Solar street lamps require four basic functional components:
A rechargeable battery stores the power generated by energy from the sun.
2. A small solar or photovoltaic array that captures sunlight during the day and converts it into electricity. Usually, the solar array is built into the light fixture. Some separate solar lamps are designed with thin wires connected to the solar array and placed in a cool place, while the solar array itself is placed in a sunny position.
3. "Charging controller" to ensure that the battery is not overcharged in bright sunlight, as well as monitor the intensity of light in the surrounding area and control LED (light-emitting diode) lights to turn on and off.
4. LED (or series OF leds), which provide light.
