A modular photovoltaic system adapted for collecting light rays from a solar light source to generate electrical current, the system having a light-tracking solar collector adapted to collect the light rays, an edge-lit photovoltaic array, and a transport conduit adapted to transport the light rays to the edge-lit photovoltaic array. The edge-lit photovoltaic array has a plurality of edge-lit photovoltaic panels, each having a transparent diffusing pane positioned between two backing panels with inwardly directed photovoltaic surfaces. Each edge-lit photovoltaic panel perpendicularly contacts a lateral light distributor attached to the transport conduit, causing the transparent diffusing pane to illuminate the photovoltaic surfaces to generate electrical current. The light-tracking solar collector is adapted to rotate to remain oriented toward the solar light source.
