Neumann, S

A cover pane for a solar collector includes a plurality of solar energy focusing lenses arranged in longitudinal rows with the lenses within adjacent, alternative rows longitudinally offset so as to facilitate the impingement of the solar energy upon the lenses and to prevent lenses within any one row from interfering with the transmission of the solar radiation to the lenses within another row. The columnar arrangement of the lenses also facilitates self-cleaning of the cover. Each lens element is substantially ovoid or egg-shaped, as seen from a plan view, with the elongated east and west sidewalls serving to maximize early morning, evening, and winter solar radiation collection. In addition, the sidewalls are steeply sloped toward a plane normal or perpendicular to the cover base, while the front walls of the lenses are somewhat flattened. These sloped walls serve to maximize the collection of the solar energy as the sun traverses its trajectory during the solar day, as well as during the winter months when the trajectory of the sun is lower than that during the summer as known in the northern hemiphere.
