Solar Panel Build – More Power!

A new solar panel is born – More Power!

As we learned from our feedback, solar cells must all be of the same size/power capacity to hook them in series properly. In the original solar panel we had snapped our third row of cells in half to get them to fit down the remaining glass and make it easy to solder together. That essentially limits the current output of the entire panel because the full size cells are choked by the limited current that can pass through the snapped cells. So we built another panel using all complete cells. It made it take a little longer wiring the cells together since we couldn’t just run down the straight line of them all, but we found that using tabbing wire for everything worked good. If you bend or fold the tabbing wire to make 90 degree angles it made it pretty easy to solder to the next cell.
