SOLAR PANEL TESTING: THE NORTH, EAST, SOUTH, WEST & ROOF FACADE WERE TESTED WITH THREE OPPOSING SOLAR PANEL SETS. EACH SET CONSISTED OF 18 FINS, ROTATED 5 DEGREES FROM 0-90. THIS METHOD WOULD ENSURE THAT THE BEST SUN ANGLE WOULD BE ACCURATELY DETERMINED. 2 SETS RAN VERTICALLY, ONE WAS PLACED HORIZONTALLY ACROSS THE FACADE. 90 DEGREES PERPEN180 DEGREES PARALLELDICULAR TO FACADE TO FACADE
