Purpose. The aim of the article is substantiation of theoretical bases of RES use and practical aspects of economic efficiency of various projects on use of solar energy depending on territorial conditions of the enterprises of agrarian and industrial complex of Ukraine as a factor of resource saving and energy efficiency.

Methodology of research. Dialectical methods of cognition of processes and phenomena, economic, financial, comparative and monographic methods (for analysis and evaluation of the effectiveness of RES in different territorial conditions of Ukraine), are used to achieve this goal as well as abstract and logical method (for theoretical generalizations, conclusions).

Findings. The efficiency of solar energy use in different territorial conditions of Ukraine is substantiated. The efficiency of projects under different scenarios of production of agro-industrial complex (drinking water) is calculated on the example of PJSC “Dobra Voda” of Zboriv district of Ternopil region. It is established that the most effective project for this enterprise in all studied production scenarios is a project with a capacity of 1 MW, the second place in terms of efficiency is occupied by a project with a capacity of 850 kW, in third place ‒ a project with a capacity of 700 kW, and the least effective is a project with a capacity of 585 kW.

The economic efficiency of investment projects in the dynamics of 25 years using discounting methods was studied and it was found that the project with a capacity of 1 MW is the most effective in all scenarios of production at the enterprise. It is concluded on the basis of an in-depth study of the effectiveness of existing projects in different territorial conditions of Ukraine that these projects for the use of solar energy in the eastern and southern regions of the country may have better performance indicators of economic efficiency 1.5-2 times.

Taking into account the experience of the EU-28, it is substantiated that in Ukraine, which has a strong biological potential, the priority should be to accelerate the development of bioenergy, which will increase RES and on this basis to replace gas and oil, reduce production costs, improve its competitiveness; to clean the environment in all regions of the country; increase the number of jobs and improve the social and economic living conditions of the population.

Originality. Theoretical approaches to the assessment of economic efficiency of projects of different capacity for the use of solar energy according to the options that take into account the territorial features of their implementation at the enterprises of the agro-industrial complex of Ukraine are substantiated.

Practical value. The main provisions and conclusions set out in the article contain methodological and practical recommendations for the formation of a system of resource conservation and the use of renewable energy sources at enterprises.
