Shock! It turns out that solar street lights were chosen like this
LED light source: Solar street lights generally use LED light sources, and often use 1W high-power lamp beads. Generally, the power of one lamp bead is 1W, and how many lamp beads are how many watts. Method/Step
2: Solar panels: solar street lamp panels generally use monocrystalline and polycrystalline, and the price of monocrystalline is higher than that of polycrystalline. Generally, customers do not have professional measuring instruments to purchase. It is recommended to use the size area to measure and balance. The larger the size area, the larger the size of the battery panel is proportional to the power of the battery panel. Method/Step
3: Batteries: Solar street lamp batteries are generally divided into three types: lead-acid batteries, gel batteries and lithium batteries. Currently, colloidal and lithium batteries are commonly used. The cost of lithium batteries is higher than that of colloids, and the cost of colloids is higher than that of lead-acid batteries. Method/Step
4: Light pole: The height, shape and parameters of the light pole are mainly considered. The higher the height of the light pole, the higher the corresponding parameters and the higher the price. The more complicated the shape of the light pole, the higher the price. Precautions Do not buy solar street lights for cheap, or shop around.
