A solar collector system (10, 30, 82, 82', 171) includes a photovoltaic means (24, 174) for conversion of solar energy into electrical energy and a pathway/conduit (22, 94, 94', 94") for thermal transfer fluid which is in thermal communication with the photovoltaic means (24, 174). A shaped solar concentrator surface (12, 58, 58', 173) may have at least one focus and the pathway/conduit (22, 94, 94', 94") may be disposed at the focus. The shaped solar concentrator surface (12, 58, 58', 173) may be comprised of roof cladding material (58') which is integrally formed to support the conduit (94) at the focus. Alternatively, the concentrator surface (173) may be disposed in a trough of corrugated roof cladding, with a transparent or translucent cover (98) over the top. The covers may be domed covers having an axis of curvature which substantially aligns with the roof gradient. A roofing structure comprises intersecting first (48) and second (50) roofing planes. The first roofing plane (48) extends beyond the intersection to define an extended roofing plane (54) with a cavity therebeneath housing one or more components (10, 30) of a solar collector assembly. In a particular ceiling construction, a sheeting product (112) is installed with a network (115) for liquid dispersal onto the upper surface of the sheeting product (112). The construction provides for evaporative airflow over the upper surface of the sheeting product. The solar collector may be arranged for use in a cooling/heating system based on an absorption refrigeration system. |
