NOVELTY - A roofing, cladding, or siding module (300) comprises an underlapping region (301) and an exposed region, where the underlapping region is adapted to be covered by the exposed region of an adjacent module when installed on a building surface; and an outer surface and an under surface, where the under surface of the underlapping region is profiled to define a pathway for air flow between the module and the building surface.    USE - As roofing, cladding, or siding module, for generating electricity and recovering thermal energy from building surface (claimed).    ADVANTAGE - The roofing, cladding or siding product which is light weight, easy to install, weatherproof, durable, resistant to environmental wear, and aesthetically pleasing.    DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following:    (1) roofing, cladding, or siding assembly comprising partially-overlapping modules that covers a building surface, where each module comprises an underlapping region and an exposed region, where the underlapping region is adapted to be covered by the exposed region of an adjacent module when installed on a building surface and the exposed region is adapted to be exposed when installed on a building surface; an outer surface and an under surface, where the under surface of the underlapping region is profiled to define a pathway for air flow between the module and the building surface; and    (2) system for removing or recovering thermal energy from a building surface, comprising a building surface, a roofing, cladding, or siding assembly, and a fan adapted to induce the air flow;    (3) system for generating electricity and recovering or removing thermal energy from a building surface comprising a building surface, a roofing, cladding, or siding assembly where the outer surface of the exposed region comprises photovoltaic cells;    (4) removing or recovering thermal energy from a building surface involving inducing an airflow to pass through an air passage between a building surface and an under surface of partially-overlapping modules that cover the building surface, where each module comprises an underlapping region and an exposed region, where the underlapping region is adapted to be covered by the exposed region of an adjacent module when installed on a building surface and the exposed region is adapted to be exposed when installed on a building surface; and an outer surface and an under surface, where the under surface of the underlapping region is profiled to define a pathway for air flow between the module and the building surface;    (5) method for simultaneously generating electricity and recovering thermal energy from a building surface, involving inducing an airflow to pass through an air passage between a building surface and an under surface of partially-overlapping modules that substantially cover the building surface, and collecting electrical energy from photovoltaic cells present on an exposed surface of the modules, where each module comprises an underlapping region and an exposed region, where the underlapping region is adapted to be substantially covered by the exposed region of an adjacent module when installed on a building surface and the exposed region is adapted to be exposed when installed on a building surface; and an outer surface and an under surface, where the under surface of the underlapping region is profiled to define a pathway for air flow between the module and the building surface; and    (6) manufacture of a roofing, cladding, or siding module, involving providing to a continuous forming machine a feed material able to assume and retain a form after being molded between a first forming surface and a second forming surface, allowing the formation to take place as such surfaces are advanced in the same direction, where the output is a roofing, cladding, or siding module comprising an underlapping region and an exposed region, where the underlapping region is adapted to be covered by the exposed region of an adjacent module when installed on a building surface; and an outer surface and an under surface, where the under surface of the underlapping region is profiled to define a pathway for air flow between the module and the building surface.
