Solar energy collector module system

Abstract From the Canadian patent

The invention disclosed is a solar energy collector apparatus having several double-wall glass tubular elements connected on opposite sides of an elongated manifold to form a module. The elements are sealed in oppositely facing metal cups and inside the opposite elements is a cross supply tube. The cups in a module are series connected by conduits for flow of a liquid through the collectors. Along the manifold are two header pipes respectively connected to the cups for introducing liquid to the collectors for series flow and for receiving heated liquid flowed through them. The headers solar heated liquid. The cups, header pipes and interconnecting conduits are enclosed in an insulation …
