DETERMINING THE ECONOMIC EFFICIENCY OF A PHOTOVOLTAIC PUMPING UNIT
Keywords:
solar energy, photovoltaic installation, pumping installation, net present value, levelized cost of energy, payback period, life cycle cost of plant.Abstract
The article discusses the issues of the efficiency of solar energy supply to electric
motors of pumping units used in irrigation systems in different countries of the world. A methodology
for 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 calculations
of a photovoltaic pumping unit with a capacity of 100 kW, performed according to the proposed
methodology, are presented.
