 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.

 Mono panels can capture about 15-20% of this visible light energy.  Poly panels capture 13-16%, and film panels capture 9%.
+===== longevity =====
+Framed panels are often warranted to make 80% of their rated output for 25+ years.
