Guardian Adds EcoGuard® to Solar Glass Line
Guardian Industries in Auburn Hills, Mich., continues to build its line of solar glass products with the introduction of two new low-iron float glasses designed to maximize solar energy transmission.

EcoGuard® float glass is a solar energy solution for concentrating solar power mirrors, photovoltaic (PV) energy systems, concentrating PV systems and solar thermal applications. It offers optimal energy and light transmission, is easy to process and is available in a variety of glass thicknesses ranging from 0.95- to 12-mm. The new glass also is available in several transmission ranges to meet the needs of a variety of applications.

EcoGuard pattern glass can be used in a variety of applications, including PV energy systems, solar thermal collectors, greenhouses and other applications requiring high solar transmission and light control. It offers advantages in manufacturing and performance due to the its pattern uniformity and solar transmission consistency. The glass also is IEC-validated and tested and certified by the SPF Solartechnic Institute. The company currently is producing matte/matte and matte/prismatic pattern glasses, and is conducting research to further increase solar transmission by optimizing the textured pattern.


SAF Provides Product for Renewable Energy Projects
Atlanta-based Southern Aluminum Finishing Co. Inc. (SAF) has announced that it now has available aluminum extrusions, sheet and services for designers, installers and manufacturers of renewable energy equipment and support structures. 

According to a REN21 Renewables Global Status Report released this spring, most sectors of the renewable energy market have increased by double digits despite a global economic crisis.


Solarlux Puts Fenzi Group to Work for the Environment
FENZI SpA in Tribiano (Milano), Italy, has created not only a new Solar Coatings division dedicated to developing innovative technologies for solar energy, but also a new complete line of paints for solar mirrors: Solarlux.

Designed to make the most out of new technologies for solar thermal plants, the company reports that its new line of paints meets the highest durability and resistance standards. The paints provide long-term protection for solar mirrors that are located primarily in desert areas, and constantly exposed to corrosion by sand, wind, temperature fluctuations and salt aggression. The Solarlux paints feature chemical resistance to corrosion and UV radiation, top performance under thermal and environmental stress and abrasion resistance.

Solarlux paints have been designed and produced to meet a wide variety of needs, with different chemical compositions and application methods, and can thus be used in all solar thermal plant systems: parabolic mirrors, disk systems, tower systems, etc. In fact, these paints are produced in different versions: for copper and copper-free mirrors; in lead-free or low-lead versions; and for different application systems, including two-coat (base + top) or three-coat (base + intermediate + top).


PPG Introduces Solarphire PV and AR
Solarphire AR (anti-reflective) glass from Pittsburgh-based PPG Industries was engineered to maximize solar energy transmission to solar-collecting photovoltaic (PV) cells. Solarphire AR glass is formulated with a proprietary anti-reflective coating that facilitates the efficient conversion of solar light into energy. In 3.2-millimeter thicknesses, Solarphire AR glass yields a solar-weighted transmittance of more than 93 percent.

The company also has introduced Solarphire PV glass to maximize solar energy transmission for PV modules. Because of its clarity, Solarphire PV glass delivers enhanced transmittance in the ultraviolet/visible portion of the solar spectrum, between 350 and 1,100 nanometers, where crystalline PV cells are most responsive to the sunís energy. This clarity is the result of a proprietary glass formulation that, the company says, allows Solarphire PV glass to transmit more solar energy than competitive products, which increases the energy efficiency of solar cells.
