Abstract
A local concentrator apparatus is described. The apparatus includes an array of photovoltaic cells arranged along an elongated strip, and one or more optical elements. The one or more optical elements are arranged to direct and optically concentrate sunlight onto the photovoltaic cells such that position that the directed sunlight impinges onto the strip follows a path moving along the strip without the optical elements tracking the sun as the sun traverses the sky during the day.
