Abstract: Disclosed is a solar system comprising a solar panel (1) that is composed of spaced-apart modules (11-14) which are oriented in a North-South direction in an inclined position. The modules (11-14) are mounted on a support (15) which is in contact with an adaptively program-controlled electric drive (5). Said electric drive and thus the entire panel (1) are time-dependently swiveled about a stationary shaft (6) so as to obtain maximum solar radiation. The drive (5) is self-sufficiently powered by a solar module (11), thus dispensing with the need for solar sensors and auxiliary power supplies. An operating method aims to maximize solar output while taking into account the duration of daylight. The inventive system is used particularly for supplying emergency power to sensitive infrastructures. Several systems can be mechanically or electrically connected to each other according to the master-and-slave principle so as to create a solar park and be part of a large power system.
