The New DesignLower Tower - Experiment
The flexural tests are carried out
by using three point bending
specimens and the flexural
property was determined
according to ASTM D790 with the
specimen dimensions of 42 mm
diameter, support span of 160
mm and crosshead speed of 0.5
mm/min. The Flexural test using three point
bending specimen

The New DesignLower Tower - Experiment
As a result of these experiments it
is obtained that the specimen 4
shown in Figure 4 has the
highest-strength when compared
with others since the cement and
glass fiber filaments are
distributed more homogeneously
and especially fiber effective on
the strength.

OLD DESIGN NEW DESIGN
What’s New Comparison-Mirrors
In old design, the amount of
mirrors are 96 pieces with
4m dish diameter.
In new design, the amount
of mirrors are 150 pieces
with 5m dish diameter. (6m
with photovoltaics)
Dokuz Eylul University - Izmir TURKEY
OLD DESIGN NEW DESIGN
What’s New Comparison-Mirrors
In old design, mirrors are
bonded to grippers.This
procedure may cause the loss
of mirror because of adhesive
problem
In new design, mirrors can be
connected by using skrewed
rivet at the center and washer
at the mirror edges to the
gripper

What’s New Comparison-Cleaning System
NEW DESIGN
Dokuz Eylul University - Izmir TURKEY
OLD DESIGN NEW DESIGN
What’s New Comparison-Pipe Route
In the old system main pipe
which is connected with
exchanger passed into a mirror
because of the plate which
holds the mirror grippers.
In the new design , the plate is
removed and replaced with skrewed
rivet elements.So main pipe can
pass from the center of the dish.By
making this replacement , the
fracture of a mirror is prevented.
Dokuz Eylul University - Izmir TURKEY
OLD DESIGN NEW DESIGN
What’s New Comparison – Vertical Movement Shafts
In the old system there was
only two shaft that helps to
move dish up and down.
In the new design there is
four shafts in order to
prevent the system from
buckling caused by wind.
Dokuz Eylul University - Izmir TURKEY
OLD DESIGN NEW DESIGN
What’s New Comparison – Dish Design
In old design, the weight
of dish frame is high
because of grippers
, gripper covers etc…
In new design, frame
becomes more simple
because of changing its
design ?
Dokuz Eylul University - Izmir TURKEY
OLD DESIGN NEW DESIGN
What’s New Comparison – Mirror Grippers
In the old system these
grippers were designed as an L
beams and a supporter rod.In
addition, there was a lot of
pieces of connection parts in
order to hold mirrors.
In new design dish gripper is
constructed as some kind of
profiles and also designed
for acting as a route for
cleaning system.
Dokuz Eylul University - Izmir TURKEY
OLD DESIGN NEW DESIGN
What’s New Comparison – Dish Grippers
Old grippers were designed
as on L profile beams and a
supporter rod.
In new design, instead of L
profile; we have rectangular
profiles which has less weight
than the old one.
Dokuz Eylul University - Izmir TURKEY
OLD DESIGN NEW DESIGN
What’s New Comparison – Vertical Plane
In old design, vertical plane
has a polygon structure
obtained by connecting
profiles with interconnection
elements
In new design, in order to
provide more rigidity, close – fit
sheets are designed
Dokuz Eylul University - Izmir TURKEY
OLD DESIGN NEW DESIGN
What’s New Comparison – Horizontal Plane
In old design, vertical plane
which includes beams
obtained by connecting
profiles with interconnection
elements
In new design , in order to
provide more rigidity, close – fit
sheets are designed.In
addition, shaft at the center
provides the rotation movement
and also covers the flex pipe
and cables.
Dokuz Eylul University - Izmir TURKEY
OLD DESIGN NEW DESIGN
What’s New Comparison – Upper Tower
In old design, upper tower has
a circular shape and just like
planes, there is a weight
problem.
In new design, upper tower
has three floor and the weight
problem is solved by using
sheets in each floor.
Dokuz Eylul University - Izmir TURKEY
OLD DESIGN NEW DESIGN
What’s New Comparison – Breaking System
In the old system, clutch
disc is used due to
regulate speed
In new design, a system which
includes a circular profile, nuts
and bolts are used for
regulation of speed.
Dokuz Eylul University - Izmir TURKEY
OLD DESIGN NEW DESIGN
What’s New Comparison
In old design, lower tower
was constructed by steel that
caused a weight problem.
In new design, lower tower
constructed as an composite
which includes cement – fiber
glass.Therefore system becomes
more lighter than the old one.

Comparison With
Other Systems
1. Mirrors are flat
2. Two axis – direction exist
3. No loss efficiency because of the
distance between absorber and
mirrors (approximately 5m)
4. The deviation of solar in the
absorber doesn’t exceed 1-2 cm
5. It has vacuum which prevents heat
loss at absorber in Solarux CSP.
6. Construction site
The Advantage Of Solarux System
More efficient than parabolic and
fresnel systems
Dokuz Eylul University - Izmir TURKEY
Conclusion
• Solar flat mirror is a renewable system which based on sun light and it’s
reflection
• System can provide and store a valuable energy and use it whenever you
want.
• The electrical energy can be provided without pollution and it can be
used even at night
• This system also can be used for agricultural heating process and drying
process.
• It will contribute to the country's economy and also has the scientific
application capability, manufacturability and in addition, it can be highly
desirable in terms of sensitivity to the environment
Dokuz Eylul University - Izmir TURKEY
Conclusion
• Have good financial results, the good construction, performance, work
place or home budget, environmental cleanliness, cleanliness of the
system itself, and in many respects quite good security features and
efficiency
• The only disadvantage of Solarux CSP is the efficiency of the system
varies depending on region. Because the incident angle of the sun
coming around the world is crucial.
