Cells:
The standard cell specifications are the following, though the individual cells can be above or below these standards.
Cell Specifications:
Average Power (Watts): 1.75 Wp
Average Current (Amps): 3.5 Imax
Average Voltage (Volts): 0.5 Vmax
Thickness 200 μm = 0.2 mm
Exact dimension: 3 inches x 3 inches,
Weight: Just above 6 grams, or 0.2 oz.
Tabbing wires: $22 value - 110 feet of tabbing wires that Evergreen Solar uses to connect the solar cells. Cut them into 6 inch sections to solder onto the bus bars on the cells. You will get slightly more than 110 feet, but 108 feet is what you need to tab 108 cells.
Bus wires: $5.5 value - 11 feet of bus wires. Use them to connect them between the series and connect the tabbing wires ends to the junction box at the back of the panel.
Flux: $7-$9 value - an easy-to-use flux pen that dispenses flux onto the bus bar or your tabbing wires without leaving a mess. It's used to aid soldering and bonding of the wires to the cells. A must have item.
Solder: $7-$9 value - a tube of solder to help you solder the tabbing wires and the bus wires together, or whenever you need extra solder.
