Savchenko E. The Economic Effectiveness of Solar Energy Utilization in Agricultural Enterprises.

This paper summarizes theoretical and methodological foundations of economic effectiveness of solar energy utilization in agricultural enterprises and forms the methodology of determination of its indexes. The analysis of power supply is done at agricultural enterprises using renewable power sources. The tendencies of solar energy utilization at agricultural enterprises of Ukraine and foreign countries are researched. The factors influencing on effectiveness of solar energy utilization in technological processes at agricultural enterprises are analyzed. The paper provides methods of quantitative evaluation for economic and ecological effect of carbon trading and prevention of adverse health effects caused by atmospheric emissions from thermal power stations. Economic and mathematical model of optimization of configuration and typical size of power equipment for the criterion of cost minimization are developed and solved in this research paper. The researcher determines predictable factors of economic effectiveness of substitution for electrical power to solar power and effectiveness of investment projects.
