solar powered outdoor street light, there are no electricity bills. However, some people find the street lights become dim and not bright as before.What's the reasons and how to solve this problem? Let's read this article to find the answer.
Reasons why solar powered street lamps are not bright enough
1. Battery aging
The battery is the place where solar powered street lamps store electricity. If the battery is aging and damaged, there will be no electricity storage, so the solar powered street lamps will have no electricity supply, or there will be a weak electricity supply, which will cause the street lamps have insufficient brightness.
2. The solar panel power is too low
When the solar powered street lamp is designed and configured, if the power of the solar panel is too small, it will cause insufficient storage of the battery. When in use, the outdoor solar street light consumes too much power and the battery can't supply power, so the lamp is not bright enough.
3. Weather effects
The weather has a great influence on solar powered street lamps. Solar powered street lamps absorb sunlight during the day and convert electricity to store electricity, and at night use the electricity stored during the day. If there is no sunlight for many consecutive days, it is cloudy or rainy and snowy, then the street lights will lose the source of power. Solar powered street lamps always use the stored power. When the stored power is used up, or when it is getting less and less, the light emitted by the street lamps will be very weak, which will cause insufficient light.
4. The setting of the controller
The solar controller is used to control the lighting hours and brightness. If the setting of the solar road lamp controller does not match the actual local conditions, especially in some rainy places, it will cause the brightness to decrease. If the number of local rainy days often exceeds the setting of the controller, it will bring a great burden to the battery, cause the battery to age and shorten the service life. The common problem is that the solar powered street lamp is not bright enough.
5. The influence of external factors
Large trees were planted near the solar powered street lamps, which blocked the sun's light source, which would cause the solar panels to fail to absorb sufficient sunlight. It may also be because the orientation of the solar panels is inconsistent with the direction of sunlight, so the efficiency of solar panels in absorbing solar energy is reduced. Without sufficient power, the brightness of solar powered street lamps is naturally not enough.
Solutions for insufficient brightness of solar powered street lamps
1. Increase the output power
If the solar powered street lamp does not look bright, you can increase its output power so that the street light will be brighter, but it should be adjusted according to the actual use.
2. Pay attention to the direction and position of the solar panel
China is in the northern hemisphere, so solar light basically shines from a southerly angle. Therefore, the solar panels should face south, and are generally installed in a place where there is direct sunlight throughout the day. The shadow of tall buildings or trees will have a great impact on the work of solar panels.
3. Use more efficient LED lamp beads
Solar powered street lamp beads are also very important. If the efficiency of the lamp beads is low, it will cause insufficient street lighting. When configuring solar powered street lamps, use high-efficiency lamp beads to increase brightness as much as possible.
4. Pay attention to the tightness of the battery and set the controller correctly
The battery of the solar powered street lamp is generally buried in the ground, if the battery sealed box with good sealing performance is not used when it is buried in the ground. Or the battery box is damaged under certain circumstances and loses its sealing performance, it is easy to cause the battery to age or malfunction. Only by sealing well can the normal use be ensured and sufficient brightness can be ensured. When setting the controller, it should be set according to the different climates and lighting hours in different regions, so as to ensure normal use.
