摘要
A low-cost system for increasing the electricity generation of flat panel photovoltaic (PV) farms in which sunlight redirecting elements are positioned in offset spaces provided between adjacent panel assemblies and serve to redirect otherwise unused sunlight onto solar cells disposed on one of the panel assemblies. The redirecting elements are located in a prismatic volume bounded at its upper end by an inclined upper plane that extends across the offset space separating adjacent PV panel assemblies. The redirecting elements are either mounted to at least one of the PV panel assemblies, or placed on the ground between the assemblies. Each redirecting element includes multiple reflecting and/or refracting surfaces that utilize a disclosed microoptical arrangement (e.g., focus and steer or reorient and scatter) to distribute the redirected sunlight in a substantially homogenous (uniform) distribution on the solar cells.
