Solar Street Lights: Sustainable Lighting:

The solar street lighting system is similar to a small world of accurate collaboration. The lamp acts as the central output part for lighting, and the light source is responsible for changing electrical energy into light energy—such as fluorescent lamps, sodium lamps, metal halide lamps, and LED light sources. Fluorescent lamps have a luminous efficiency of more than 80Lm/W and can last up to 8,000-10,000 hours; high-pressure sodium lamps have a luminous efficiency of about 120Lm/W and a service life of up to 24,000 hours; LED light sources have become the main choice for solar street lamps because of their high brightness, long lifespan, and low energy use. Optical parts control the direction and spread angle of light, mechanical parts make sure the lamp is stable and durable, and electrical parts work together with the light source to keep it running steadily.​
The solar panel serves as the system’s "energy collector," made up of solar cells connected in series and parallel, sealed with toughened glass, EVA, and TPT, and framed with an aluminum alloy. Like a hardworking "little sun," it turns solar radiation into electricity, resists wind and hail, and is easy to set up. The battery acts as an "energy storage," saving electrical energy when there is plenty of light and letting it out when lighting is needed, making sure the light source has a steady power supply at night. Acting as the system’s "intelligent brain," the solar controller provides the best charging current and voltage to the battery, stops overcharging and deep discharging, and makes the battery last longer. Poles work closely with the base: the base holds power cables to support the street lights and keeps the lampposts firmly in place to keep the whole system upright.​
During the day, under the guidance of the intelligent controller, solar panels take in solar energy, turn it into electricity, and charge the battery pack. At night, the battery pack releases electrical energy to power the light source, allowing it to light up—the whole process is automatic and needs very little manual work.​
The development of solar street lights has a long history. In 1900, inventor Clarence Kemp got a patent for the design of the first solar street lamp, which started its story. In the 1960s, photovoltaic-powered navigation devices and lighting appeared on streets, and solar lighting was officially set up. In 1973, countries around the world actively did research on ground-based uses of solar cells, with related projects increasing a lot. In the 1990s, governments all over the world actively promoted clean energy, leading to a fast increase in the use of solar street lights in civilian, commercial, and industrial areas. Today, with the progress of LED and new battery technologies, solar street lights are popular in street lighting systems because they are highly energy-efficient, have a long service life, and need little maintenance. By 2022, their market size had reached $4.56 billion, and the Asia-Pacific region had become the largest market.​
Solar street lights can be divided in many ways. By energy source, they directly use solar energy—a clean energy; by power supply mode, they are self-contained and do not rely on the traditional power grid; by application, they are widely used in street lighting, park decoration, industrial construction, military places, airports, parking lots, and other situations; by lamp head design, there are many different shapes.​
Their advantages are obvious. In terms of environmental protection and energy efficiency, they use solar power to achieve zero carbon emissions, need no fossil fuel, reduce pollutant releases, and effectively reduce the power grid load—especially suitable for remote areas or regions with poor grid coverage. Installation and maintenance costs are low: independent photovoltaic panel power supply means no need for wiring, which greatly reduces construction difficulty and expenses. LED light sources have a long lifespan of 5,000-100,000 hours, while photovoltaic panels and battery packs have a design life of 5-8 years and need little maintenance. They are highly flexible and adaptable, can work off-grid, and are suitable for mountainous regions, islands, temporary road construction lighting, and other scenarios. They also have intelligent control functions like light sensing and time control, which can automatically adjust brightness to fit different environments. In terms of policy and economics, many countries provide subsidies for renewable energy projects. Long-term operating costs are lower than those of traditional street lights, making them very economical.
