SOLAR PHOTOELECTRIC MODULE WITH CONCENTRATOR Russian patent published in 1999 - IPC

FIELD: solar power engineering; power and heat generation. SUBSTANCE: module has full-reflection prisms 1,2 with photoconverter 3 placed between them. Each prism has effective surface 4 receiving incident rays and rear mirror coating 5. Mirror 6 is mounted on one side of concentrator. Designations on illustration mean: β is input angle of rays; ϕ is angle at prism apex; L is prism width; d is photoconverter width; l is mirror width; γ is angle between mirror and vertical line to module surface. Solar module is mounted with its axis horizontal and aimed at west-east or at certain angle to horizontal line so that minimal input angle β occurs in June 22 (summer solstice day). β angle at prism apex is chosen according to ϕ angle. EFFECT: improved optical efficiency and, hence, concentration of sun rays. 3 cl, 3 dwg
