Solar panel (for electricity)

By buying the raw solar cells and making the panel yourself you can get solar electricity for cheap. If you get broken/chipped cells you can make it even cheaper.

The prototype panel on the picture is made from broken 6''x6'' mono crystaline cells. They output approximately 0.5V each for a total of 12x0.5V = 6V. That means that they will need a power converter in order to charge a standard 12V battery. We are working on an arduino based charge controller / power converter to use for this purpose.
