solar street lighting system is composed of eight elements. That is, solar panel, solar battery, solar controller, main light source, battery box, main lamp cap, lamp pole and cable.
solar street lighting system refers to a set of independent distributed power supply system constituting solar street lamps. It is not subject to geographical restrictions, is not affected by the location of power installation, and does not need to excavate the road surface for wiring and pipe laying construction. The on-site construction and installation are very convenient. It does not need power transmission and transformation system and does not consume municipal power. It is not only environmental protection and energy saving, but also has good comprehensive economic benefits. In particular, it is very convenient to add solar street lamps to the built roads. Especially in road lights, outdoor billboards and bus stops far away from the power grid, its economic benefits are more obvious. It is also an industrial product that China must popularize in the future.
System working principle:
The working principle of the solar street lamp system is simple. It is a solar panel made by using the principle of photovoltaic effect. During the day, the solar panel receives solar radiation energy and converts it into electric energy, which is stored in the battery through the charge discharge controller. At night, when the illumination gradually decreases to the set value, the open circuit voltage of the sunflower solar panel is about 4.5V, After the charge discharge controller automatically detects this voltage value, it sends out the braking command, and the battery begins to discharge the lamp cap. After the battery is discharged for 8.5 hours, the charge discharge controller sends a braking command, and the battery discharge ends.
