SOLAR STREET LIGHTING SYSTEM

The solar street lights work on the principle of the photovoltaic cell or solar cell. The solar cell converts solar energy to the electrical energy which is stored in the battery. The solar lamp draws the current from this battery and it requires no other wiring.

WORKING OF SOLAR STREET LIGHTS

The solar street lights use solar energy, a form of the renewable energy. These days it is common to see the solar street lamps along the sides of roads. The solar lights comprise of the photovoltaic cells, which absorb the solar energy during daytime. The photovoltaic cells convert solar energy into electrical energy, which is stored in the battery. At the night time the lamp starts automatically and it consumes the electricity stored already in the battery .During the day time the battery gets recharged and the process keeps on repeating every day.

SOLAR LED LIGHTS

LED stands for light emitting diode. Led comprises of the chemical compound that gives of the light when direct current (DC) from the battery passes through it. Solar LEDs are available from number of companies in different sizes, shapes and styles. The life of LED is usually very high extending up to 50,000 hours .The LEDs require very little current hence the solar panels of smaller sizes are required for the solar lights with LED lamps .
