Hi all I hope I post to the relevant forum .

I want to use ARDUINO in the SOLAR ENERGY field .

My question is : What is the general direction of using ARDUINO or other micros in the SOLAR ENERGY field ?

Thanks Elico

use it with care as higher voltages can damage your arduino. 2) an arduino is not made for outside use unless in an appropiate casing.

What do you want to do? - monitor energy - rotate solarcells to optimize output - control a car wiper to keep the solar cell clean?

PLease tell us more about the goal of your project.

Ummm... What do you want to do????

You could certainly build a solar enegry system, complete with a battery charger and a DC-to-AC converter, and even with automatic switching between solar & the power-company. and, that could be done without a microcontroller...

If you wanted to make a sun-tracking mirror, that would be a good Arduino project because you need something to "make decisions"... Do I need to move? What direction should I move? How much should I move? Have I moved far enough? Have I moved too far?

When I think about what makes compters (and microcontrollers, etc.) and programming useful, I think of the following things:

1. Doing things over-and-over in a loop. For example, making the same calculation in hundreds or thousands of cells in a spreadsheet.

2. Making calculations.

3. Making "logical" decisions. If the sun is out, and it's the weekend, turn-on the solar swimming pool heater. If it's the weekend, and the sun is behind a cloud, turn-on the gas pool heater. (But, one simple decision like that could be done without a "brain chip", although knowing what time it is and what day it is can be somewhat complicated, and it's easy for a computer.)

4. Storing data.

Thanks Elico

I did a project that: 1-Make a calculation of total power of 4 x 180 watt cell then is exported to a excel 2-swicht the cell form all in parallel to 2 in series in parallel with 2 in series when the sun is not enough for increment the output power

I would use Arduino in solar energy field: 1) to manage charging process of batteries 2) to track the Sun 3) to monitor and gather data 4) communicate with PC (upload data)

Thanks to all Elico

So what will be your project?
