Solar trees to light up parks in Kolkata

The Bengal Government is taking a lot of initiatives to increase the share of renewable energy to the total power requirement of the state. Among renewable energy sources, solar energy is the leading contributor.

Now, the government is going for a new concept in solar lighting – solar tree. A solar tree is a set of solar panels bunched together like a tree, connected to a central pole. This type of ‘tree’ is going to be one of the crucial elements in making Kolkata an environment-friendly city. The first is going to be set up at a park in south Kolkata, and later on, would be set up across the state.

Each day, such a tree would be able to produce 5 kiloWatt (kW) of energy. Considering also the stylish object that it is, these would lead to both the saving of both money (from less use of conventional energy) and the beautification of landscapes.

Another advantage of the solar trees is that whereas panels to produce 5 kW energy would take up a space of 500 square feet (sq ft), whereas a solar tree producing the same amount of energy would take up an area of just 9 sq ft.

Each tree would have 20 solar panels, spread out like the branches on a tree. Each panel would produce 250 watt (w) of solar energy, leading to a total of 5000 w or 5 kW. The height of each tree would be 25 to 30 feet (ft). However, to enable easy maintenance, the panels would be put up in three layers at a height of 12 feet.

Initially the trees would be east-facing, but later on they would be made to rotate so that the panels move along with the sun from east to west, in order to capture the maximum amount of energy.

Central Mechanical Engineering Research Institute has designed the solar trees. They are going to be made by a nationally licensed company.

In another related development, encouraged over the drastic 80 per cent fall in electricity bill at Deshapriya Park after the installation of solar-powered lights two years ago, Kolkata Municipal Corporation (KMC) is all set to light up Jatin Das Park and Maddox Square with solar lights. The installations were inaugurated on October 24.

According to a KMC mayor-in-council member, the target is to cover all major parks with solar lights in a year or two. This will have great impact on the environment.

কলকাতার পার্কে এ বার বসছে সৌর গাছ

এত দিন সৌরবিদ্যুৎ উৎপাদনে সোলার প্যানেল দেখা যেত। এ বার সৌর গাছ দেখা যাবে রাজ্যে। একটি বৃক্ষ থেকে প্রতিদিন ৫ কিলোওয়াট বিদ্যুৎ মিলবে। শুধু আর্থিক সাশ্রয় নয়, গ্রিন সিটি গড়ার লক্ষ্যে এ ধরনের ‘সৌর গাছ’ শহরের পরিবেশ এবং সৌন্দর্যায়নে সহায়ক হবে। মডেল হিসাবে কলকাতায় প্রথম সৌর গাছটি বসানো হবে দক্ষিণ কলকাতার একটি পার্কে। এর সাফল্য দেখে রাজ্যের অন্যত্র তা বসানোর ব্যাপারে উদ্যোগী হবে বিদ্যুৎ দফতর।

কেমন হবে সৌর গাছ?

গাছে যেমন ডালপালা থাকে, ঠিক সেই ভাবে সৌর গাছে ২০টি সোলার প্যানেল যুক্ত থাকবে। প্রতিটি প্যানেল থেকে ২৫০ ওয়াট হিসেবে মোট ৫ কিলোওয়াট বিদ্যুৎ দৈনিক উৎপাদন ক্ষমতা থাকবে গাছের। একটি সৌর গাছের উচ্চতা হবে ২৫ থেকে ৩০ ফুট। তবে প্যানেলগুলি লাগানো থাকবে মাটি থেকে ১২ ফুট উপরে তিনটি স্তরে, যাতে গাছের গোড়ায় যে কোনও কাজ করা যায়।


সৌর গাছ বসানোয় সুবিধা কী?

বিশেষজ্ঞরা জানিয়েছেন ৫ কিলোওয়াট ক্ষমতা সম্পন্ন সোলার প্যানেল বসাতে কমপক্ষে ৫০০ বর্গফুট জায়গা লাগে। কিন্তু একই ক্ষমতাসম্পন্ন একটি সৌর গাছের জন্য প্রয়োজন মাত্র ৯ বর্গফুট জায়গা। তা ছাড়া গাছের আকারের কারণে দৃষ্টিনন্দনও হয়।

প্রসঙ্গত, দুবছর আগে সৌরবিদ্যুৎ চালিত আলো লাগিয়ে ও ব্যবহার করে দেশপ্রিয় পার্কের ইলেকট্রিক বিল কমেছে ৮০ শতাংশ। কলকাতা পুরসভা যতীন দাস পার্ক ও ম্যাডক্স স্কোয়ারে লাগিয়েছে এই আলো। মেয়র পারিষদ বলেন, আগামী ২ বছরের মধ্যে কলকাতার সকল বড় পার্কে এই আলো লাগানো হবে। এর ফলে পরিবেশে ভালো প্রভাব পড়বে।

Kolkata parks to have India’s first carbon-neutral lighting

The City of Joy is poised to become the first city in the country to have its public parks illuminated by an automated carbon-neutral solar lighting system, reducing the carbon footprint and electricity bills.

The new automated solar lighting system, first installed at Deshapriya Park on a trial basis, would now be extended to 28 other parks by the Kolkata Municipal Corporation, the custodian of the parks.

The unique part in this solar lighting system is that it is battery-less and connected with the power grid. An automatic control system has been put in place and the lights will be switched on automatically after evening and switched off in the morning.

