The methodology of determining the energy potential of the wind at the location 145,39 kWh•m -2 of the two-rotor wind power installation for further use in agricultural producers far from the power supply networks is substantiated. The wind power potential of the area and the site, on which the two-rotor wind power installation is installed, allow to conduct full-scale tests for the operability and reliability of the developed installation. A description of the metrological support for determining the energy characteristics of a two-rotor wind power installation (RWPI) is given, including the experimental setup scheme and its general view. A methodology for processing experimental data has been developed and the results of full-scale tests of a tworotor wind power installation in conditions close to real terrain are presented. The calculation of the power of the two-rotor wind power plant varied from 0.015 to 27.401 kW using the characteristics of the wind potential confirms that it produces sufficient power to charge the batteries included in the battery fleet of agricultural producers. The results of full-scale tests of a two-rotor wind power installation showed that it can be used by separate energy consumers with a wind flux utilization factor of at least 0,32 and allows further selecting power and operational parameters of mechanisms and machines using mechanical energy of a vertically rotating rotor shaft of the wind power installation.
