The article considers a low-energy wind and solar stand-alone power system for agricultural consumers. The wind generator used is a 500 W dual magnetic synchronous generator, and its structural diagram, magnetic flux density distribution chart, mathematical modelling and the field test results are presented. The article also describes a linear drive solar panel tracker. The tracker structure and design and the field test results for a solar collector with the solar tracker are presented. A synchronous generator with a two-circuit magnetic system contains an external and internal circuit on which neodymium magnets, a magnetic core, additional poles are fixed. Between external and internal circuits the generator stator windings are arranged. The body of the synchronous generator, on which the external and internal magnetic circuits are fixed, is made of plastic. The excess energy produced by a synchronous generator with a double-circuit magnetic system is accumulated in the batteries, in case of lack of wind load, simultaneous operation of a synchronous generator with a double-circuit magnetic system and a battery through a power controlled transistor to the inverter is possible. Tracking system of the sun contains the sensor of position of the sun, two DC motors with gearboxes and retractable stocks, allowing to position the solar panels in two planes, horizontally and vertically depending on the position of the sun, allowing to increase the power generation of solar panels compared with the stationary arrangement of 40 %.
