Eilat – Ludwigshafen – Ljubljana , December 2014
Team: SOLAR CARS RENAISSANCE

Introduction
Photovoltaics developing alternative
Work towards energy autarchy of the cities
Clean solar energy fuel for vehicles
How solar cells work?
Two different types of semi-conductor layers (sillicon)
Two layers together => P-N junction
Difference in electrons causes current
Brief history
The first solar car was invented 60 years ago
In 1981 Tholstrup built a solar powered race car in which he crossed Australia
Breakthroughs through the yearsFirst solar car
Brief history
New cars been developed…
World Solar Challenge invented by Tholstrup, an australian solar car inventor
Modern racing solar car
Advantages of solar cars
NO AIR OR NOSIE POLLUTION
The purchaser does not have to purchase USUAL fuel
Cheaper and less regular
maintenance service than
conventional cars (Blue, 2014)
Current problems
People are not driving solar cars now because:
None commonly available in market
Too small
Design is not appealing to the consumer
Not reliable, fuel problems
Dream cars?
Nowadays solar cars
Would you buy one like this?
The car solution
4 m2 of semi-flexible solar panels8h recharging from the sun
Grid battery charging:4 h completely,20 min for 80% full battery
• 1000 kg full
• 150 km range
• 30000 $
• 4 seater
• 120 km/h top speed
• 80 kW motor (Bosch)
Comparison
Drag coefficient 0.2
115 kW
Drag coefficient: 0.28
Electric motor Petrol motor
80 kW
The city solution
Picture 6:• State’s investment into solar panels near parking lots
• Recharging cars from the grid(plug in), for a price
Conclusion These solutions would slowly convince the population to change their way of transport.
Change the way of thinking
Less consumptionate society
