solarca.biz Solar Powered Airplane 2200KV brushless electric motor LiFePO4 battery 4000mAh 11.1V The standard cell specifications are the following, though the individual cells can be above or below these standards. Cell Specifications Average Power (Watts): 1.8 Wp Average Current (Amps): 3.6 Imax Average Voltage (Volts): 0.5 Vmax Thickness 0.2 mm Exact dimension: 3 inches x 6 inches, or 80 mm by 150 mm Weight: Just above 6 grams, or 0.2 oz. The front of the cells (blue side, aka Sunny side) has two thick white lines, called bus bars. They are the negative terminals of the cell. The back side, where the 6 square dots are, are positive terminals. Connect the tabbing wires from the bus bar of the first cell on one side to the three dots of on the back side of the next cell. That way you have a series connection. Repeat the process on the other side of the cells. In panel making you should connect all the tabbing wires on the front for all the cells first, then flip the cells over to solder the back side in a second step. It’s important to understand the concepts of series connection and parallel connection when stringing these solar cells together to make a solar panel. Series connection of the cells increases voltage but not amperage; parallel connection of the cells increases amperage but not voltage. Series connection is when you connect the positive terminal of a cell with the negative terminal of the next cell. Parallel connection is when you connect the positive …
