The car

Here’s the new solar car: Eclipse 8!

Eclipse 8, the latest solar car prototype of the ÉTS was entirely designed and built by student dedicated to this great project. Students in the Eclipse club have made their own design, both electrical and mechanical, for the entire vehicle. After having finished the foundation of the project, they stated to build it!

Eclipse 8 has the profile of a drop of water to optimize aerodynamics. The vehicule frame is made of steel in order to withstand a pressure of 5G. The frame is covered with polycarbonate for lightweight vehicule. With 391 solar cells that supply about 1200W, Eclipse 8 can run as there is sun! However it is important to mention that solar car is, above all, an electric car. Therefore, the battery consists of 450 batteries with a nominal output of more than 5000W/h.
