Solar energy streetlights, with its unique advantages of energy saving, environmental protection, and easy installation, have quietly flown into the streets of the city... As a new energy-saving measure, how can the solar street lights save energy?  1 Energy Saving Economy Drinking Water Meter Series,Digital Drinking Water Tester,Drinking Water Meter ,Drinking Water Tester Meter Ningbo Safewell Plumbing Co., Ltd. , https://www.safewellbrass.com
First of all, each solar street light is a relatively independent system. It does not need to bury cables and do not excavate roads during installation and construction, which saves a considerable part of manpower and material resources and installation costs. Besides, it consumes electricity, and one ordinary street lamp shines one day. The light time is about 6 hours, and the power consumption is about 2 degrees. It takes more than 300 yuan for a year. A city is calculated on 300 street lights. It costs nearly 100,000 yuan a year. It uses solar street lights to save the province. 
According to reports, 50 million new outdoor lighting lamps are added every year in the country. If solar lamps can account for one thousandth of a thousand, the country will be able to save hundreds of millions of kilowatts of electricity a year, which is equivalent to sending the country a power station of 100,000 kilowatts. 
2 Energy Saving Principles
2.1 How to store solar panels? 
The main material for solar panels is silicon, and there are some other alloys. When the solar panel is exposed to light, the light energy can be converted into electrical energy, so that the current flows from one side to the other. Solar panels are designed based on this principle. 
Solar panels can emit electricity as long as they are exposed to sunlight or light. In order to minimize the reflection of light from the solar panel and increase the photoelectric conversion efficiency, a layer of light-reflecting film is generally placed on the solar panel so that the surface of the solar panel becomes purple. In addition, the tilt of solar panels will also have a considerable impact on whether solar street lights can be effectively lit. 
2.2 How can light energy be converted into electricity? 
Solar street lights are mainly composed of four parts: photovoltaic modules, light emitting diodes, solar cells, and controllers. Photovoltaic modules absorb light during the day, convert solar energy into electrical energy and store it in solar cells, and discharge electricity when it is dark at night. Generally, when it is sunny, under the ideal light intensity, fully charged as long as 4 hours, you can guarantee more than 5 days after the completion of each charge, continuous rain and 3 days can also work normally. 
In addition, according to different requirements, the controller can design the switch of the solar street light to be light control or time control. Not only the time for charging and discharging of the battery can be controlled, but also the intensity of the discharge can be controlled. 
In short, in cities with ever-increasing energy consumption, electricity consumption in urban areas has been overwhelming: industrial electricity consumption and domestic electricity consumption have remained high in recent years, and they have been rising year after year. Power consumption in many cities has been cut even more. It is common. If solar street lights can be widely used, people do not have to worry about normal production and living.
