We all know that a complete solar street lamp consists of five main components: lamp pole, light source, battery, solar panel, and controller, along with components like ground cages, wires, and solar panel brackets. To determine the quality of the solar street lamp system, we can assess the solar street lamp’s battery components, light source, and controller.
First: LED Light Source
The efficiency of the LED beads used in solar street lamps is crucial. Although some LED beads can meet certain wattage, they may not achieve the expected light efficiency. When selecting LED beads, it is important to choose high-quality ones that can improve light efficiency, reduce light decay, and possess high color rendering properties. The heat sink of the solar street lamp light source is an important factor in extending the lifespan of the LED light source and reducing light decay. Poor heat dissipation can significantly shorten the life of the light source.
Second: Battery
When choosing batteries for solar street lamps, it is advisable to opt for high-quality lithium batteries or gel batteries. Some manufacturers may use inferior batteries that do not meet lifespan expectations. Batteries of a certain capacity have corresponding weights; weighing the solar street lamp battery can help in selection. If there is a significant weight difference, the battery should not be chosen.
Third: Solar Panel
The quality of solar panels used in solar street lamps is difficult to assess visually, but we can check their sealing, craftsmanship, glass thickness, and aluminum frame quality. Some unscrupulous vendors may use substandard tempered glass and thinner aluminum frames for solar panels, which makes them more susceptible to damage during transportation and less durable against hail, potentially allowing water ingress during use. Therefore, we must pay attention to these factors when selecting solar panels.
Fourth: Controller
The controller in a solar street lamp is a small component, but its function is akin to that of a brain. The quality of the controller directly affects the operation of the solar street lamp and can influence the lifespan of other components. Furthermore, during repair, the probability of issues arising in the controller is higher than in other components.
The quality of solar street lamps is determined by their configuration. We should not choose without purpose when purchasing; we must meticulously check the quality of each component to ensure the solar street lamp operates effectively.
