With its unique advantages of energy saving, environmental protection and easy installation, the new rural solar street lights have quietly flown into the streets and alleys of the city. As a new energy-saving measure, how much can solar street lights contribute to energy saving?

1 Energy-saving economy

First of all, each solar street light is a relatively independent system. During installation and construction, there is no need to pre-bury cables or dig the road surface, which saves a considerable amount of manpower, material resources and installation costs; in terms of power consumption, an ordinary street light is on for about 6 hours a day, and the power consumption is about 2 degrees, which costs more than 300 yuan a year. If a city has 300 street lights, it will cost nearly 100,000 yuan a year. If solar street lights are used, the whole province will be saved.

According to reports, 50 million outdoor lighting lamps are added every year in the country. If solar lamps can account for one thousandth of them, it can save hundreds of millions of degrees of electricity a year, which is equivalent to giving the country a 100,000-kilowatt power station.

2 Energy-saving principle

2.1 How do solar panels of new rural solar street light manufacturers store energy?

The main material of solar panels is silicon, and there are also some other alloys. When solar panels are exposed to light, they can convert light energy into electrical energy, allowing current to flow from one side to the other. Solar panels are designed based on this principle.

Solar panels can generally generate electricity as long as they are exposed to sunlight or light. In order to minimize light reflection and improve the photoelectric conversion rate of solar panels, a layer of anti-light reflection film is generally covered on them, making the surface of the solar panel purple. In addition, the inclination of the solar panel will also have a considerable impact on whether the solar street light can effectively lighten.

2.2 How is light energy converted into electrical energy?

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 it for lighting at night. Generally, on sunny days, under ideal light intensity, it only takes 4 hours to fully charge, and each charge can guarantee more than 5 days, and it can work normally even if it is cloudy and rainy for 3 consecutive days.

In addition, according to different requirements, the controller can design the switch of the new rural solar street light manufacturer as light control or time control, which can not only control the time of battery charging and discharging, but also the intensity of discharge.

In short, in cities with increasing energy consumption, urban electricity consumption has been overwhelmed: industrial electricity consumption and domestic electricity consumption have remained high in recent years, rising year by year, and power outages during peak hours in many cities are common. If solar street lights can be widely popularized, people don't have to worry about the impact on normal production and life.
