Abstract: Dynamic analysis of energy data can help improve the efficiency of buildings in several ways: evaluation of proposed modifications of a building or its operation (e.g., changes in thermostate ...

Abstract: The incidence-angle modifier for parabolic troughs is investigated in order to clarify the connection between collector tests and prediction of long-term energy delivery by collector arrays. The ...

Abstract: Circumsolar radiation is one of several factors, along with optical errors (contour, tracking, etc.), that determine the size and shape of the solar image at the receiver of a concentrating ...

Abstract: This paper describes a novel alternative to the laser ray trace technique for evaluating the optical Quality of focusing solar collectors. The new method does not require any equipment beyond ...
