Solar street lights illuminate the road to new rural development

Solar street lights are gradually being put into rural areas, adding a lot of brilliance to rural life. The solar street light works by using solar power generation, battery storage, and the controller to control the charging and discharging of the battery. The controller is divided into two types: light control and time control. During the day, when the sun shines on the surface of the solar cell, the electric energy generated by the solar cell charges the battery through the controller; at night, the light gradually weakens, and the working voltage and working current of the solar cell continue to decrease. When the working voltage is lower than the controller setting When the voltage is high, the controller starts to start the load, and the solar street light lights up at this time; when the set time is reached or the ambient light is too strong, the controller automatically turns off the load and the solar battery starts to charge. This cycle continues. Beautiful solar street light The solar street light is powered by high-efficiency monocrystalline (polycrystalline) silicon solar cells, uses VRLA batteries to store electrical energy, uses high-efficiency energy-saving lighting, and adopts advanced charge-discharge and lighting control circuits, with reliable performance, high luminous efficiency, high Bright, easy to install, no need to lay cables and wires, no need for AC power and electricity costs, DC power supply, photosensitive control, safe and reliable, energy saving, economical, environmentally friendly, practical , long life (solar cells can be used for 15 to 20 years, batteries can be used for 5 to 7 years) and other advantages, is the future development direction of outdoor lighting. There are street lights in front of our house recently, or solar street lights. Yesterday morning, Sister Huang, a resident of Qianyang Village in Wucheng County, told reporters this way. Beautiful solar street lights The solar street lights mentioned by Sister Huang are one of the livelihood projects implemented by Shanghai this year. The reporter learned from Qianyang Village that the village lighting project in the village has been completed and put into use this year. A total of 50 solar street lamps have been installed with financial allocations and a small part of the village's self-raised funds. Now that the square is lit up at night, the sisters also have a place to sing and dance together. Sister Huang said with a smile. I also learned from the Finance Bureau that this year, the district has installed more than 600 solar street lights for more than a dozen villages in the district through the pilot project of awarding and subsidizing one case and one discussion and the new rural demonstration village lighting project, and all of them have been put into use. , benefiting 20,000 farmers.
