Energy saving principle of solar street lights

Through the constant development of the times, there are many local areas that have begun to use LED solar street lights. Solar street lights bring us not only the light in the night, but also the economic benefits brought by energy saving. Now let’s talk about how solar energy street lights are energy efficient:

  1. the principle of energy saving

How is solar panel stored?

The main material for solar panels is silicon. When the solar panel is illuminated by light, it can convert light energy into electrical energy, which can make electrical energy flow from one side to the other. The problem with this is that the panel reflects sunlight, so smart people invent a thing: a film that avoids light reflection, which is placed over the panel to make it purple. The tilt angle of the panel can also affect the lighting effect.


How does light energy transform into electricity?

In the daytime, photovoltaic modules absorb light, convert solar energy into electrical energy and store it in the solar light battery, and then release electricity in the evening. Generally, when it is sunny, it only takes 4 hours to fill the electric energy. Each time it can be filled with electric energy, it can last for more than 5 days, and the weather is rainy for 4 days. It should be noted here that the light control, time and space can be set by the controller, so that the intensity of the placement point can be controlled.

2. Energy saving economy

First of all, when the solar street light is installed, it is not necessary to pre-embed the cable, and it is not necessary to excavate the road surface, saving a large part of human and material resources. In terms of power consumption, the general lighting time of a street light is about 7 hours. About 3 degrees, the annual electricity demand of 400 RMB, if a city is calculated according to 400 street lights, it can cost nearly 160,000 a year, using solar street lights can be fully saved.

According to reports, the country has added 50 million new outdoor lighting every year. If solar lights can account for one-thousandth of a thousand, the country can save hundreds of millions of kWh of electricity a year, which is equivalent to sending a 100,000-kilowatt power station to the country.
