If you are walking on any streets in big cities or driving on the freeway, you are likely to see street lights. These street lights can help you navigate when walking, driving or even commuting. However, if you are walking on any streets in some remote rural areas, you are likely to see solar panel street light. So what are the differences between street lights and solar panel street light?

What is solar panel street light?

Solar panel street light is powered by crystalline silicon solar cells, maintenance-free batteries store electrical energy, ultra-bright LED lamps are used as light sources, and are controlled by an intelligent charge and discharge controller to replace traditional street lights. No need to lay cables, no AC power supply, no electricity bill, DC power supply and photosensitive control. Solar panel street light can be widely used in urban main and secondary arterial roads, communities, factories, tourist attractions, parking lots and other places.

The solar panel street light system can guarantee normal work for more than 8-15 days in rainy weather! Its system is composed of several parts (including bracket), LED lamp holder, solar lamp controller, battery (including battery incubator) and light pole.


  1. Energy saving: Solar energy is used to provide electric energy, which is inexhaustible and inexhaustible.
  2. Environmental protection: no pollution, no noise, no radiation.
  3. Safety: No accidents such as electric shock or fire.
  4. Convenience: Simple installation, no need to wire or “break the belly” for construction, and there is no concern about power cuts.
  5. Long lifespan: The solar panel street light has high technology content, the control system and accessories are international brands, intelligent design, and reliable quality.
  6. High grade: high-tech , green energy, the user unit attaches importance to technology, green image improvement, and upgrading.
  7. Low investment: a one-time investment is equivalent to AC power (the AC power investment is combined from the transformation, power input, control box, cable, engineering, etc.), one-time investment, long-term use.

Working Principle

During the day, solar panel street light are under the control of the intelligent controller, the solar panels absorb sun light and convert it into electrical energy through the irradiation of the sun. The light source is powered to realize the lighting function. 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.

Differences between solar panel street light and LED street lights

Installation comparison

When installing solar panel street light, there is no need to install complicated circuits, just make a cement base and a battery pit, and fix it with galvanized bolts.

Street lights need complicated operating procedures in the construction. First of all, it is necessary to install cables, dig trenches and pipes, thread the pipes, and backfill a large amount of civil construction, which consumes a lot of manpower, material and financial resources. Finally, debugging is required. Once a problem occurs, it will cause a lot of consumption.

Cost comparison 

Solar panel street light has a one-time investment and long-term benefits. Because of the simple wiring, no maintenance costs or expensive electricity bills are incurred. The cost will be recovered in 6-7 years, and more than 1 million electricity and maintenance costs will be saved in the next 3-4 years.

Street lights have high electricity costs and complex lines, requiring long-term uninterrupted line maintenance. Especially in the case of unstable voltage, it is inevitable that the sodium lamp is fragile, and with the extension of the age, the line aging and maintenance costs increase year by year.

Safe comparison

Because solar panel street light use 12-24V low voltage, stable voltage, reliable operation, there are no hidden safety hazards, and they are ideal products for ecological communities and road administration departments.

There are many hidden dangers in street lamp safety. People’s living environment is constantly changing. Road reconstruction, landscape engineering construction, abnormal power supply, and cross construction of water and gas pipelines bring many hidden dangers to human being.

Environmental comparison

Solar panel street light can add new selling points to the development and promotion of high-level ecological communities; solar panel street light can continuously reduce property management costs and reduce the cost of public share of owners. In summary, the inherent characteristics of solar panel street light, such as no hidden dangers, energy saving, no consumption, green environmental protection, easy installation, automatic control and maintenance-free, will directly bring obvious advantages for real estate sales and municipal engineering construction.

Lifespan comparison

The lifespan of solar panel street light is much longer than that of ordinary street lights. For example, the main components of solar panel street light-the service life of solar cell components is 25 years; the average lifespan of low-pressure sodium lamps is 18,000 hours, the average life span of super bright LED is more than 50,000 hours; the life span of solar battery is 2-5 years below 38AH; 3-7 years from 38-150AH. The initial investment of ordinary street light is much higher than the initial investment of solar panel street light.


In a word, the portable and environment-friendly characteristics of solar panel street light can make it a full substitute for ordinary street lamp, and it may also be a good choice for remote areas that cannot be connected to the power grid.
