electric circuit for the solarpanel

Hello everybody,
after our VERY NICE meeting in Badia, we had to solve the problem of measuring the power produced by the solar panel (which can maximal be 20 W). Its tension can rise until 20 V and our datalogger Xplorer GLX cannot measure beyond 10V.
Marie finally bought two resistances (10 Ohms, 25 Watts) that we put in series like this :

This way, V stays always under 10V and the currentintensity stays under 1 A, so our GLX stay happy !!!
And we get P by mulitplying 2 x volts x amperes.
If you want to see the result ... http://www.youtube.com/watch?v=0M65fpljiXk
à bientôt,

Emilie

Meeting in Badia 18th - 22nd may 2011

A BIG THANKS TO ALL GUESTS THAT MADE THE MEETING VERY..... SOLAR

Accident on the way (2)

The broken "airplan" is now adjusted!!!

we changed some parts of the generator and we put it on the top of Totem. we did'nt make electrical connection yet. Here some photos of the results.

Logo for Core Europe

Hi all,
I love this idea for a logo - If everyone sends me a picture of the energy site they will be visiting I will try and create something similar.

That is if you like it?????

Toolbox 3

The system of collect and measure the solar energy is ready. We put a panel on the wall of the  lab inside the school and in the next two photo we are showing what we can do. The energy from the solar panel (on the top with an angle of 17°1) comes from top right of the panel, nothing is coming from the wind (top left of the panel) because  the "airplane" is still brocken. The system seems run without problems.

Photo N.1 -  Charging the Battery (left side of the Panel)
You can see from the top: a) the solar Regulator; b) the Inverter and c) the Battery

Photo N.2 -  Measuring Energy (right side of the Panel)
You can see from the top: a) measure of Volt; b) measure of ampère c) lamps (6W - 12V each)

Accident on the way

Hi,
We left the Totem on the roof for some days to check tha stability of it. Unfortunately Sunday a little wind made some bad effects on the system.We'll adjust it soos (I hope). No problem for solar panel.

Photo one: a general vision; you can see the weather station, the panel and the "airplan"

Phototwo: the result

Schedule for the measures (2)

Hi there, in this short video I'm trying to show you what we are doing; we hope to finish the job next week; we have not solve the problem of data, but a step by step....
