  ALUBOND U.S.A SOLAR COLLECTOR MIRROR - LIGHT-WEIGHT METALLIC MIRROR  
 

The Alubond Solar Collector Mirror ( ASCM ) is a light weight composite metallic mirror with high total solar reflectance is invented, designed, developed in U.S.A by Mulk Enpar R.E’s Khurram Khan Nawab and patented in U.S.A and Worldwide. ASCM is a result of pioneering research in metal composite technology with a special innovative and patented coating. American Building Technologies Inc (ABTI) brings this innovation to CSP, CPV and BMPV (Booster Mirror PV) systems that are superior to the conventional glass mirrors technology being currently used which is heavy, expensive and highly breakable.

Khurram Khan Nawabs other patents in the filed of green energy are:
  • Alubond PV Booster Mirror.
  • Receiver Tube ' Helios"
  • Solar PV Plat Form.
  • Solar Hydro electric Power system.
  • PBB Green power system.
   
ASCM Advantages:
 
  • Highly durable exterior grade core.
  • Features phenomenal flatness
  • Low maintenance.
  • Mirror - Hydrophilic Principle (Self Cleaning Property)
  • Easier handling, packaging and shipping
  • Concentration full range UV, visible, NIR and IR (380 µm to 2400 µm)
  • Light weight
  • Retains its shape
  • Mirror are mass produced
  • Unbreakable Mirrors

  MULK ENPAR RENEWABLE ENERGY KEY ADVANTAGES  
     
 
CONVENTIONAL MIRROR SYSTEM   MULK ENPAR RENEWABLE ENERGY SYSTEM
REFLECTOR PANEL HEAVY MIRRORS - 10 KG / M2 REFLECTOR PANEL LIGHT METAL MIRRORS – 3 KG / M2
   
Difficult to retain parabolic shape
 
Requires extensive support frame
 
 
 
 
 
   
ASCM retains reflectivity (90-95%) and parabolic shape over a period of 20 years
   
Simple substrucutre support frame required
   
Savings of 200% in weight, substrantial savings in cost and higher efficiency

SOLAR RECEIVER TUBE & SWIVEL JOINTS

  
     
 
CONVENTIONAL MIRROR SYSTEM   MULK ENPAR RENEWABLE ENERGY SYSTEM
SOLAR RECEIVER TUBE MOVING WITH SWIVEL JOINTS SOLAR RECEIVER TUBE FIXED WITHOUT SWIVEL JOINTS
SWIVEL JOINTS TWO FOR EVERY TROUGH SWIVEL JOINTS NOT NEEDED
   
Solar receiver tube placed high
 
Entire trough including the solar receiver is rotated using complex hydraulics.
 
This requires thousands of expensive swivel joints which require high maintenance.
 
   
Solar receiver tube is fixed at the bed of the concave
   
A row of 9 troughs can be moved using a small motor of 0.33 HP / 246 Watts
   
System is capable of reaching temperatures over 400°c and a steam pressure of over 60 bar.

TRACKS FROM BELOW USING HYDRAULICS & HEAVY MOTORS USES ARCHIMEDES PRINCIPLE.
LARGE MOTOR REQUIRED TO MOVE STANDARD TROUGHS. SUB ARRAY OF 9 TROUGHS MOVED USING A SMALL MOTOR.
 
     
  Archimedes said “ Give me lever and a place to stand and I will move the world ”  
  Mulk Enpar R.E uses the Archemedes lever principle that anything that can be moved from above will need less torque.

  COLLECTOR EFFICIENCY - MULK ENPAR RENEWABLE ENERGY VS STANDARD TROUGH  
     
 
The ray-tracing program Mulk Renewable Energyp.exe calculates the trajectories of the sun’s rays and the radiated rays from all the surfaces in the collector. The table above gives collector efficiency between Mulk Renewable Energy Trough and a standard trough, showing Mulk Renewable Energy is less sensitive to tracking errors than standard troughs.
