HISTORY
01.08.2006 Registration for the
world solar challenge 2007
15.09.2006 First test with
motor / driving systems - decision for 48 V DC motor
with chain drive to keep our budget. Efficiency 87-90%.
17.10.2006 First test with
the solar cells & the module construction successfull.
Panel will have about 9 kgs of weight / 1200 W power (20% efficiency)
19.10.2006 Chassisparts to
arrive by 26.10.2006 - then the basic construction will
start.
Weight and financial budget still within our targets...
04.11.2006 Confirmation from
the WSC organisation received - Startingnumber 10
25.11.2006 Basic chassis is
constructed - installation of safety belts and main
structure for solar panel until end of december
 three wheels for 3000
km ....
22.12.2006 First Solarpanel
- basic construction finished (above see backside)
Aluminium / Carbon - 4 x 1.61 m2
31.12.2006 Steering and two
seats installed / First Solar cells successfully soldered.
99 cells on each panel will be connected in series together with 33 cells
of the fourth panel (132 cells per string). MPPT arrived...
02.01.2007 Visa and flights
for Australia confirmed - so no way back...
We will start official information and search for additional team members
in week 2.
 
21.01.2007 Testing with first
solarpanel - Panelweight 4 kgs / Aluminium basic construction
2 kgs / Power tested at 400 W/m2 = 81 Watts
28.01.2007 Brakesystem installed
  
04.02.2007 Steering completed - Start with
construction of the remaining 3 Solarplanels
09.02.2007 Further team members
recruted - team almost complete. Team members to be
announced end of February. Further researches on batteries.
16.02.2007 Christian Völlmin and
Markus Chrétien join the team - the project is on its track...!
The last solar cells to arrive in the next days.
27.03.2007 Daniel Senn joins
the team!
2nd solarpanel is in construction - solar array should be finished by End of

Alpnach.
All documentation for the organisators sent out today.
12.05.2007 Concept for
improved tires and wheels finished. All eletronics installed.
May 07.....
05.06.2007
Official press - announcement on WSC Webpage. More than 40 participants
from 21 countries.
27.06.2007 Final
motorsupport is designed and fixed. Testrun with final setup
in the comming days. Front wheels changed to 20 inch instead of 16 inch.
07.07.2007
Testrun on the airporttrack of Alpnach was sucessfull. Some data:
Max. weight: 230 kgs / Max. speed: 70 km/h / energy 2 KW/h 100 km
14.07.2007 Test
of solarpanels at 33 C outside temperature and upto 75 C panel
temperature - max. output (calculated at 25 C / 1000 W / m2 is 1200 Watts,
some bubbles in the coating hat no negative influence on the performance.
15.07.2007
Meeting with the guys from Senegal - Team. Could exchange some ideas
between "low budget" teams.
18.08.2007
Testrun for Television and newpapers / vehicle ready for the official
introduction on 29th of august and last testrun in Switzerland.
20.08.2007 Pressinformation
/ Testrun in Bottmingen - Test of solar panel
29.08.2007
Presentation of vehicle to press and friends
11.09.2007
Packing of the vehicle and all material
26.09.2007
Shipping of the transportbox to Australia
29.09.2007 The
team takes off....
20.10.2007
Scuteering and testing was passed successfully - we have got the numberplate
for our vehicle
21.10.2007
Thousands of spectators at the start in Darwin - we passed about 6 teams on
the first 50 kilometres.
22.10.2007 Due
to cloudy weather we only made an average of 300 km per day - batteries
only deliver 1000 Watt/h instead of planned 2000 Watt/h. Other teams drive with
5000 Watt/h.
23.10.2007 After
730 km at 1130 h we are forced to load the vehicle on a trailer as we did
not make an average of 50 km/h (only 45 km/h) due to the cloudy weather. As
we did not have a trailer (!) we had to develop a rack to put the vehicle on
to of our support vehicle (Ford combi).
25.10.2007 We
put our vehicle together again an restarted - after 220 km we were hit by
one of the "famous" willy willy tornados on the road and our vehicle flew off
the road at 50 km/h. Lucky the driver (Daniel) was not hurt - but the vehicle
(front wheels, body and solar panel) were quite heavily damaged. So we we had
to transport the vehicle again.
27.10.2007 We
managed to repair the vehicle and finaly pass the finishline in Adelaide with a
lot of experience collected over the passed days- as our transportbox disapeared
between Darwin and Adelaide we had to build a new one...what an adventure!
