An adjustable solar powerer having photovoltaic cells made of either silicon, polycrystalline or single-crystalline located on a stabilizing base converts solar power or artificial light into electric energy. This solar powerer is made up of unilateral flat and movable elements, each having unilaterally installed photovoltaic cells, these elements being connected with each other by a yoke and catch at one end, the yoke and pivot being connected to a tripod.
