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.
SCM 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

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.
