In recent years, with the rapid development of the solar power generation industry, the field of photovoltaic applications is gradually expanding, and various new photovoltaic products are continuously emerging. Among them, solar street lights, which integrate technology and art in solar lighting systems, have begun to be widely used in many areas. So what are the tips for purchasing solar street lights? Here is an introduction from the editor of Century Sunshine Lighting.
1. Selection of Light Poles
The height of light poles typically ranges from 4 to 12 meters. When choosing their height, it is generally determined based on the width of the road and the power of the LED light source. If installed on one side only, the height should generally be less than the road width by 1 meter. The corresponding heights of the light poles for LED power outputs of 30-60W, 60-100W, 100-150W, and 150-200W are respectively under 6 meters, under 8 meters, under 10 meters, and over 10 meters. Therefore, when selecting the height of solar street light poles, it should be based on actual conditions. The poles for solar LED street lights should be sturdy enough to support their weight and ensure they remain upright even in severe weather conditions like typhoons.
2. Selection of Light Heads
The light heads of solar street lights generally use LED light sources, which convert light-emitting diodes into light energy. Compared to sodium lamps and metal halide lamps, they have a longer lifespan and are more energy-efficient and environmentally friendly. A closer observation will reveal many beads on the LED lamp; each bead represents one watt, and the more beads, the higher the wattage. Thus, this can be used to identify the wattage of the LED lights.
3. Selection of Solar Panels
Solar panels consist of several silicon crystal material cells, and their function is to directly convert solar energy into electrical energy. The size of the solar panels will influence the amount of electricity stored in the solar batteries. The surface area of the silicon crystal cells is directly proportional to the power of the solar panel, so it is crucial to consider this when purchasing solar panels.
4. Selection of Solar Storage Batteries
Solar storage batteries are used to store the electrical energy generated by the solar panels and provide it during cloudy days. Currently, there are a variety of batteries available on the market, such as lithium batteries and lead-acid batteries. However, lithium batteries have significant environmental pollution issues, while lead-acid batteries have a shorter lifespan and lower safety. Therefore, developers have created gel batteries based on lead-acid designs, which not only have a longer lifespan but also offer energy and power about 20% greater than lead-acid batteries. They can function well in both extreme heat and cold, and have a high safety factor. Consequently, gel batteries are now widely used by many solar light manufacturers.
The above tips for purchasing solar street lights are shared here. In summary, there are many good purchasing techniques for solar street lights, and all components must be of high quality in order for the overall effectiveness of the solar street light to be enhanced.
