1. Solar panels
Solar panels are the components that supply energy to solar streetlights. Their function is to convert the solar energy into electrical energy, which is transmitted to a battery for storage. They are the most valuable components in solar streetlights.
Solar cells primarily use monocrystalline silicon as a material, and what drives and affects the movement of P-N junction holes and electrons in solar cells is the heat of solar photons and light radiation, which is commonly known as the photovoltaic effect principle.
The current power of photovoltaic conversion is approximately 13% -15% for monocrystalline silicon and 11% -13% for polycrystalline silicon. The latest skills now include photovoltaic thin film batteries.
2. Battery
Batteries are the power storage of solar street lights, and the collected power is supplied to the street lights to complete lighting. Due to the extremely unstable input energy of solar photovoltaic power generation systems, it is usually necessary to equip a battery system for operation, usually including lead-acid batteries, Ni-Cd batteries, and Ni-H batteries.
3. Control inverter
The existence of solar energy controllers directly affects the lifespan of the system, especially the lifespan of the battery. The controller uses an industrial grade MCU as the main controller.
After measuring the environmental temperature, checking and discriminating the voltage, current and other parameters of the battery and solar cell components, it controls the registration and shutdown of MOSFET equipment, achieving various control and protection functions.
4. LED light source
The main objective of whether solar street lamps can be used normally is to choose the type of light source. Usually, solar lamps use low-voltage energy-saving lamps, low-voltage sodium lamps, electrodeless lamps, LED light sources, and some use high-power LED light sources.
5. Lamp pole and bracket
The street light pole device supports LED street lights.
