What he doesn’t attempt to make clear is, why do two different types of panels (differing in substrates and size) that are rated at the same wattage (i.e. Power) might produce results that are different than their manufacturer’s 100w ratings??

The 100 watt rating of the panels is "Ideal conditions"
The roughly half that he observed is "Real Conditions".

This is well known.

FWIW, this assumed what is ‘well known’ may seem to be more than a minor revelation to the many folks who have read repeatedly that mono are more efficient than poly, and come typically at a premium over poly - but admittedly the world seems a bit Orwellian today - lol
