Advance Solar Thermal
Brayton Turbine System
Solar Catcher™ system
is a concentrating solar
power Dish technology
equipped with a Brayton
Turbine special designed
insolation, soft‐land, hot
and humid country zone
such as Asia Zone.
Its mission is to build the most affordable, modular and
scalable solar solution in the industry for utility scale solar
Parabolic Dish systems use mirrors to focus the incident
light onto a single central receiver in front of the mirror. They
so far have the highest heat‐electricity conversion efficiencies
among all CSP designs up to 65 %.
The size of the concentrator is determined by its engine. A
dish/Brayton Turbine system’s concentrator with a nominal
direct solar insolation from 500‐1,000 W/m2 and a 2‐100 kWe
capacity has a diameter of approximately 3 to 20 meters.
It could also run on a single Rankine or Brayton cycle,
where water, or other gas is compressed, heated and
expanded into a turbine. Parabolic dish could be applied
individually in remote locations, or grouped.
For small‐grid (village power, 2 ‐ 10 KW) or end‐of‐line
utility (1 ‐ 100 MW) applications. The system had no thermal
delivery tubes so it is minimum thermal losses.
The electricity transmitted to the gird or storage in
Vanadium Batteries. Intermittent cloud cover can cause
weakening of highly concentrated receiver source flux.
Sensible energy storage in single‐phase materials was
proposed to allow a cylindrical absorber element not only
absorb the energy but also store it in its mass, thus
reducing the amplitude of cloud cover transients. Although
this design only allows short period energy storage.
It could equipped with Vanadium Battery or Thermal
Storage for longer operation time, 6, 12, 24 hrs.

Thailand. Solar Catcher™,
CSP technology is a 2, 5,
10, 25, or 100 kWe
The SFI, Solar Catcher™, achieved commercial deployment
in early 2013. It’s clean solar energy.
The Solar Catcher™ technology makes it possible for
large power facilities to provide clean, reliable, cost‐
effective and truly sustainable solar power to communities,
while addressing renewable energy portfolio targets, and
tackling global climate change by actively reducing our
planet’s carbon emissions.
