Usually a low-iron solar safety glass is used as a transparent cover, as it transmits a great amount of the short-wave light spectrum. Absorber strip is located in an evacuated glass tube The heat transfer to the fluid flows through the absorber via a U-tube or heat pipes. Several single tubes, serially interconnected, or tubes connected to each other via manifold, make up the solar collector Consists of multiple polypropylene pipes between two chambers that are acting as an absorber. No cover, frame, or insulation.
