This document from 1999 was prepared by the American Solar Roofing Company and explains building integrated solar thermal (BIST) designs.
There are four characteristics mentioned in this report to help distinguish the different types of BIST roofing: roof panel size, heat transfer fluid containment, glazing and focusing methods. It discusses the history of BIST and mentions some of the earliest examples of this technology. It also explains the composition of these systems, describing the materials used and how it works.
Before the drawn conclusions, it also shows a study done on solar roofing tile energy delivery.
