Ground based single axis concentrating system
Parabolic trough solar fields offer excellent specific heat output and a strong yield per square meter of land used. Rackam’s solar fields utilize the S21 series of parabolic troughs—robust, single-axis concentrators designed for durability, minimal maintenance, and ease of installation. These collectors are optimized to deliver consistent thermal energy performance while keeping operational costs low.
A Rackam solar field consists of multiple rows of S21 concentrators arranged in a single-axis configuration. A distributing manifold at one end of the field directs a heat transfer fluid through the collectors, where it is heated by concentrated sunlight. The heated fluid is then gathered by a collecting manifold at the opposite end and sent to a heat exchanger. There, it transfers its thermal energy to the industrial process loop. A fully instrumented pumping module ensures continuous fluid circulation and real-time monitoring of system parameters, supporting efficient and reliable operation.

The S20 series, robust and durable medium size parabolic throughs
The S21 Parabolic Trough series redefines how industrial solar energy is deployed. Engineered for rugged, real-world conditions, it combines high efficiency with rock-solid durability.
Every detail of the S21 has been carefully thought through to make your installation easier, faster, and longer-lasting:
- Minimal parts mean fewer things to go wrong — and faster assembly
- Modular design lets you grow your solar field as your needs evolve
- No on-site welding — just bolt, align, and go
- Simplified alignment system for perfect setup without specialized tools
- Protective rotating wheel: in minutes, your mirrors can rotate out of harm’s way, shielding them from snow, hail, or sandstorms
Thanks to this unique protective feature, the S21 isn’t limited by climate.
It thrives in the snow, in the desert, and everywhere in between — ensuring your investment is protected no matter what nature throws at it. Whether you’re heating industrial processes or powering a hybrid energy system, the S21 gives you the confidence to build solar energy wherever you need it.
