A photovoltaic roofing assembly comprises a roofing membrane (102), a plurality of photovoltaic modules (104, 106, 108, 110) 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 di
A photovoltaic roofing assembly comprises a roofing membrane (102), a plurality of photovoltaic modules (104, 106, 108, 110) 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, 110) 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 a tapered profile for orienting modules (204, 206, 208, 210) in a direction of increased sun exposure. Other embodiments include the use of phase change material for temperature regulation, and incorporating an insulation block into the assembly as a means of spacing and of building thermal control. Such construction results in a simple, readily assembled roofing assembly which regulates the temperature of the photovoltaic module and roofing membrane and avoids the need for rooting penetrations for hold-down to the building rooftop. Photovoltaic modules (104, 106, 108, 110) serve the purpose of electric generator, and in addition, the multiple purposes of ballast, UV block, and weather protector for the insulation block and roofing membrane below. A fluid convects within the passageways created by the spacers, transferring heat from the backside of the photovoltaic modules. Rainwater drains through the joints between the integral modules, onto and over the roofing membrane below.
