Abstract: Components mount an array of solar panels to trapezoidal metal roofs or flat or low-slope roofs. Couplings may secure a trapezoidal metal roof mounting adapter to the peak of the trapezoidal portion of a trapezoidal metal roof, and couplings may secure additional mounting hardware to the adapter. Solar panels may connect to the rear portion of one support and the front portion of another support to achieve an angled installation to improve sun exposure. Wind diffusers may connect to solar panels to form a barrier extending from the upper-most edge of the installed solar panel downward toward the roof to impede wind. The flat and low-slope roof solution may comprise a penetration-free mechanism to install solar panels at an angle on a flat or substantially flat surface while impeding effect from wind and maintaining an electrically grounded connection between all components.
