Advanced glasses increase efficiency of solar components
PPG Industries’ (NYSE:PPG) flat glass business will exhibit its complete
line of ultra-low-iron and coated glass products for the solar industry
at booth 756 during Solar Power International 2012, Sept. 10-13, at the
Orange County Convention Center in Orlando, Fla.
PPG glass products on display will include the following:
-
SOLARPHIRE(R) PV glass provides high transmittance across the entire
solar spectrum and increased solar transmittance in the near-infrared
band. In thicknesses of 3.2 and 4.0 millimeters, Solarphire PV
glass transmits up to 91 percent of total solar energy to enhance the
performance of solar energy collection components equipped with it.
-
Solarphire AR glass features PPG’s highly durable proprietary
antireflective coating applied to one surface of a Solarphire PV
photovoltaic glass substrate. It has solar transmittance of 93.6
percent in a 3.2-millimeter thickness, offering the potential to
increase power output of crystalline-silicone modules by up to 7 watts
when it is used as a cover plate.
-
Solarphire 2XAR glass features PPG’s antireflective coating on
both sides of a Solarphire PV glass substrate. With solar
transmittance of 96.3 percent, double-coated Solarphire 2XAR
glass also enhances the efficiency of concentrated solar photovoltaic
(CSP) modules on which it is used.
-
Solarphire NaB glass is engineered for solar applications where
sodium leaching can adversely affect the performance of solar panels,
reflectors, water heaters and other devices. Formulated with a
transparent barrier coating, Solarphire NaB glass retards
the migration of sodium (Na) and other alkalis to the surface during
high-temperature processing or long-term field exposure. Temperable
and highly durable, the glass is approved for concentrating
photovoltaic (CPV) and concentrating solar power (CSP) applications
where high in-use temperatures may be encountered.
-
Solarphire HVM solar mirror glass combines a highly
transmissive, ultra-clear, low-iron float glass with a proprietary
vapor-deposited mirror coating and a lead-free protective encapsulant.
The combination of these three technologies gives Solarphire HVM
glass the ability to increase the ratio of reflected (captured) solar
energy to the incident solar energy, enabling CSP plants to generate
more power at less cost.
In addition to products, PPG will showcase its ability to
heat-strengthen glass as thin as 2 millimeters, making it strong and
flexible enough to function in a wide range of solar applications.
Visitors to the PPG booth will also see a demonstration of the company’s
proprietary roll-forming technology for real-time production of PV
module frames.
