PPG to exhibit high-performance solar glasses at Solar Power International

Advanced glasses increase efficiency of solar components

PITTSBURGH, Sept. 7, 2012 – 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.
