Most of the street lights we see on the road use solar energy. Solar street lights are powered by sunlight. During the day, the sunlight is used to charge the battery of the battery panel, and the battery is used for the light source at night. The whole process is energy-saving, pollution-free and stable in operation, and does not require manual operation. Principles of
solar street light - structure 1. Solar panels Solar panels are the core part of
solar street lights and the most valuable part of solar street lights. Its function is to convert the solar radiation into electrical energy, or send it to the battery for storage. Solar cells mainly use monocrystalline silicon as the material. The P-N junction in a similar diode is made of single crystal silicon. The working principle is similar to that of diodes. It's just that in diodes, it is the external electric field that drives the movement of P-N junction holes and electrons, while in solar cells, it is solar photons and light radiant heat that drive and influence the movement of P-N junction holes and electrons. Also known as the principle of photovoltaic effect. At present, the power of photoelectric conversion is about 13%-15% of monocrystalline silicon and 11%-13% of polycrystalline silicon. The latest technology now also includes photovoltaic thin-film cells. 2. Solar controller The most important part of the solar lighting system is the controller, and 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. By measuring the ambient temperature, checking and judging parameters such as the voltage and current of the battery and solar cell components, it controls the registration and shutdown of the MOSFET device to achieve various control and protection functions.
solar lights solar led flood lights suppliers, as the name suggests, find extensive use in solar led flood lights suppliers institutions. Since solar led flood lights suppliers has become much dependent on technology in today's world, there is wide use of such solar lights.
