Concentrating solar roofing shingle

摘要: This invention describes a non-imaging, non-tracking, integrally-formed solar radiation concentrator that passively concentrates both diffuse and direct onto photovoltaic cells to produce electricity, incorporating its features into shingle-like element useful as roofing material in other structural applications. The substantially transparent, concentrating elements of the may also incorporate system remove waste energy form heat is not utilized generation electricity. further provides thermal recovery including forced convection air for removing from shingle assembly using it, if desired, building space or domestic water heating.
