Abstract
A system for generating electricity from solar energy comprises a first vertically-oriented bifacial photovoltaic module, a second vertically-oriented bifacial photovoltaic module positioned a horizontal distance form the first bifacial photovoltaic module, and a macro-textured structure positioned between the first and second bifacial photovoltaic modules. The macro-textured structure includes a plurality of protruding features having reflective surfaces, and the protruding features are operative to reflect light incoming within a range of 0 to 10 degree of vertical toward the first and second bifacial photovoltaic modules.
Claims15
A system for generating electricity from solar energy comprising:
- a plurality of adjacent pairs of vertically-oriented photovoltaic modules, each adjacent pair of the plurality including:
- a first vertically-oriented bifacial photovoltaic module;
- a second vertically-oriented bifacial photovoltaic module positioned a horizontal distance form the first bifacial photovoltaic module;
- and
- a macro-textured structure positioned between the first and second bifacial photovoltaic modules, the macro-textured structure including a plurality of convex protruding features each having respective reflective surfaces that reflect, diffuse and scatter incident solar radiation at various angles toward the first and second bifacial photovoltaic modules,
- wherein the protruding features are operative to reflect light incoming within a range of 0 to 10 degree of vertical toward the first and second bifacial photovoltaic modules.
An apparatus for improving the midday energy yield of a solar energy facility including a series of vertically-oriented bifacial photovoltaic modules, the apparatus comprising:
- a macro-textured structure adapted to be positioned between adjacent modules of the series of bifacial photovoltaic modules, the macro-textured structure having surface including a plurality of protruding features having reflective surfaces that are operative to reflect light incoming within a range of 0 to 10 degree of vertical toward the first and second bifacial photovoltaic modules;
- and
- a plurality of drainage holes positioned between adjacent protruding features on the macro-textured surface, the drainage holes adapted to remove dust and moisture from the macro-textured structure.
