Solar power plant comprising solar cell means (2) adapted to convert solar energy into electric energy and comprising a plurality of solar cell units (21 to 25), each solar cell unit (21) comprising a first cell pole (DC 21 +) and a second cell pole (DC 21 -), these cell poles (DC 21 +, DC 21 -) being adapted to cooperate for feeding electric energy produced by the solar cell unit (21) as direct current out of the solar cell unit (21); and direct-current converter means (4) comprising a plurality of direct-current input poles and two direct-current output poles, each direct-current input pole being connected to at least one cell pole (DC 21 +), and the direct-current converter means (4) being adapted to convert input direct currents entered via the direct-current input poles and having input voltages into an output direct current having an output voltage, and to feed the output direct current via the direct-current output poles out of the direct-current converter means (4). The direct-current converter means (4) comprise a three-phase inverter unit (11; 12) having three phase poles (L1 11 , L2 11 , L3 11 ; L1 12 , L2 12 , L3 12 ) and two direct-voltage poles (INV 11 +, INV 11 -; INV 12 +, INV 12 -), the inverter unit (11; 12) being adapted to serve as a direct-current converter in such a manner that each of the three phase poles (L1 11 , L2 11 , L3 11 ; L1 12, L2 12 , L3 12 ) are adapted as direct-current input poles and each of the direct-voltage poles (INV 11 +, INV 11 -; INV 12 +, INV 12 -) is in electrically conductive connection to exactly one direct-current output pole of the direct-current converter means (4). |
