FIELD: heating.SUBSTANCE: solar module with a concentrator consists of a solar radiation receiver and a cylindrical solar concentrator, the reflecting surface of which is formed with rectangular mirror-reflecting plates-facets. Facets are installed so that solar beam L1 lying in the cross-sectional plane of concentrator and having a deviation from target direction to the Sun, which is equal to accuracy of the tracking system, and after it is reflected on the facet edge that is the closest one to the receiver, it falls down to the boundary of concentrated solar radiation zone on the receiver surface, which is located far from it, and width of facets is such that beam L2 that is symmetrical to the first beam L1 relative to target direction falls down to the nearest boundary of concentrated radiation zone after it is reflected on the opposite facet edge.EFFECT: more uniform distribution of solar radiation along the receiver surface; improving optical effectiveness of a concentrator; increasing average annual power generation and reducing its prime cost.4 cl, 6 dwg |
