SolarMobil Manipal

SolarMobil Manipal is the official Solar Car student team of Manipal University, Manipal. The team was founded in 2011 by a group of engineering students of Manipal Institute of Technology. SolarMobil is a student project aimed at research & development of solar powered electric vehicle.

Till date SolarMobil Manipal has developed two projects; Freyr1 - a single seater solar race car and SERVe (Solar Electric Road Vehicle), which is India's first institutional solar electric vehicle prototype.

History

Since the early 1980s, various institutions around the world have focused on the research & development of Solar Cars. Started in 2011, SolarMobil Manipal is the third Indian Solar Car Team. The SolarMobil team consists of a group of undergraduate students pursuing multiple disciplines of engineering at Manipal Institute of Technology. SolarMobil Manipal was formed with a vision of becoming a center for research & development on solar vehicles. The team is working towards developing practical solar passenger vehicle prototypes.

The project is supported and has been supported in the past by Manipal Institute of Technology, Tata Power Solar, Element14 and other technology partners.

The Team

The team comprises thirty undergraduate students - Sophomores, Juniors and Seniors from Mechanical, Electrical and Electronics, Electronics & Communication, Instrumentation & Control, Mechatronics, Industrial Production and Automobile Engineering. The team is supported by the faculty of Manipal Institute of Technology.

The team has three separate departments - Mechanical, Electrical & Management working on various aspects of the project.

Projects

The team has developed two projects till date Freyr1 and SERVe. They are currently working on a third, unnamed project.

FREYR-1

Freyr1

The debut car was named FREYR-1, a 3–wheel 1 seat race car to participate in Solar challenges across the world. The most notable features of this car were its lightweight space frame chassis, the custom-made suspension system and its ability to drive directly on solar power using a high-power-efficiency drive train.

Achievement

The team was awarded the consolation award at the Manipal University Innovation Day in 2013.
