Efficiency estimation for the grid-tie photovoltaic stations construction in some regions of Central Asia and Transcaucasia

An assessment of the economic expediency of the construction of network photovoltaic stations in some regions of Uzbekistan, Kyrgyzstan, Tajikistan, Turkmenistan, Kazakhstan, and Azerbaijan is presented, with an accounting for climate conditions and the electricity rates that were adopted to encourage the development of renewable power engineering. The analysis covers design variants of 5-MW model solar power plants on photovoltaic modules made according to various technologies with respective modern and advanced cost indicators. The performance indicators of PVPPs with multicrystalline photovoltaic modules and highly efficient HIT technology modules were made by the Hevel company in Russia.
