Trying to drop voltage on a solar panel is my math right?

We Answered:

The easiest way to do this and STILL have all of the available current, would be to use a 7805 THREE PIN REGULATOR. This would involve no circuitry and would leave the 15VDC available all of the time to do the other work.

The hookup is VERY easy and it will handle all of the current you have available. Pin out available ar Radio Shack as would be the regulator.

Solar Panels Project?

We Answered:

If you mean electric panels, your local Radio Shack should have some low power solar cells. http://www.radioshack.com/family/index.j… The cheapest ones are about $5 each.

If you mean heating panels, this is something you can construct on your own from cardboard boxes, foil, and saran wrap. Try http://www.solarcooking.org/ for some ideas.
