Abstract

A solar roofing assembly is provided including a roofing membrane, a plurality of insulation blocks disposed as a layer on top of the roofing membrane, a plurality of pavers disposed as a layer on top of the plurality of insulation blocks, and a plurality of photovoltaic cells, each supported on a respective paver. In a second embodiment, each paver has a respective photovoltaic cell bonded to the top surface of the paver and has a respective insulation block bonded to the bottom surface of the paver forming a shop assembled, three-layer unit. The insulation block is also tapered with one side edge being thicker than an opposite side edge so that rain water will run off the top surface of the photovoltaic cell. The three-layer paver units are arranged on top of the roofing membrane, so that the top surfaces of the photovoltaic cells face south or in the direction of increased sun exposure. The insulation blocks have interlocking side surfaces. The joints between the pavers and the insulation blocks permit drainage therethrough of rain water for flow of rain water over the top of the roofing membrane. A method of manufacture is provided, wherein three-layer units of insulation block, paver and photovoltaic cell are made in the shop, and wherein the three-layer units are installed in the field over a field-installed roofing membrane.
