Solar Landscape Light Introduction
The solar landscape light manufacturer uses high-efficiency monocrystalline silicon solar cell modules. It can convert sunlight energy into electrical energy during the day and store it in the battery. It automatically lights up after dark at night. Sights, resorts, golf courses, corporate factory greenery landscaping, residential area greenery lighting, various green belts and other embellishments and lighting. Adopting LED light-emitting diode design, it has the advantages of high brightness, easy installation, reliable work, no cable laying, no consumption of conventional energy, long service life, etc. These make solar battery-powered landscape lights show many unprecedented advantages.

System composition, control principle and circuit principle of solar landscape light
System composition of solar landscape light
Solar landscape light is an independent power generation system. It can independently convert solar energy into electrical energy, and can convert electrical energy into thermal energy for lighting and decoration, without the need to erect or embed a transmission line for transmission. Its simple structure is mainly composed of solar panel, charge and discharge controller, battery, lighting circuit and lamp pole.

Design of Charge and Discharge Controller for Solar Landscape Light
As the interface circuit of photovoltaic cells and lead-acid batteries, the charging controller generally hopes to work at the maximum power point to achieve higher efficiency, but at the same time as the maximum power point tracking (MPPT), the battery charging needs to be considered control. At present, the main circuit topology commonly used mainly includes a buck converter, a boost converter, a Cuk converter, and the like. In general, the output voltage of photovoltaic cells fluctuates greatly, and Buck converters or Boost converters can only perform buck or boost conversion. Due to this, photovoltaic cells cannot fully operate at the maximum power point in a wide range.
