ENTECH, based in Keller,
Texas is a subsidiary of WorldWater & Solar Technologies.
ENTECH builds and distributes turnkey, fully installed
solar systems for its customers using advanced, patented
concentrator photovoltaic or “CPV” solar
technology for a variety of commercial and utility
scale applications.
Originally developed for use in space, the exclusive
design of ENTECH’s curved acrylic Fresnel lenses
captures sunlight and focuses it onto small solar
cells, making it ideal for commercial solar use.
This development has resulted in greatly reduced
electricity costs compared to conventional flat-plate
solar technology. The performance and reliability
of ENTECH’s CPV technology is proven and has
been demonstrated by the
U.S. Department of Energy for over 10 years – setting
ENTECH apart from other manufacturers as the only
CPV manufacturer with an extensive track record of
proven reliability, with no degradation.
Advantages:
- Years of Proven CPV Operating History
- Extremely Low Cost Per Watt Installed
- Most Reliable CPV Available on the Market
- Third Party Verified
- No Silicon Shortage Issues - Uses only 5%
the Amount of Silicon Needed for Conventional
Systems

How Does ENTECH’s
Advanced Solar Technology Work?
ENTECH’s uniquely
designed photovoltaic or “PV” concentrator
cell is a modified version of the crystalline silicon
cell that is used in flat plate PV panels. The major
difference is that the metalized grid on the concentrator
cell’s surface conducts 20 times more electrical
current. As a result, the cell has a larger metalized
conductive grid, and ENTECH’s optically clear
prismatic cell cover is bonded to the cell to refract
incoming light away from the grid onto the silicon.
The system employs two axis tracking modules and
is mounted in a supporting frame. The support structure
is made from readily available structural galvanized
steel materials.
Unbeatable
Competitive and Cost Advantages
The selling price of ENTECH competes directly or
beats all solar PV competitors including manufacturers
of flat panel, crystalline, poly crystalline, ribbon
or thin film – whether it is installed for
distributed generation or for central power plants,
anywhere in the world. ENTECH can deliver the last
kWh (and BTU) over the last mile of an energy transmission
at a lower cost than conventional fuel based power
plants. In addition, unlike other solar technologies,
ENTECH’s technology can deliver both electricity
and heat (cooling) competitive to retail energy prices.
ENTECH issued 13 patents to protect its state-of-the-art
solar technologies and established more than 15 world
records in conversion of sunlight to electricity.
Several more patent applications are planned for
2008.
