Series Rifle solar powered street lamp for crossroads lighting in Bulgaria

Solar street lighting project in Bulgaria finished in 2021 with 70 sets of 44W solar powered street lamps. The customer chose our Rifle series led street lamp head, high-quality solar polycrystalline panel, no-maintenance lead-acid battery, solar charger, and pole with battery box which is used for crossroads. Typically 50% less expensive to install than traditional outdoor solar light solutions. Now the customer is very satisfied with this project which not only lowers their reliance on local electricity but is also maintenance-free. New projects are coming soon.

Solar street lights are solar-powered street lights that are installed on street poles. Solar street lighting is both inexpensive and ecologically friendly. It saves communities money on energy costs and mitigates the dangers connected with dark roadways.

Disadvantages. The initial cost is more than that of standard street lighting. The risk of theft is increased due to the relatively high cost of equipment. Snow and dust, when mixed with moisture, may collect on horizontal photovoltaic panels, reducing or even completely shutting down electricity output.

The primary distinction between solar powered led street lights and conventional street lights is that solar powered street lamp are powered by solar energy. Solar energy is extensively employed in a variety of businesses due to its environmental friendliness and renewable nature. Solar-powered led street lights are an example of effective solar energy uses. Solar-powered led street lights consist mostly of solar panels, controllers, batteries, and light sources. It can be divided into split LED solar street lights and all-in-one LED solar street lights. Due to its ease of maintenance and cheap cost, solar street lighting is extensively employed in sparsely inhabited rural regions. However, some individuals question if solar-powered led street lights are indeed convenient to maintain. In this essay, we'll discuss some of the fundamental issues and solutions surrounding solar-powered led roadway lighting.

  1. The whole street light is not working.

Due to the fact that solar-powered led street lights are used for outdoor illumination, they are often exposed to extreme heat, rain, cold, and other environmental conditions. Typically, the solar street light controller is mounted on the light pole. When it rains, it is quite simple for water to enter and short-circuit the controller. We may begin by determining if there is an issue with the controller's terminal. If the controller is destroyed, verify that the battery board produces voltage and current while it is operating properly. Replace the battery board if there is no output.

  1. The solar-powered led street light does not provide enough light.

To begin, inspect the LED light source for quality and for any issues with the chips' fake welding. Numerous solar-powered led street lights make use of dot-matrix LED lighting. Along with the LED light source's quality, this issue is caused by some insufficient chip welding. The remedy is to repair the matching chips, reinforce the weld, or completely replace the street light head. If not, it is possible that the amount of sunshine available at the installation site is inadequate and the lighting design is not suitable.

  1. The street light head flashes

This condition might be the result of insufficient line contact, battery power loss, or a significant drop in power storage. If there are no issues, the battery is defective and must be replaced.

  1. Short working time

If it is raining, the illumination will be brief. Generally, it is caused by a decline in the battery's storage capacity and inadequate power. Simply change the battery.

  1. Solar panels that have been damaged

Determine the solar panel's open-circuit voltage. Solar panels are not linked to any load in the sun and are also disconnected from the controller. Directly disconnect the solar panel's cables and attach a multimeter to test the panel's voltage. Under typical conditions, the solar panel's voltage will be more than 12V. It can charge the battery only when the voltage is more than 12V. If the battery voltage is less than 12V, it cannot be charged. If the solar panel's voltage is less than 12V, it should be replaced.

In summary, there are several causes for solar-powered led street lights to fail. When an issue develops, it must be examined promptly in order to determine the origin of the problem and to resolve it in a focused way. If you are unsure how to spot difficulties, you may contact a reputable solar street light manufacturer who can help you minimize the likelihood of secondary maintenance. Additionally, we would like to remind everyone that when buying solar-powered led street lights, it is critical to get branded, high-quality items to ensure that the lights operate reliably. Even in the event of a failure, the producer of solar street lamps may give excellent after-sales care.
