Through the continuous development of the times, many places have begun to use Solar led street light(CLASSIC). Solar LED street light not only bring us the light of the night, but also bring the economic benefits of energy saving. Let us now talk about how solar LED street light can save energy:
How to store solar panels?
The main material of solar panels is silicon. When a solar panel is illuminated by light, it converts light energy into electrical energy, which allows electrical energy to flow from one side to the other. The problem is that the panel reflects sunlight, so the smart person invented something: a film that avoids light reflection, which is placed on the panel to make it purple. The tilt angle of the panel also affects the lighting effect.
How does light energy translate into electricity?
During the day, the photovoltaic module absorbs light, converts it into electrical energy and stores it in a solar cell, then releases it at night. Usually, on a sunny day, it takes only 4 hours to fill the electrical energy. Each time it is full of electricity, it can last for more than 5 days, and the weather is rainy for 4 days. It should be noted here that the controller can set the light control, time and space so that the intensity of the placement point can be controlled.
First of all, when installing a solar LED street light, it is not necessary to embed the cable in advance, and it is not necessary to dig the road surface, saving most of the manpower and material resources. In terms of power consumption, the general illumination time of street lamps is about 7 hours. About 3 degrees, 400 yuan per year of electricity demand, if a city is calculated according to 400 street lights, it can spend nearly 160,000 per year, using solar LED street lights can be completely saved.
According to reports, the country adds 50 million outdoor lighting every year. If solar LED street lights account for a thousandth, the country can save hundreds of millions of kilowatt-hours of electricity per year, equivalent to sending a 100,000-kilowatt power station to the country.
