Solar street lights consist of 5 main parts:
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.Solar panel are varies from wattage
systems.
Lighting Fixture
LED is usually used as lighting source of modern solar street light, 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 lights. 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. The life cycle of the battery is very important to the lifetime of the light and the capacity of the battery
will affect the backup days of the lights. There are usually 2 types of batteries: Gel Cell Deep Cycle Battery
and Lead Acid Battery and many more.
Pole
Strong Poles are necessary to all street lights, especially to solar street lights as there are often
components mounted on the top of the pole: fixtures, panels and sometimes batteries. However, in some
newer designs, the PV panels and all electronics are integrated in the pole itself. Wind resistance is also a
factor.
Also there are some accessories, like foudation cage and battery box.
