50. Conclusion
The Advantage Of Solarux System
1.
2.
3.
4.
5.
6.
Mirrors are flat
 More efficient than parabolic and
Two axis – direction exist
fresnel systems
No loss efficiency because of the
distance between absorber and
mirrors (approximately 5m)
The deviation of solar in the
absorber doesn’t exceed 1-2 cm
It has vacuum which prevents heat
loss at absorber in Solarux CSP.
Construction site
Dokuz Eylul University - Izmir TURKEY

51. 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

52. 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.
