1. Solar panels
The solar panel is the component that supplies energy for solar street lamps. Its function is to convert the sun’s light energy into electrical energy and transmit it to the battery for storage. It is the most valuable component in solar street lamps. Solar cells mainly use monocrystalline silicon as the material. In solar cells, it is solar photons and light radiation heat that drive and affect the movement of holes and electrons in the P-N junction, which is commonly referred to as the principle of photovoltaic effect. Now the power of photoelectric conversion is about 13 times the power of photovoltaic cells and about 13 %-15%, polysilicon 11%-13%. Now the latest technology also includes photovoltaic thin film cells.
2. Battery
The battery is the power storage of the solar street light, and the collected power supply is supplied to the street light to realize the lighting. Because the input energy of the solar photovoltaic power generation system is extremely unstable, it is usually necessary to equip a battery system to work. Usually, there are lead-acid batteries, Ni-Cd batteries, Ni-H batteries, the selection of battery capacity usually follows the following principles: First, under the premise of meeting the lighting at night, store the energy of the solar cell components during the day as much as possible, and at the same time, be able to store enough energy to meet the lighting needs of continuous rainy days at night electrical energy.
3. Control the inverter
The existence of the solar controller, its function directly affects the life of the system, especially the life of the battery. The controller uses an industrial-grade MCU as the main controller. Through the measurement of the ambient temperature, the voltage and current of the battery and solar cell components are measured. Check and judge, control the switching on and off of MOSFET devices, and achieve various control and protection functions.
4. LED light source
Which light source to use for solar street lamps is the main goal of whether the solar lamps can be used normally. Generally, solar lamps use low-voltage energy-saving lamps, low-voltage sodium lamps, electrodeless lamps, and LED light sources, and some use high-power LED light sources.
5. Lamp pole light stand
The street light pole device supports LED street lights.
