This paper comes from the National Renewable Energy Laboratory (NREL). It reports on new technology being used in solar thermal systems, and the materials and designs that make this solar thermal technology possible and feasible for consumer deployment.
Polymer materials and advanced manufacturing techniques used in solar thermal technology can cut costs by 50% and make parts that are easier to install. NREL has provided modeling and testing for two new models, one thermosiphon and one intergral collector storage system. NREL has been able to solve the pipe freezing problem in these designs which will allow use in cold climate settings.
