The aim of the invention is to build central receiver solar power plants in which the heliostat fields can be used more efficiently. To achieve said aim, a heliostat field consisting of a near field having a uniform reflector surface density &#x3c1; of more than 60% is preferably combined with a far field whose reflector surface density &#x3c1; decreases as the distance from the receiver increases. The invention also comprises central receiver solar power plants which consist exclusively of a near field having a uniform reflector surface density &#x3c1; of more than 60%. The high reflector surface density &#x3c1; in the near field and in areas of the far field is achieved by the use of heliostats having rectangular reflectors and a rigid horizontal axle suspension (FHA) or, alternatively, by heliostats having rectangular reflectors and a rigid quasipolar axle suspension (FQA). The heliostat field concentrates the solar radiation on a receiver whose target surface, aperture, thermal absorber or photovoltaic absorber has a normal vector which is directed downward to the heliostat field that extends below the receiver in the directions North, East, South and West. The receiver is mounted in a suspended manner to a support structure that extends over the heliostat field.
