The working principle of all in one solar street lights is to convert solar energy into electrical energy to realize illumination. On the top of the street lights are solar panels, also known as photovoltaic modules. During the day, these polysilicon photovoltaic modules convert solar energy into electrical energy and store them in batteries, so that all in one solar street lights can be controlled intelligently. Under the control of the device, the solar cell panel is irradiated by sunlight, absorbs the solar light and converts it into electrical energy, and the solar cell components charge the battery pack during the day. In the evening, power is delivered to the light source through the control of the controller to illuminate people at night. At night, the battery pack provides power to the LED light source to realize the lighting function.
Solar street lights generate electricity through solar energy, so there is no cable, and there will be no leakage and other accidents. The DC controller can ensure that the battery pack is not damaged due to overcharging or overdischarging. It also has functions such as light control, time control, temperature compensation, lightning protection, and reverse polarity protection. No need to lay cables, no AC power supply, and no electricity bills.
All in one solar street lights have a series of advantages such as low carbon, environmental protection, safety and reliability, which are recognized by the majority of customers and have been vigorously promoted. Therefore, it can be widely used in urban main and secondary roads, communities, factories, tourist attractions, parking lots and other places.
All in one solar street light components
1. Solar photovoltaic modules
Modules are generally divided into two parts: single crystal and polycrystalline. Of course, single crystal and polycrystalline are also divided into A-side and B-side. So this is why the price of the same-configured components on the market is so different. From the outside, ordinary people can’t see it. What came out of it. The function of the module is to use solar energy to convert it into electric energy that can be stored in the battery. The current conversion rate of single crystal is up to 17%, and polycrystalline is about 12%.
2. Special battery for solar energy
As the function of storing and releasing electric energy, the battery can be installed on the light pole or buried underground. The function of the battery box is to protect the battery underground. The battery will not be corroded by underground water. The working principle of the battery is to use solar energy during the day. The electrical energy converted by photovoltaic modules is stored in the body, and when the controller instructs it to discharge at night, the product quality of manufacturers with different technical capabilities is as different as the corresponding price.
3. Solar controller
The backbone and the big heart of the all in one solar street light system are visually analogous. The human heart is good and can function normally if there is no problem. If the heart has a problem or fails, other body parts will not be useful no matter how good it is. The quality of the controller directly affects the lifespan of the solar street light system, and it is best to choose a certain brand.
4. LED light source
Nowadays, the better ones on the market use flat-panel lamp caps. The light source is optional, mainly in these two accessories. The traditional LED lamp cap has a larger shell and poor heat dissipation performance. The flat-panel lamp cap is flat and looks a little higher. The lamp holder has built-in heat dissipation, and the light source is made in China, imported, and Chinese technology reasons make it generally still imported, and the price of different selected LED light sources is also different.
5. All in one solar street light pole
The light pole part is customized according to the customer's requirements for the pole shape and configuration parameters at the beginning of the design. The size and style requirements are different, and the price varies greatly.
