BG ICF Solar Powered Sleeper Coaches --- On July 14, Indian Railways rolled out its first train with rooftop solar panels that power the lights, fans, and information display systems inside passenger coaches. The rooftop solar system was developed by Noida-based Jakson Engineers, under the direction of the Indian Railways Organisation for Alternate Fuels (IROAF). IROAF has developed this system with a smart MPPT inverter which optimises power generation on a moving train to cater to full load even during the night. The unique feature of Battery Bank through storage battery ensures sufficient electricity when the sunlight is not available. Solar hotel load (Lighting and Fan) system fitted on each coach is of 4.5 KWp capacity consisting of 16 Solar Panels of 300Wp each. This is adequate to power the fans and lights of the coach. The system is capable of developing up to 20 kWh per day (average) throughout the year. Surplus power generated during peak hours is stored in a 120 AH battery system.
