Toolbox 2

Hi everybody,

before our holidays begin, I send you a last post about the wind turbine.
Fisrt, We 've painted the wood so that it resists the bad weather.



Our technician helped us a lot by puting it on a pole with a ball bearing for the rotation. He took the ball bearing from an old wheel of trash can!




Then we decided to fix the datalogger on the turbine to avoid the wires to roll around the pole. This way, the electric contact shall always be maintained. You can see the metal piece on wich we will fix the datalogger on the next two photos. We hope the weight of the datalogger won't be a problem ...
And we should install the wind turbine on the roof after our holidays, at the beginning of March.

I hope this can help you with your own installation,
ciao,
Emilie

Orientation of the solar Panel

Hi friends,

The orientation of the panel is very important for the project:the best orientation for all the school is not the same orientation.
It depends from the latitude and the season.

Here an interesting site with a lot of informations about the solution of the problem.
Please have a look and then we can decide the best orientation. our latitude is 45°N
