Abstract
A solar collector panel is made from glass fiber reinforced concrete using a dissolvable core of polymer foam to form the internal passageways. The core is dissolved in a solution of solvent and polymer which impregnates and coats the concrete surfaces of the passageways to seal the passageways and to isolate the concrete from the heat transfer fluid.
