SOLAR COLLECTOR MIRROR:

The Solar Collector Mirror (SCM) is a light weight composite metallic mirror with high total solar reflectance is invented, designed, developed and patented in U.S.A and Worldwide by Mr. Khurram K. Nawab and Mr. Rashid Ali of Green Energy Systems, Inc. (GES). SCM is a result of pioneering research in the metal composite technology with a special innovative and patented coating. GES brings this innovation to CSP, CPV and BMPV (Smart Mirror™ PV) systems that are superior to the conventional glass mirrors technology being currently used which is heavy, expensive and highly breakable.

The other patents of Khurram K. Nawab and Rashid Ali, in the field of clean energy are:

• • Solar Collecotor Mirror
• • Receiver Tube "Helios"
• • Smart PV System™.
• • Solar Hydro electric Power system.
• • PBB Green power system.

SOLAR RECEIVER TUBE & SWIVEL JOINTS

CONVENTIONAL GLASS MIRROR SYSTEM		GES 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.

ROTATION & TRACKING SYSTEM

Archimedes said “ Give me lever and a place to stand and I will move the world ”
Green Energy uses the Archemedes lever principle that anything that can be moved from above will need less torque.

OTHER KEY ADVANTAGES

COLLECTOR EFFICIENCY – GES RENEWABLE ENERGY VS STANDARD TROUGH

The ray-tracing program GES 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 GES Renewable Energy Smart Trough and a standard trough, showing GES Renewable Energy is less sensitive to tracking errors than standard troughs.

DEGREES OFF CENTER ( DOC ) GES ( % ) STANDARD TROUGH ( % ) 0 81.2 81.1 0.5 81.2 80.2 0.7 80.2 76.2 0.8 75.1 59.2 1 64.5 29 1.2 53 0 1.5 38.4 0

MAINTENANCE AND CLEANING

• Regular and constant velocity • Adjustable water pressure & flow rate • Mechanical Cleaning with Rotation brush • Water recycling ( Recovery Filtration and Reuse) • Drying with high flow rate of air • Remote Radio controlled panel • CCTV cameras • Ability to work in adverse conditions • Low water consumption • Cleaning of the top and bottom of the parabola same time • Simultaneous cleaning of receiver tube • Elimination of Swivel joints greatly reduces the complexity of Maintenance operations and breakdown time.
