Solar Public Lighting Brings "Sunlight" To Night To Illuminate The Road

      Nowadays, solar energy has been recognized as a clean and green energy, and it is gradually applied to people's livelihood for the benefit of mankind. Among them,solar public lighting is one of the ways of solar energy application.

       Solar public lighting system generally consists of solar panels, controllers, batteries, lamp heads, lamp poles, cables and other parts.

      Solar public lighting systems rely on sunlight to illuminate solar panels during the day to generate electricity, and deliver the generated electricity to a battery for storage. At night, when the light intensity drops to a certain level or reaches a certain time, it is controlled by the controller to make the battery discharge the light source electrical appliances. When the light level rises to a certain level or a certain time, the power consumption is automatically turned off. It has been widely recognized by the society for its advantages such as no need to lay cables, no consumption of conventional energy, energy saving and environmental protection, and easy installation.

       Previously, in the western region with insufficient power resources as an example, most rural power users were far away from the power grid, and residents lived scattered. The construction cost of high-voltage power transmission was 100,000-130,000 yuan per kilometer, resulting in high cost of power supply lines. The power supply of the power grid is mainly used to meet the needs of rural residents' life and production. The most important ones are lighting, small appliances, and agricultural irrigation. As for the public facilities such as road lighting, with the maturity of solar photovoltaic power generation technology, solar photovoltaic power generation in many places is regarded as the best way to solve the problem of rural power generation.
