Reasons that Solar Street Lamps are Dim And Solutions

Street lights are indispensable infrastructures in urban construction, accounting for 40% of outdoor lighting. Research shows that more than 70% of the street lights currently used on the road are new energy street lights, and more than half of them are solar street lamps. Nowadays, solar street lamps are widely installed to illuminates the streets, roads and highways, and they also help reduce energy costs and cut carbon emissions. No manual switch is required. Although there are many advantages of solar street lamps, there are occasional accidents when using them, such as insufficient light during use, and the street lights become dim and no longer bright as usual. So what are the reasons for this situation? How can we solve it?

1. The reason why solar street lamps are not bright enough

Aging of battery

The service life of the battery should also be considered in the application of the entire street lamp system. The general battery is guaranteed for three or five years, but the general battery will be unsatisfactory after one year or even six months, and the actual charging rate may drop to about 50%. The battery is the energy storage place of the solar street lamp. If the battery is aging and damaged, there will be no power storage. In this way, the solar street lamp will only provide weak power, which will cause the solar street lamp to be insufficient or affect the normal night lighting during continuous rainy days. . Therefore, it is especially important to choose a better battery. The battery used in EXC solar street lamps is the most cost-effective lithium iron phosphate battery on the market. The number of charge and discharge can reach more than 1500 times, and the service life can reach more than 8 years. Solar street lamps with motion sensors have more advantages.

LED lamp bead decays too fast

Some street lamp manufacturers often choose LED as the lighting source of solar street lamps, but the quality of LED lamps is uneven, and the severely decayed LED may attenuate 50% of the illuminance in half a year. So be sure to choose an LED light source with a slower light decay. If the light source of the street lamp decays too fast, the street lamp will look very dark and not bright enough before long. EXC solar street lamps use imported brand light sources, with guaranteed quality, slow attenuation, and a life span of more than 50,000 hours.

Battery power is too low or the controller is not set properly.

When designing and configuring solar street lamps, if the power of the battery panel is too small, it will cause insufficient power storage of the battery. When in use, the street light consumes too much power and the battery can't supply power, which will cause insufficient light. The solar controller is to control the lighting time and brightness of the solar street lamp. If the setting of the controller does not match the actual local conditions, the brightness of the street lights with motion sensor will decrease. Especially when the number of local cloudy and rainy days often exceeds the setting of the controller, it will bring a great burden to the battery, cause the battery to age, and reduce the service life.

Weather influence

The weather has a great influence on solar street lamps. solar street lamps absorb sunlight during the day to convert electrical energy to store electrical energy, and use the electrical energy stored during the day at night. This will continue to cycle, but if there is no sunlight, cloudy or rainy for many consecutive days. In snowy weather, the street lamp will lose the source of power, so that when it is used, it will 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 solar street lamp will be very low.

Influence of external factors

If the solar street lamp has tall trees or buildings that block the sun's light source, it will cause the solar street lamp to not absorb enough sunlight, and there will not be enough electricity. It may also be because the orientation of the solar panel of the solar street lamp is problematic, and it is not facing the direction of the sunlight, so it does not absorb the sunlight. This situation may also cause insufficient brightness of street lights.

2. Solutions to insufficient brightness of solar street lamps

Let the technicians increase the output power according to the actual situation.

Set up the controller according to the specific conditions of the solar street lamp use area and the lighting requirements of the customer, so as to ensure the normal use

The use of high-efficiency LED lamp beads, the lamp beads of solar street lamps is very important. The low efficiency of the lamp beads can easily cause insufficient brightness.

Pay attention to the orientation and position of the solar panels. It is best to install solar street lamps 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. If there are tall buildings nearby, it is more appropriate to install solar street lamps on the southern side of the road.

Pay attention to the reasonable configuration and sealing of the battery. The configuration of the battery should be based on the customer's lighting needs, and the configuration cannot be reduced in order to reduce the price. The battery of solar street lamps is generally buried in the ground. If the battery seal box with good sealing performance is not used when buried in the ground, it will cause aging or failure. Only by sealing well can the normal use of the battery can be guaranteed.

The main reasons for the insufficient brightness of solar street lamps are the above. If after investigating the above reasons, the solar street lamp is still not bright enough, welcome to consult the professional solar street lamp manufacturer-EXC. We will provide you with professional advice.
