DEVELOPMENT OF A FACETED CONCENTRATOR FOR A COMBINED PHOTOVOLTAIC PLANT

This article examines the features of solar energy concentrators. The characteristics currently existing types concentration systems are given: a weak system and high system. Their design shortcomings given. It is noted that Frenel lenses one most widely used concentrators, but their optical efficiency limited by low or temperatures, as change in refractive index deformation lens structure observed due to thermal expansion. Fresnel lenses, which focus radiation on an area ​​up 1 cm 2, do not allow utilization excess energy. complex geometric shape parabolic concentrators determines expensive technology manufacture, which, turn, significantly increases cost electric produced them. Luminescent have coefficient conducted analysis showed create competitive compared traditional sources electrical photo-energy installations work at levels utilize In order solve mentioned problems, authors developed faceted concentrator radiation, gave its presented laboratory sample. Questions optimization adjustment investigated. A report mock-up tests has been published.
