Conclusions.Renewable energy sources are typically used to meet the energy needs of the consumer. This is due to the desire of the latter to invest in "green" energy, as well as to receive additional energy of high quality.In Ukraine, it is possible for owners of private households to sell excess generated energy from RES at a "feed-in tariff", which is an additional incentive for switching to RES. The combination and use of several elements of renewable sources will help achieve sustainable electricity supply due to the synergistic effect of their hybridization. Since such systems are still underdeveloped in Ukraine, there is a need for their further researches and improvements.
