What varieties of solar-powered street lighting solutions are available?
Solar street lights are of three types. Read on to know what these are:
1.Split solar street light
Split solar street lights have two main parts: the solar panel and the light itself. The solar panel is usually installed separately, often on top of a pole or another location where it can catch the most sunlight. It’s connected to the light through wires. This design allows for flexibility in placing the solar panel in the best position for maximum sunlight exposure. These lights are a good choice when you want to illuminate specific areas and need the solar panel to be positioned separately for optimal energy absorption.
2.All-in-one solar street light
As the name suggests, all-in-one solar street lights integrate all components into one compact unit. The solar panel, battery, LED lights, and other electronics are all housed in a single fixture. This design makes installation simpler and more straightforward since there’s only one unit to set up.
All-in-one solar street lights are often chosen for their ease of installation and maintenance. They are convenient for locations where a streamlined and hassle-free lighting solution is preferred.
3.All-in-two solar street light
All-in-two solar street lights are a hybrid between the split and all-in-one designs. These lights separate the solar panel and the LED light but keep them closely connected. The solar panel is usually connected to the light through a cable, providing some flexibility in positioning while maintaining a more compact setup than split solar lights.
This design offers a balance between the installation flexibility of split lights and the integrated simplicity of all-in-one lights.
Each type of solar street light has its advantages, and the choice depends on factors such as installation preferences, specific lighting needs, and environmental conditions in the area where they will be used.
Advantages of solar street lights:
Solar street lights offer a multitude of benefits that make them an increasingly popular choice for outdoor lighting solutions. One significant advantage lies in their environmental friendliness.
