Optimal solar energy collector system
TL;DR: In this paper, the problem of designing solar energy collectors for the delivery of heat at minimum cost is analyzed in two different forms: in the first form, a set of collectors is assumed to be available, each element having different properties uniformly distributed over its area; an optimal design is achieved by a suitable combination of a subset of such collectors.
