Street lights have always been an integral part of road safety. Not only in terms of preventing accidents but also for preventing cases like theft, robbery and other such big crimes that generally search for dark spots to take place. But in India, most of the times and at most of the places these street lights don’t work reason being they are expensive, conventional and requires efficient utilization of power. But the inefficient and unreliable supply of power continues to hamper the effective working of street lighting.
Electricity being non-renewable source of energy will continue to vanish from the earth, so it becomes our moral responsibility to conserve electricity and to get one step closer to it technology has invented products using solar energy replacing electricity. Solar street light is one such invention of technology and sun being the most reliable source of energy assures smooth functioning of street lights in India. Solar street lights store energy from the sun during daytime and that energy is utilized to lighten street lights at night.
There are a number of Solar street light manufacturers, and all of them use almost same kind of technology to manufacture the same. Their system design consists of Solar Panels, LED Lights, Rechargeable battery, Controller, Pole, interconnecting cables.
Solar panel, also known as solar photovoltaic cells is one of the most important components that is being used in solar street lights. Polycrystalline and monocrystalline are two types of solar photovoltaic cells being used. Solar panels are used to convert stored solar energy into electricity, which in turn is used to run numerous applications.
Led Lights is another component used by the solar street light manufacturer, it provides bright light consuming less energy. LED Fixture uses very less energy as compared to HPS fixture, which is generally used in traditional street lights. LED Lights are durable, eco- friendly and best part is that it doesn’t emit UV rays.
The rechargeable battery is an electric battery that helps to store electricity that has been converted by solar panels during the daytime. While using a rechargeable battery, Solar street light System and solution in India look for capacity and lifetime of the battery, as it affects the backup power of street light.
The controller is one of the main element being used by solar street light manufacturers as it decides when to switch on and switch off the lights and charging. They also decide the brightness of the light.Pole and interconnecting cables are part of fixtures that are being used by solar street light manufacturers in India. The battery box, LED Lights and solar panel are placed on the top of the pole and consume 7.2 watts of input power.
