This is not a 100W solar panel. With a surface area of about 250mm X 420mm it harvests sun from 0.105 meters2 That means that the panel is exposed to 100W of energy from the sun. Assuming the best effeciency possible with current solar cells, at 23% the panel can theoretically at best deliver 23 Watt. This makes it a really expensive 23Watt panel. Under testing, a maximum delivery of 18.7Watt is measured but that can vary. Really disappointing of Banggood to do this type of dishonest marketing

This panel is really about 15 watt output and should NOT be advertised as having 100 watt capability. This is fraud.