The pilot project began earlier this year with Deshapriya Park where they have installed 50 solar electric posts having 180 Watt solar panels with LED lights. Earlier the electricity bill used to be Rs 17,000, but now it has come down drastically to less than Rs 2,000. That is 90 per cent savings. With this technology parks can be made 95 per cent carbon-neutral.

Parks under consideration for the project include prominent ones like Md Ali Park, College Square, Maddox Square and Subhas Sarobar Park.

When implemented, the project would result in monthly savings of lakhs of rupees in electricity bills, KMC MMIC Debashis Kumar said.

The system would also be useful for deployment in street lighting system as well as those on highways.

Kolkata to get solar grid soon

Kolkata is set to be lit up by the sun after dusk after a successful three-month pilot project at Deshapriya Park boosted the confidence of Kolkata Municipal Corporation (KMC) authorities and plans are being made to install solar panels in street lights across the city and connect them to the main conventional power grid that runs Kolkata and its suburbs.

Clean and green power

The exercise, once complete, will reduce the dependence on electricity to a great extent and also help people breathe better quality air — with lesser amounts of the deadly carbon emissions. Above all, the initiative will help the cash-strapped KMC to save crores of rupees.

The changeover will be equivalent to planting around 600 fully grown trees within the city at one go, or stop adding nearly 7,000 kilos of carbon dioxide every hour to the air we breathe. Carbon dioxide, a green house gas, is one of the major reasons behind global warming.

Solar Pilot Project

The pilot project involved 50 solar panels — installed on street lamps at Deshapriya Park in South Kolkata three months ago. It was a first of its kind experiment in India where grid-connected street lamps were using solar panels to light up roads. All solar street lighting systems that are there in the country, including in Kolkata, are battery-operated and have no connection to the grid, unlike the new system. As far as installing solar panels in street lamps across the city is concerned, a concept note has been prepared and discussions are on..

The note has been prepared by experts of KMC, CESC and a private body, which is approved by the Union government and was awarded the Green Oscar in 2004.

The project was launched in February with funds from the Housing and Urban Development Corporation Limited. The street lights were fitted with ‘intelligent controllers’ which help the LED light to use only that much power that has been generated throughout the day or less than that. The surplus, if any, will be routed to the conventional power grid and a record of the amount of power transferred would be kept for future reference.

Alternative sources of energy

A bright sunny day in May is expected to generate 1 kilowatt of electricity. The ‘intelligent controller’ will ensure that the LED bulb uses a maximum of 1 kilowatt or less, with the extra power being sent to the grid.

On a cloudy day, when there is less sunlight, the street lamp can draw power from the grid, because it had deposited the extra power it generated to the grid on a sunny day. In other words, it will be somewhat like a bank account: You can withdraw only as much as you deposit.

Street lights in Kolkata consume around 10 MW of electricity every hour. As this power comes from the burning of coal in our thermal power plants, at least 7,000 kilos of carbon dioxide are emitted to the atmosphere every hour to light up Kolkata. If the power is shifted to solar, this can be stopped to a great extent, if not entirely.

Parks in Kolkata get a new look, courtesy KMC

This is the first time that any Chief Minister has thought about a green Kolkata, a beautiful Kolkata. As a result of the special interest shown by Chief Minister Mamata Banerjee, beautification of parks and gardens have got equal importance as any other work, like drainage, garbage clearance, roads and street lighting.

The construction and maintenance of squares, roadside gardens and median strips, and the riverfront beautification of Ganga – these comprise the biggest contributions of KMC to the city.

In 2010, Mamata Banerjee conceived the idea of Ganga Riverfront beautification. As a result, the 5 km stretch along the banks of river Ganga has been beautified, and barges, cranes and payloaders are now used during immersions of idols. For trimming trees, each Borough has been allotted a hydraulic ladder.

CCTV cameras have been installed at Elliot Park on a pilot basis for the security of the park visitors as well as for the proper maintenance of the park. 3000 CCTV cameras are going to be set up in the 144 wards across Kolkata.

Another major initiative has been the use of solar energy to light up street lamps in Deshapriya Park. This is a first in Kolkata which would reduce the usage of electricity and would also lead to reduction in carbon emission in the atmosphere.

The Goalz Project, a joint venture amongst the British Council, Kolkata Police and Kolkata Municipal Corporation, is running football training centres in Kolkata. A swimming pool of international standards and a sports training centre has been constructed at Deshbandhu Park. The work of the Department of Parks and Squares, Kolkata Municipal Corporation has made the citizens proud of their city.

Green Energy for the City Lights

In a constant effort to serve the public in the best possible way, the Kolkata Municipal Corporation takes another innovative step. As part of its multi-faceted, eco-friendly initiative, KMC has launched the country’s first ‘battery less, carbon neutral Solar Street Lights at one of the city’s favourite public place, the Deshapriya Park.

In the august presence of Sri Manish Gupta, Hon’ble MIC Power & Non-conventional Energy and other eminent personalities, Mayor Sovan Chatterjee inaugurated the path breaking project on 12th February, 2015.

Fifty solar electric posts have been set up at Deshapriya Park each of which will have an 180-watt LED based panel that is equivalent of 400 watts of sodium vapour electricity.

The solar panels will help generate electricity throughout the day and the generated power will be put into the grid. The LEDs will be lighted up with the generated power in the night. An automatic control system has been put in place and the lights will be switched on automatically after evening. It will be a carbon-neutral lighting. This project has been made with an estimated cost of Rs 40 lakh and is expected to bring down electricity bills for the Kolkata Municipal Corporation.
