The Hands-on training on Solar Study Lamp Assembly is a part of the Gandhi Global Solar Yatra (GGSY), initiated by Prof. Chetan Singh Solanki, Department of Energy Science and Engineering, IIT Bombay. As a part of this yatra, a Students Solar Ambassador Workshop is organized on the 2nd October 2019, marking the 150th Birth Anniversary of Mahatma Gandhi. Under this workshop, more than 1 Million Students will assemble their own solar study lamps across the globe and will pledge to Non-Violence towards Environment.

‘Solar Study Lamp’ is a lighting device consisting of a solar PV module, battery, LED, and electronics. Battery, LED, and electronics are placed in a plastic housing.The look of the lamp is similar to a table lamp wherein the lamp base is connected to the LED via flexible gooseneck. The solar lamp uses 1 Watt LED as the light source and houses 3.2 Volt, 2000 mAh rechargeable Lithium Ferrous Phosphate (LiFePO4) battery to store the power. A 2.5 Watt Solar Panel charges the lamp during daytime. The lamp is designed to provide 5-6 hours of study light every day throughout the year.

This workshop is expected to be taking place at 10,000-15,000 locations. Till date, 101 countries have registered to be a part of this mega-global event. This course has been designed for Master Trainers. They will be able to understand climate change, energy sustainability and will learn to assemble a solar study lamp. The course also lays protocols for conducting the Students Solar Ambassador Workshop.

A similar workshop was organized last year also, wherein over 1.32 lakh students participated in this mega-global event, of which 5,000 students came to IIT Bombay campus, which was also a Guinness World Record event.
