1. Choose light source: Solar street lamps generally adopt LED light source, and most of them use 1W high-power lamp beads. Generally, the power of one lamp bead is 1W, and the number of lamp beads is the number of watts.
2. Panel: Solar street lamp panels generally use single crystal and polycrystal, the price of single crystal is higher than polycrystal, general customers choose and buy if there is no professional measuring instrument, it is recommended to use the size area to measure, the larger the size area, the larger the size of the panel is proportional to the power of the panel.
3. Batteries: Solar street lamp batteries are generally divided into lead-acid batteries, colloidal batteries and lithium batteries. Currently, colloidal batteries and lithium batteries are commonly used, and the cost of lithium batteries is higher than colloidal batteries, which is higher than lead-acid batteries.
4. Lamp pole: The height, shape and parameters of the lamp pole are mainly considered. The higher the height of the lamp pole, the corresponding parameters should be increased and the price will also be increased.
