Solar street lights are raised light sources which are powered by photovoltaic panels generally mounted on the lighting structure. The photovoltaic panels charge a rechargeable battery, which powers a fluorescent or LED lamp during the night.
Most solar panels turn on and turn off automatically by sensing outdoor light using a light source.Solar streetlights are designed to work throughout the night. Many can stay lit for more than one night if the sun is not available for a couple of days. Older models included lamps that were not fluorescent or LED. Solar lights installed in windy regions are generally equipped with flat panels to better cope with the winds.
VG Energy Solar street light system is designed for outdoor application in un-electrified remote areas. The system is an ideal application for illumination of streets, cross roads, forest and village lighting that are not connected with power grid. It is provided with battery storage backup sufficient to operate the light for 10-11 hours daily. Unlike LPS lamps that produce a yellow-orange light, Solar street light using LED technology generate a very powerful and targeted crisp white light of excellent quality, which significantly improves color rendition and night visibility
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 street lights comprise of, which absorb the solar energy during the daytime. The photovoltaic cells convert solar energy into electrical energy, which is stored in the battery. At the nighttime, the lamp starts automatically and it consumes the electricity already stored in the battery. During the daytime, the battery gets recharged and the process keeps on repeating every day.
Solar LED lights: LED stands for the 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.
Integrated street light
Solar panel, battery and LED lamp are all-in-one and waterproof.
