Solar Energy is now taking the world by storm. We can see this in the many advancements in technology by our Indian scientists and by the Indian Government’s proactive legislatures. In 2018, the Chennai Civic Body had launched a Rs. 140 Crore venture project which plans on changing 70000 streetlights in over 15 zones, out of which 8 zones – Thiruvottiyur, Manali, Madhavaram, Ambattur, Valasaravakkam, Alandur, Perungudi, and Sholinganallur are all going have 17000 redone post lamps with streetlights introduced. Estimates are that this project could bring a 45% lessening in electricity consumption.
The focus is now on more greener and efficient technologies like solar streetlights, which use solar panels and LEDs. But why must you change over to Solar Street Lights? We shall present you with 5 compelling arguments to switch over to Solar Streetlights in Chennai!.
Solar Street Lights
Quick, cheap, and easy to install, the poles are also powered by PV panels which provide electricity to LED lamps, with an inbuilt controller and battery.
Since solar energy is converted to electrical energy, there is no additional electricity cost. A battery can fully charge itself within 5 hours and then run for the next 12 hours. It is also weatherproof and dustproof, and rainy days aren’t a problem. They are operational for the next 5 years.
These are wireless and not connected to any electricity cables; hence there are no protruding wires and no accident threat.
There is no energy cost since energy from the sun is directly being used. Since it uses green energy, there is no carbon footprint associated. There is also less light pollution since the lens used is of a special kind that adjusts brightness levels based on battery voltage and running times, thus reducing the light pollution and increasing the backup battery time.
The LEDs in the poles are coloured to reach the desired CRI that resembles the daytime sun. Hence the visibility is better at night and similar to that provided during the day.
Conventional Street Light
These require much cable-laying and trenching required, which in turn means a large workforce and also a requirement of storage for heavy-duty batteries.
The batteries need a lot of maintenance, including timely water topping, which increases labour costs. Since they are connected to an electric supply, street maintenance with a high electricity cost is quite difficult.
Since there is much cabling involved, it is very unsafe as one can get electrocuted from the direct supply of electricity. There is also an additional threat of strangulation during the installation process. There is a possibility of a short circuit.
These are connected to power grids, which are non-renewable energy sources and hence pollute the environment as a lot of carbon dioxide is released. Conventional Sodium or Metal Halide lamps also use mercury, which is very toxic to the environment. Light exposed sideways could lead to light pollution.
The yellow lights from the halide and sodium lamps are low in Colour Rendering Index (CRI), making it difficult to see and distinguish in colours. The glare from these lights can also be a cause for accidents.
With Chennai’s perfect tropical climate and hot weather, which receives constant sun, solar streetlights are the best option for efficient, green lighting solutions. Go check out Nantech Power Systems Pvt. Ltd. for the best equipment and prices in Chennai!
