Do any of the standard PV module listing or certification tests cover resistance to impacts from objects like golf balls?
Some quick googling tells me a golf ball weighs roughly 6 times as much as a 1" ball of ice. Not very auspicious.
Made of transparent aluminum? (Star Trek)Make a chicken wire grill to protect the panel .

Actually the grille will intercept exactly the same fraction of the sunlight no matter what distance it is at. You will just avoid visible sharp edged shadows. As long as the shadows only cover a small percentage of each cell there should not be a problem, other than the overall reduction of light on all cells uniformly and proportionally.haha no, the wire should be thin enough so that its cross section wont cast much of a shadow and reduce power output... might lose a few %, tho moving the grill away from the panel would minimize losses
