As the main energy source of energy conservation and emissions reduction in the new century lamp, solar energy has been welcome by many consumers. As & other; Low-carbon lighting & throughout; The rise of the concept of led solar street lamps become the choice of this concept. Use energy-saving solar street light system, and for people's work and life, clean and environmental protection of green lighting. However, because the solar photovoltaic power generation system input energy extremely unstable, so configure battery system requirements are working properly. Solar street light is no exception. It is necessary to configure the battery work. First choice of battery capacity is usually follow the following principles, solar led street lamp to store as much as possible the sunlight solar energy battery components, at the same time meet the requirements of lighting at night. At the same time, they also can store up to meet the demand of continuous rainy day lighting of electricity. When using the led solar street light, must pay attention to safety problems, because it is the use of solar panels to receive solar energy, if the battery problems are likely to cause traffic accidents caused by outdoor lamps and lanterns is suddenly damaged.
