Abstract: A photovoltaic module includes a pyramid-shaped body having an open top end, a closed bottom end, and a hexagonal wall extending between the top end and the bottom end that defines a light receiving cavity. The wall tapers in diameter from the top end to the bottom end and includes slanted light receiving surfaces and planar light receiving surfaces including photovoltaic cells configured to convert sunlight to electricity. The planar light receiving surfaces are disposed between the slanted light receiving surfaces and parallel to the bottom end. The slanted light receiving surfaces slope inward toward the cavity and the bottom end relative to the top end such that the slanted light receiving surfaces face the top end. The planar surfaces form steps in the wall that interconnect the slanted light receiving surfaces. The slanted light receiving surfaces and the planar light receiving surfaces are concentrically aligned relative to one another.
