Why is the solar street light market so hot? How much do you know?

In the past two years, photovoltaic products have been trendy. How much do you know about solar streetlights? Why is the market so hot?

I. Solar streetlights have brought great convenience to human life

  1. Street lights are generally replaced with solar street lights to build cities better. Solar streetlights are reasonably priced. The traditional street lights used before had complex installation procedures, such as laying electrical circuits, and consumed a lot of electricity. They also required large wattage lamp heads, which not only made the lighting dim but also hindered the illumination of the city.
  2. Solar street lights, on the other hand, have relatively low prices, are energy-saving and environmentally friendly, and have more straightforward installation procedures than traditional ones. They do not require complex electrical circuitry. The price of solar street lights consists of four main parts: LED lamps for street lights, lamp posts, solar panels, and solar street light controllers.
  3. Saving resources has become a global concern, so solar energy has been invented to bring great convenience to human life. Moreover, China has relatively high solar radiation and abundant solar energy. The prices of solar streetlights vary. They range from around two hundred yuan to one thousand yuan. Compared to traditional street lights, they are much cheaper. The reason for the inconsistent prices of street lights is not only due to different materials but also different brand choices. For consumers, the brand is also a guarantee of quality.

Most solar street lights can illuminate for eight to nine hours when fully charged, so you can refer to this when choosing and evaluating the quality of solar street lights. When choosing street lights, you must consider the installation section. Different sections and environments require different specifications. For example, the width of rural roads is less than ten meters, mostly between four to six meters, so the wattage of the selected lamp head should be able to illuminate such a width of the road surface.

  1. Explanation of the working principle of solar street lights: During the day, under the control of the intelligent controller, the solar panel of the solar street light absorbs solar energy and converts it into electrical energy. During the day, the solar panel charges the lithium battery. At night, the lithium battery gives the LED light source power, realizing the lighting function. The DC controller can ensure that the lithium battery is not damaged due to overcharging or over-discharging. It also has functions such as PIR human body induction, light control, time control, temperature compensation, lightning protection, and reverse polarity protection.

II. Working Principle of Solar Street Lights

  1. The working principle of solar streetlights is to convert solar energy into electrical energy to achieve lighting. The top of the street light is equipped with solar panels, also known as photovoltaic modules. During the day, these photovoltaic modules made of polycrystalline silicon convert solar energy into electrical energy and store it in the battery so that the solar street lights can absorb solar energy and convert it into electrical energy under the control of the intelligent controller. During the day, the solar battery components charge the battery. In the evening, the controller controls the delivery of electricity to the light source to provide illumination at night. At night, the battery pack provides power to the LED light source, realizing the lighting function.
  2. Solar streetlights generate electricity through solar energy, so there is no need for cables, and there will be no leakage or other accidents. The DC controller can ensure that the battery pack is not damaged due to overcharging or over-discharging. It also has functions such as light control, time control, temperature compensation, lightning protection, and reverse polarity protection. There is no need to lay cables, no need for an AC power supply, and no electricity cost.
  3. Customers have recognized and vigorously promoted the low-carbon, environmentally friendly, safe, and reliable advantages of solar street lights. Therefore, they can be widely used in urban primary and secondary roads, communities, factories, tourist attractions, parking lots, and other places.

III. Advantages of Solar Street Lights

1. Abundant Energy

Solar streetlights use solar photovoltaic cells to provide electricity. As a green and environmentally friendly new energy source, solar energy is "inexhaustible and inexhaustible." Making full use of solar energy resources has a positive significance for alleviating the shortage of conventional energy sources.

2. Easy and Convenient Installation

Solar streetlights are easy to install and convenient. There is no need for extensive construction of laying cables like ordinary street lights. Only a base needs to be fixed, and all the lines and control parts are placed in the lamp holder to form a whole.

3. Low Maintenance Cost

Solar streetlights are powered by solar energy. Apart from the small amount of electricity generated by converting to the mains power supply on rainy days, the operating cost is almost zero. The entire system operates automatically without human intervention, with almost no maintenance costs.

The service life of solar streetlights also depends on the necessary maintenance during regular times. During the initial installation, strict adherence to construction standards and reasonable configuration should be followed to increase the battery pack's capacity, thereby extending the service life of solar streetlights.
