What are Solar Thermal Collectors?

solar thermal collectors nrel Collectors are the tools that transfer the light and radiation generated by sunlight (typically UV radiation) into heat. This heat can then be transferred to an HTF (Heat Transfer Fluid) and storage medium, such as water (or a water – glycol solution), providing a completely free heat source, which then cuts down on the amount of fuels (oil, propane, natural gas, wood, etc) used for various heating applications around the home or office.
