 There are several types of PV widely available on the market, and many more in research stages.  PV are described by how each panel's cells are constructed. There are several types of PV widely available on the market, and many more in research stages.  PV are described by how each panel's cells are constructed.

 Higher efficiency doesn't mean the panel makes more power;  it means it makes more power from a given area.  100w is 100w, but you might be able to fit a 110w panel high-efficiency panel in the same space as a regular-efficiency panel.  Higher efficiency doesn't mean the panel makes more power;  it means it makes more power from a given area.  100w is 100w, but you might be able to fit a 110w panel high-efficiency panel in the same space as a regular-efficiency panel.
