We did the experiments to choose the right materials.

1. SOLAR PANEL PRE-WORK
experimental stage

2. For the first experiment we decided to test the
aluminium tins in plastic bottles with the black tube
passing through .

6. We then painted the surface black

7. The second experiment is going to be with plain
black tube in two different versions

10. One of the tubes is painted white and the other
one is left plain black

11. The third experiment is with the black tube passing
through plastic bottles

12. The different models are
filled with water to start
the measurements on
• the angle the panels
should be placed
• the temperature of
the water after a
certain period of time
• The final material
that is going to be
used .

16. 1. Black tube – plain
2. Black tube – painted
white
3. Black tube in plastic
bottles
4. Black tube passing
through aluminium
tins in plastic bottles

17. The temperature is taken at different times

18. • Start time : 8.25 am
• Initial water
temperature :
26◦C
• Ambient temperature:
30◦C at 9.30 am
40◦C at 12.50 pm
• Tube angle : 45◦

19. Testing the water after is being left in the sun
for a certain period of time

20. 1. Black tube – plain = 55 ◦C
2. Black tube – painted
white = 40 ◦C
3. Black tube in plastic
bottles = 69◦C
4. Black tube passing
through aluminium tins
in plastic bottles = 73◦C
