Details

A Parabolic Trough Collector (PTC) integrated with a Thermal Energy Storage (TES) system is a highly effective concentrated solar thermal (CST) technology that addresses the intermittent nature of solar energy by allowing for continuous operation, even after sunset or during cloudy periods. The PTC utilizes a large, trough-shaped, mirrored surface to focus direct solar radiation onto a receiver tube positioned along the focal line. A heat transfer fluid (HTF) flows through the receiver tube, where it is heated to high temperatures up to 350 oC.
