This "how to make a solar panel" video shows how to connect everything together including all wiring, soldering and cell layout (using tabbed solar cells). Full easy instructions. if you are using "untabbed" solar cells watch my video on "Solar Cell Tabbing". (tabbing is very easy to do). items can be bought as a kit on ebay. for about $48.00 you can get 40 solar cells, tabbing wire, bus wire, flux pen and even blocking diode. i used lead free rosin core solder from harbor freight. cost about $2.50. soldering iron is just a basic 30 watter. the third (and final) video will show how to encase/enclose the panels in either a plywood box or metal framed case. UPDATE: (11/10/2016) i just got the third and final video posted showing how to make the enclosure (or case) for the solar panel. here's the link youtu.be/B1rtLwVe2m8
