Annotation: This article describes comparison of parallel and serial Solar Array power regulators. It presents the comparative analysis of the energy efficiency of the power conditioning units with parallel and serial Solar Array power regulators, including the max power point tracker usage The analysis showed that the energy characteristics of the power supply system based on energy conversion equipment with a serial power regulator using an extreme solar battery power regulator are equivalent to the energy characteristics of the power supply system based on energy conversion equipment with a parallel solar battery regulator for geo-stationary orbit. Usage of the max power point tracker with the serial regulator gives gain by 1 m 2 of Solar Array square at output power level of 6 kW in other equal conditions.

Keywords: power conditioning units, serial regulator, parallel regulator, max power point tracker, spacecraft electric power system
