SolaRoll is a solar collector material composed of extruded strips of black ethylene propylene diene monomer (EPDM) that is suitable for water or air type collectors. SolaRoll is provided in rolls and consists of an absorber mat with tubes and fins and a framing strip comprising all the parts of the collector frame. The rolls are bent in a counterflow pattern to cover the entire collector area and the mat is fastened with a thermosetting mastic adhesive. The heat transfer fluid is plain water as freezing does not injure the EPDM. Installation of the glazing in the framing strip is described. EPDM has the disadvantage of low thermal conductivity but its use does not require antifreeze or a heat exchanger. Design options and suitable applications of SolaRoll systems are discussed.
