View: 39903/24/2020  

Why is 20W solar street light so popular?

As we all know, a lot of energy in the world is nonrenewable, and the supply of energy is relatively tight. Many countries even want to fight for nonrenewable energy even if they want to start a war. At the same time, they are also vigorously developing the application of renewable energy, among which solar energy is one of the inexhaustible green energy. No matter developed countries such as Germany, the United States, etc. vigorously promote the use of solar energy, solar lighting and power generation. Many developing countries, such as South Africa and Brazil, are also actively responding to the call to promote green new energy.

Solar energy has many advantages: safety, no noise, no pollution, solar power generation does not need energy problems, no regional restrictions, no fuel consumption, no mechanical rotating parts, low failure rate, simple maintenance, short construction period, random size, easy to combine with buildings, etc. All these advantages are inferior to coal power generation, which not only saves resources but also protects the environment.

What are the advantages of installing 20W solar street lights?

Compared with the cost of a solar street light, it has a long-term benefit. Because the line is simple, there is no maintenance cost and no expensive electricity cost. 6-7 years to recover the cost, after 3-4 years to save more than 1 million electricity and maintenance costs.

In the later period of maintenance, the electric cost of circuit light is high and the circuit is complex. It needs long-term and uninterrupted maintenance of the circuit. The danger is also very high. It needs a lot of maintenance costs. Once there is a problem, it will cause a lot of consumption.

Compared with the life of solar lights, the life of solar lights is much longer than that of ordinary electric lights, For example, the service life of the main components of the solar light - solar cell module is 25 years; the average service life of the low-pressure sodium light is 18000 hours; the average service life of the low-pressure high-efficiency three primary color energy-saving light is 6000 hours; the average service life of the ultra-bright LED is more than 50000 hours; the service life of the special solar energy storage pool is 2-5 years below 38ah; the service life of the 38-150ah is 3-7 years.
