Solar collector technologies

HelioTrough Parabolic Trough Collector:

At the EMSP, TSK Flagsol has installed the second generation of the large-aperture parabolic trough collector: HelioTrough® 2.0. The molten salt loop is heated by four of these collectors, having a total length of 684 m and an energy collection area of more than 4,500 m². Under ideal conditions this is enough to generate up to 3,500 kW of power.
The collector technology is characterized by a continuous torque tube, rendering the collector stiff and precise. Each collector with 19-m-long elements has been manufactured in a field factory on site and lifted into place by cranes.

Advanced Linear Fresnel Reflector, ALFR-Alentejo:

The ALFR (Advanced Linear Fresnel Reflector) is a thermal solar concentrator with installed power of 270kWth and a mirror area of 440 m², with a peak concentration of 45 suns.
It includes an innovative asymmetric secondary mirror for an evacuated received tube with the possibility of placing two receivers on the same tower, achieving a higher compactness factor. It is designed to operate up to 560°C using molten salts both as heat transfer fluid and storage media.
