    I'm trying to cool a heat exchange system by running a small 12v 400ma DC fan. The unit must provide enough power to run the fan for 10 hrs. If using solar cells how many cells will I need?

    Consult with your solar cell vendor to size your system.

    Are you trying to directly run from the cell or use the cell to charge a battery?
