WebbIn aerodynamics, Betz's law indicates the maximum power that can be extracted from the wind, independent of the design of a wind turbine in open flow. It was published in 1919 by the German physicist Albert Betz. The law is derived from the principles of conservation of mass and momentum of the air stream flowing through an idealized "actuator disk" that … WebbThe maximum theoretical efficiency calculated is 86.8% for a stack of an infinite number of cells, using the incoming concentrated sunlight radiation. [9] When the incoming radiation comes only from an area of the sky the size of the sun, the efficiency limit drops to 68.7%. [10] Ultimate efficiency[ edit]
