Dave Crowlie is right.At the moment,Mono solar panels efficiency is about 16% and poly solar panels efficiency is about 13%.

Solar panels are not 2/3 efficient. They are made in a range of efficiencies, from 12-19%. Once you get done with temperature variations, inverter loads, you can really only count on 10-12% of the watt rating on the panel actually coming out of the panels to the battery bank or utility intertie. Sure, there are advances claiming up to 40% efficiency, but they are not “on the ground”, and available to you or I. Check the NREL website on “the latest”, but don’t expect to buy these vanguard panels for a while.

What we need is a coating that can integrate into the common roof shingle. Make every home built with its own in-built power source, with bi-directional grid connectivity. If this substance can move us in such a direction, awesome!
