Artistimpression of a corner section of the front side of a solar panel on Rosetta. The black squares are individual solar cells covered with grounded cover glass, connected in series via (pink) interconnects in a column that wrap around to the next column near the top edge (and bottom, not shown) of the solar panel via a longer interconnect (also pink). At the start and end of each string of 91 solar cells are bus bars, marked with red (anode) and blue (cathode). The grey circle represents one of six circular Kevlar cutter/hold-down points. All surfaces coloured in pink and red are exposed positively biased conductors.
