In this paper, the design of a triangular built-in storage-type solar water heater with transparent insulation on the top and sides is studied under various operating conditions. The transient performance of the system is studied by using a finite-difference forward time-step marching technique....

We have considered the general case of a collector with four reflectors. An analytical model is developed for study of the effect of an individual reflector on the collector. Reflectors R-1, R-2, R-3, and R-4 face south, north, west, and east, respectively. For a collector with two reflectors...

This paper presents transient analysis of an evacuated tubular solar collector. Basic energy balance equations for the glass envelope, the absorber and the fluid are solved using the finite difference technique to predict the various component temperatures as a function of time. Four versions of...
