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).
Soldering is an excellent method for prototyping, low to moderate volume production, and devices that require the PV cell to be externally mounted away from the PCB. Leads can be soldered directly to the top of the foil bus tape through the protective laminate, or contacts can be exposed on the backside of the module.

The number of broken cells will be more if you handle more number of cells. It is important to carry out soldering with utmost care. This is because un-tabbed cells are required to be soldered across a cell. In the case of un-tabbed cells, the work involved is almost double and, therefore, the chances are that you will break some cells.
