Photo-electric installations (PEIs) became widespread in the world practice. They function in a system of autonomous and local power supply. In many countries well-known programs “solar roofs” are introduced. Under this name PEIs, mainly, in a form of flat PEMs, are meant, which are placed on roofs of buildings, including individual living houses. There were also many constructive solutions developed, the so-called “building integrated photovoltaic’, that is, PEMs in-built in construction, which are simultaneously its architecture-constructive units: parts of walls, roofs, screens.
