The main areas of large-scale development of solar energy are:- conversion of solar energy into low-grade heat, and using the latest in heating systems of residential, municipal facilities, public and industrial buildings that consume energy such as temperature capacity;- conversion of solar energy into electricity through photovoltaic and thermodynamic converters.This report provides short information of the dynamics of the creation and operation of solar power plants (SPP) with the thermodynamic conversion, and the criteria for reducing cost of electricity produced from them.
