Components :

• Solar Panel: The solar panel is one of the most important parts of solar street lights, as the solar panel will convert solar energy into electricity. There are 2 types of solar panel: mono-crystalline and poly-crystalline. Conversion rate of mono-crystalline solar panel is much higher than poly-crystalline.

• Lighting Fixture: LED is usually used as lighting source of modern solar street lamps, as the LED will provide much higher Lumens with lower energy consumption. The energy consumption of LED fixture is at least 50% lower than HPS fixture which is widely used as lighting source in Traditional street lamps. LEDs lack of warm up time also allows for use of motion detectors for additional efficiency gains.

• Rechargeable Battery: Battery will store the electricity from solar panel during the day and provide energy to the fixture during night.

• Controller: Controller is very important for solar street light. A controller will usually decide to switch on /off charging and lighting. Modern controllers are programmable so that user can decide the appropriate chance of charging, lighting and dimming.

• Pole: Strong Poles are necessary to all street lamps, especially to solar street lights as there are often components mounted on the top of the pole: fixtures, panels and sometimes batteries. However, we can also integrate the PV panels and all electronics in the pole itself.
