Abstract

One of the most promising means of improving the performance of solar thermal collectors is by reducing the energy lost by the host absorber. One way to do this, not currently part of the technology, is by recognizing that the absorber is usually not irradiated uniformly. Therefore it is possible to construct an absorber of thermally isolated segments, circulate the fluid in sequence from low to high irradiance segments, and reduce loss by improving effective concentration. This procedure works even for ideal concentrators, without violating Winston's theorem.
