The Solar Car Project is a cross-school, multi-disciplinary project aimed at producing Committed And Resilient Engineers (CARE), able to handle the challenges of our increasingly competitive and demanding world. In taking on a project with a strong environmental focus, we hope to raise public awareness in renewable energy and sustainable transportation.
The SunSPEC5, built by a team of students and staff from the Singapore Polytechnic, has the following key features:
• Futuristic aerodynamic (low drag) design
• Carbon fibre composite body
• Double wrist bone suspension system
• Hydraulic braking system
• 5.0m2 of Mono-Crystalline panel
• Twin brushless DC motors
• Digital instrument display
• Average speed: 75kmph
• Top speed: 85kmph
Singapore Polytechnic is the only Polytechnic entrant in the World Solar Challenge 2017. For the students who participated in the race, it has been a tremendous learning experience as they were called out of their comfort zone to face the unknown and put on their mettle at every turn in the Australian outback.
The SunSPEC4 had participants in the Cruiser Class race some 3,000km across the breadth of Australia from Darwin to Adelaide from 18/10/2015 to 25/10/2015, without a single drop of fuel and with only one mid-point charging station.
The car operated on actual roads, at road speeds and powered only by the sun. This is the third time that SunSPEC4 is participating in the World Solar Challenge for the third time, with SunSPEC4 as its first entrant in the Cruiser Class. The car is equipped with 6 m2 of solar cells, two units of 2 kW brushless DC. motor mounted and a 15 kWh of Lithium-Ion battery bank. The car body is made of carbon fibre and the entire car is supported with double Wishbone Suspension and four wheels with low rolling resistance tyres.
The SunSPEC3 built by the team of students and staff from the Singapore Polytechnic, had participated in Australia competing in the Bridgestone World Solar Challenge from 6/10/2013 to 13/10/2013, running over 3000km from Darwin to Adelaide and powered only by the sun.
The car is equipped with 6 m2 of solar cells, two units of 1000W brushless DC motor mounted and a 5 kWh of Lithium-Ion battery bank. The car body is made of carbon fibre and the entire car is supported with double Wishbone Suspension and four wheels with low rolling resistance tyres.
SunSPEC2The project required students to design a mechanically stable structure that can support 800W solar panels, an electric motor, and electric systems such as energy storage, charge controller and control circuits. The car participated in Shell Eco-Marathon Asia 2012 and won the GOLD in the solar car category.
SunSPEC1The students made and designed the first prototype of solar car that can capture solar energy for generating electricity and driving a car. The solar car was powered by 560W solar panels and driven by a motor and battery bank. The electronic control circuits were used to control speed of car and gain maximum energy efficiency.
