What’s solar street light?
Solar street light is a kind of street light system that uses solar energy as energy source. It is mainly composed of solar panels, controllers, batteries and LED street lamps. During the daytime, the solar panel converts the sunlight energy into electricity and stores it in the battery; at night, the electricity in the battery is supplied to the LED lamps and lanterns through the controller for lighting. This kind of street light system has the characteristics of environmental protection, energy saving, safety, economy and so on, which is the ideal choice for city lighting and road lighting. Solar panels, controllers, batteries and LED lights have a variety of combinations, and different combinations can form different types of solar street lights ( different types of street lights ), such as conventional solar street lights, integrated solar street lights and split solar street lights. In addition, whether or not to connect to the utility or other charging methods will also lead to different types of solar street lights, such as AC/DC hybrid and Solar-Wind hybrid street lights.

Why go with solar street light?
ZGSM believes that there are two main reasons for choosing solar street lights, one is the limitation of power supply in the region, and the other is the energy-saving characteristics of solar energy. Of course, it also has other advantages ( What’s the advantages and disadvantages of solar energy? ), such as safety and reliability, small impact on the environment, etc., as follows, we expand one by one to explain.
Limitation of power supply
In some remote areas, mountainous regions or rural areas, there are often difficulties in power supply. These areas are not suitable for the application of AC street light due to the remote location or imperfect infrastructure, which is difficult to be covered by the traditional power grid (or unstable power supply or no power supply at all). If solar energy is abundant in these areas, solar streetlights can rely on solar power to generate electricity and provide streetlights for use at night, which not only solves the problem of power supply, but also provides stable and reliable lighting in these areas ( Find more about solar street lighting application in these areas ).
Energy saving and environmentally friendly
Solar street lights do not rely on the grid for power supply, avoiding the problem of lighting interruption due to power outages or grid failures. The risk of electrocution from solar streetlights is much lower than that from traditional streetlights using AC power, as solar streetlights use low-voltage DC power supply. Its use of low-voltage DC power supply reduces the risk of fire due to short circuit or overload. At the same time, the charging and discharging control system of solar street lamps is usually equipped with protection functions such as over-charging, over-discharging and short-circuiting, which further improves safety.
Safe and reliable
Solar street lights do not rely on grid power, avoiding the problem of lighting interruptions caused by power outages or grid failures. Solar street light adopts low-voltage DC power supply, the risk of electrocution of solar street light is much lower than that of traditional street light using AC power. Its use of low-voltage DC power supply reduces the risk of fire due to short-circuiting or overloading. At the same time, the charging and discharging control system of solar street lights are usually equipped with protection functions such as over-charging, over-discharging and short-circuiting, which further improves safety.
Convenient Installation
The installation of solar street lights is relatively simple and quick, without the need to lay complex cables and pipelines, reducing construction difficulties and costs. The installation of one-body and two-body lamps is more flexible and can meet many application scenarios, including city streets, rural roads, remote mountain roads, car parks and squares and so on.
Different solar street lights
Standard solar street light
Standard solar street light is a lighting device that uses solar panels to absorb solar energy as energy, iron-lithium or other types of batteries as energy storage devices, and semiconductor LEDs as light sources. Its various components, solar panels, batteries, and LED lamps, are placed independently, and the controller plays the role of connecting the various components in series. ZGSM’s PV series solar street light is of this design ( For more about ZGSM PV series solar street light ). This type of traditional solar street light has many advantages such as the customized solar panel/wattage/battery or the followings ( How to check the battery capacity and solar panel capacity you need? ). Of course, it also has many disadvantages, and we have selected several important ones and listed them.
| Advantages | Disadvantages |
| Solar panel capacity and battery capacity can be customized | Relatively high price |
| With higher wattage to meet project requirement | Installation is complicated |
| Installation direction of solar panel can be adjusted | Wire connection is complicated |
All in one solar street light
Different from traditional solar street lights, the components of All-in-one solar street lights ( Click on the video to learn more about the all in one solar street lights ) are integrated together. Its solar panels, controller, battery and LED light source are all installed in a lamp housing. Limited by the size of the housing, its wattage is often small, usually 80W and below. If we expand the size of the lamp housing/panel regardless of the cost, we can upgrade it to 120W. ZGSM has a variety of all-in-one solar street lights to choose from, such as PV4, PV5 and PV7 series. Thanks to the high light efficiency ( What's light efficiency and how to improve it? ) of this type of lamp, the wattage of these three can cover most application scenarios. Below we list the advantages and disadvantages of all-in-one lamps.
| Advantages | Disadvantages |
| Easy to install | Solar panel capacity is relatively small which is not suitable for insufficient sunshine area |
| Wide applications such as urban roads, rural roads, squares, parks, villa areas | Battery capacity is relatively small which is not suitable for area with long rainy days |
| Easy for transportation (ZGSM has a complete set of certificates) | High installation requirements (solar panel direction) |
All in two solar street light
All in two solar street lights are the intermediate between traditional solar street lights ( Standard solar street lights ) and integrated solar street lights ( All in one solar street lights ). From its name we can know that it is mainly composed of two parts. According to the placement of the battery, there are two types of all-in-two solar street lights. One is that the battery, solar panel and controller are together, and the LED lamp is a separate part; the other is that the battery, LED light source and controller are together, and the solar panel is a separate part. Fortunately, ZGSM has corresponding solutions for this type of all-in-two solar street lights. The left one is all-in-two solar street lights from ZGSM ( ZGSM has PV6 and PV7 all in two solar street lighting solutions, please click to check accordingly ). Due to its special design, all-in-two often has the advantages of all-in-one and traditional solar street lights, such as easy installation, adjustable solar panels, customizable battery and panel capacity, wide application, etc.
Hybrid solar street light
In addition to integrated, all in two and traditional solar street lights, hybrid solar street lights are also a major category. The hybrid solar street light that combines solar energy and wind energy combines solar panels and wind turbines to provide energy for street lights. On sunny days, solar panels can store electricity in batteries; and during strong winds, wind turbines can provide additional power. In addition to the hybrid solar and wind energy, there is also a hybrid solar street light that combines solar energy and city electricity. This type of solar street light can use the city electricity to power the LED light source ( What's the advantages of LED light source? ) to ensure the continuity of road lighting when there is insufficient solar energy. The advantages overcome the application limitations of solar street lights, and the disadvantages are complex wiring and high costs.
