<p>A photovoltaic roofing assembly comprises a roofing membrane ( 102 ), a plurality of photovoltaic modules ( 104, 106, 108 ) disposed as a layer on top of the roofing membrane ( 102 ), and a plurality of pre-formed spacers, pedestals or supports ( 112, 114, 116, 118, 120, 122 ) which are respectively disposed below the plurality of photovoltaic modules ( 104, 106, 108 ) and integral therewith, or fixed thereto. Spacers ( 112, 114, 116, 118, 120, 122 ) are disposed on top of roofing membrane ( 102 ). Membrane ( 102 ) is supported on conventional roof framing, and attached thereto by conventional methods. In an alternative embodiment, the roofing assembly may have insulation block ( 322 ) below the spacers ( 314, 314', 315, 315 '). The geometry of the pre-formed spacers ( 112, 114, 116, 118, 120, 122, 314, 314', 315, 315 ') is such that wind tunnel testing has shown its maximum effectiveness in reducing net forces of wind uplift on the overall assembly. Such construction results in a simple, lightweight, self-ballasting, readily assembled roofing assembly which resists the forces of wind uplift using no roofing penetrations.</p> |
