A display apparatus includes a display, a primary light concentrator, a concentrator light guide, and a solar cell. The primary light concentrator is arranged in tandem with the display, and the primary light concentrator is configured to concentrate incident light into an array of output regions. The concentrator light guide receives light from the primary light concentrator. The concentrator light guide includes light redirecting elements aligned with the output regions of the primary light concentrator to redirect light from the primary light concentrator along the concentrator light guide toward an edge thereof. The solar cell is located adjacent the edge of the concentrator light guide.
