Have encountered another wrinkle in the poor performance of solar panels.
Quote:It is not widely known existing solar cell systems only produce electricity six hours a day. Where silicon cells are delicate they need to be shielded with glass covers. At any angle below 45 degrees the shields reflect 90% of an "incident beam" of sunlight and 100%, below 30 degrees, keeping it from the cells. This is not a property of glass, but the physics of surfaces. No transparent material lets sunlight through completely at any angle of incidence below 45 degrees.
Environmentalism is based on lies and the lies reflect an agenda that regards humanity as the enemy of the Earth. - Alan Caruba
