Low-Cost Solar Thermal Collector
SunTrough, under the Baseload CSP FOA, is developing a new class of solar concentrators with geometries and manufacturability that can significantly reduce the fully installed cost of the solar collector field.
SunTrough Energy is working to develop a single-axis tracking, line-focus solar concentrator and a pilot manufacturing facility under this award. The new Articulating Planar Fresnel Collector (APFC) design is supported by dedicated component manufacturing facilities and supply chain management.
The APFC incorporates the geometry of the linear Fresnel reflector with the single-pivot tracking of the conventional parabolic trough collector. This has two distinct advantages over existing CSP designs:
- Compared to a parabolic trough, the unit is subjected to lower wind loads, which translates into less structural support metal and smaller/simpler foundations and drives.
- Compared to a linear Fresnel, the unit eliminates the individually tracked mirror facets.
The design utilizes a stationary receiver and near-flat linear mirror sections assembled in a planar section. The APFC is designed with smaller, identical parts for mass manufacturability and rapid field integration.
