Solar energy concentrator with tracking parabolic reflector, has lower edge adjacent to support plane and pivotal axis

摘要: The invention relates to a concentrating solar energy system, comprising reflector (10) in the form of parabolic mirror, guided two axes, supported on base frame (14), arranged support plane and receiver (62) for operation at focal point (110) whereby mirror may also be rotated about an axis (36) essentially perpendicular plane. is characterised that during operation, has lower edge (12) least directly adjacent plane, which either straight or slightly curved plan. tilted up down tilting (36), region thereof, parallel linearly moved (14).
