The article discusses the issues of the efficiency of solar energy supply to electricmotors of pumping units used in irrigation systems in different countries of the world. A methodologyfor calculating modern indicators of the economic efficiency of photovoltaic pumping units is given,such as the cost of the unit during its service life, net current (present) income, normalized (present)cost of generated energy and the payback period of capital expenditures. The results of calculationsof a photovoltaic pumping unit with a capacity of 100 kW, performed according to the proposedmethodology, are presented.
