The Overview of Basic Types and Characteristics of Solar Concentrating Modules With Louvered Heliostats

Abstract

The principles of construction and operation of the main concentrating systems, including non-followable modules, are reviewed, and the work of the concentrators is analyzed. An analytical review of modern facade-integrated photovoltaic technologies was carried out, and their classification was given. The known methods for calculating a flat (two-dimensional) scheme for passing the sun's rays through a louvered heliostat make it impossible to assess the real effectiveness of using louvered heliostats with non-tracking solar concentrators, which makes it necessary to consider the practically important three-dimensional problem of calculating the solar radiation flux on the receiving surface of an unfollowing parabolic-cylindrical solar concentrator with louver heliostat.
