In order to increase the efficiency of a flat plate solar collector it is recommended to equip it with two mirrors so that the reflected from the mirrors solar radiation strikes the near surface of the collector. In the collector box only an absorber with a heat exchanger are placed. Both sides of the box are covered with glass panes. The collector and mirrors on a common frame are fastened. The frame on a sloping axle is mounted. The axle by an electric motor and gear-box is driven automatically be means of a step-shaped voltage generator. Such a constructor secures that the solar collector's surface is tracking the sun all the day round and solar rays are striking it perpendicularly. The goal of investigation was to look for possibilities to increase the efficiency of a flat plate solar collector by the intensification of radiation falling on the collector_s absorber.
