Lithium battery solar street Light mainly consists of solar panel, solar controller, lithium battery and light source. light source is an important index.

Solar panels are the core of solar streetlights and the most valuable part of solar streetlights. Its role is to convert the solar radiation capacity into electrical energy, or send it to the battery for storage. Solar cells mainly use single crystal silicon as a material. A P-N junction similar to that in a diode is made of monocrystalline silicon. The working principle is similar to that of a diode.

The most important part of solar light system is the controller, whose performance directly affects the life of the system, especially the life of the battery. The controller uses industrial MCU as the main controller. By measuring the ambient temperature, detecting and judging the parameters of voltage and current of storage battery and solar cell module, it can control the turn-on and turn-off of MOSFET devices and achieve various control and protection functions.

Battery. Generally there are lead-acid batteries, Ni-Cd batteries and Ni-H batteries. The choice of battery capacity generally follows the following principles: First, the energy of the daytime solar cell module is stored as much as possible while meeting the nighttime illumination, and at the same time, it is also necessary to store the electrical energy required for the nighttime rainy day. If the battery capacity is too small, it will not meet the needs of night lighting. If the battery is too large, the battery will always be in a state of power shortage, affecting the life of the battery, while causing waste.

Light sources. Generally, solar lights use low-voltage energy-saving lights, low-pressure sodium lights, electrodeless lights, and LED light sources.
