Hon’ble Railway Minister flags off worlds’ first DEMU passenger train with prototype solar-based hotel load system with battery backup commissioned by Jakson

  • • Solar system installed on each coach to generate 7200 kWh of energy every year
  • • To save 21,000 litres of diesel per train with 6 coaches – Cost savings of 2 lakh per coach every year for 25 years
  • • Reduce CO2 generation by 9 tonnes per coach per year

New Delhi, July 14, 2017: Hon’ble Minister of Railways, Government of India, Shri Suresh Prabhu today flagged-off the first 1600 HP Diesel Electric Multiple Unit (DEMU) coach of Indian Railways equipped with solar-powered hotel load system installed and commissioned by Jakson Engineers Limited, from the Safdarjung Railway Station in Delhi. The installed solar rooftop system will generate 7200 KW of energy per year per system which will be used for powering internal lights, fans and other electrical systems of the coach. The project will help offset carbon emissions by 9 tonnes per coach per year and also save about 21,000 litres of diesel for a solar-powered DEMU with six trailer coaches, thereby bringing cost saving of Rs 12 lakh every year.

Jakson was awarded this project by the Indian Railways Organization for Alternate Fuels (IROAF), a unit of Indian Railways that works to promote bio-diesels and other environmentally benign alternative fuels for India’s rail network. A total of 16 solar panels of 300 Wp, manufactured by Jakson at its state-of-the-art solar module manufacturing plant in Greater Noida power have been installed on the roof of the coach to generate the requisite power.

“It is not an easy task to fit solar panels on the roof of train coaches that run at speeds of 80 km per hour. Our engineering skills were put to real test during the execution of this rooftop solar project for Indian Railways. With our past experience in executing other challenging solar EPC rooftop projects, we were able to develop an innovative solution that helped us execute this project suitably” said Sundeep Gupta, Vice-Chairman & Managing Director, Jakson Engineers Limited.

“Jakson has been working closely with IROAF for the past few years and executed several solar projects for Indian Railways. We are proud to have executed another landmark project successfully for them”, said Ashish Sethi, Director, Solar Business, Jakson Engineers Limited.

This is the first instance of a diesel-run passenger train fitted with solar rooftop system with battery backup. The system is capable of developing up to 20 kWh per day throughout the year. Surplus power generated during peak hours will be stored in a 120 AH battery system. It will help in generating useful data for research for adapting the system for future rollout on all trains of Indian Railways. The solar system has been fitted with anti-theft mechanism which can withstand trains running with a speed of more than 100 km/hr.
