Photovoltaic systems and methods for optimizing the harvesting of solar energy are disclosed. A photovoltaic (PV) system includes: a solar panel module. The solar panel module comprises: a plurality of solar cell arrays, wherein each array comprises a grouping of solar cells; and a tubular panel. The plurality of solar cell arrays are arranged along an inside surface of the panel. At least an upper portion of the panel slopes inward such that the panel has a substantially funnel-shaped geometry. The solar cell arrays are arranged in a C-ring pattern. A first solar cell array is separated from a second solar cell array by a predetermined distance. The area between the solar cell arrays is coated with a reflective material to facilitate optimal reflection of incident sunlight back to the solar cells. Recycling of incident light is facilitated within the tube. The light can be intermittently or continuously recycled.
