Pilkington Optiwhite™ for Solar Applications
Pilkington Optiwhite™ is a range of extra clear low-iron float glass products with very high solar transmittance, offering improved solar energy conversion and consistent performances. This range of low-iron glass products is suitable for use in thin film photovoltaics, crystalline silicon photovoltaics, concentrated solar power technology, solar thermal collectors and solar mirrors.
The Pilkington Optiwhite™ Range includes the standard and well established low-iron glass Pilkington Optiwhite™ and Pilkington Optiwhite™ S, which was developed specifically for the solar industry and offers even greater solar energy transmittance. Pilkington Microwhite™ is our Pilkington Optiwhite™ in its extremely thin version (glass thicknesses down to 1.0 mm).
With its very high solar energy transmittance, our low iron glass Pilkington Optiwhite™ is the ideal cover plate for a range of solar technologies, including Thin Film Photovoltaics, Concentrated Solar Power Technology and Solar Thermal Collectors. Pilkington Optiwhite™ can also be used as a cover plate for Crystalline Silicon Photovoltaics.
Features & Benefits
- Very high light and solar heat transmittance.
- Consistent lifetime performance following prolonged exposure to the sun (no solarisation).
- Available in annealed or tempered/toughened form for Pilkington Optiwhite™ and Pilkington Optiwhite™ S; available in annealed form only for Pilkington Microwhite™.

Pilkington Spectrum is a Windows-based glass performance model which enables you to quickly and efficiently calculate key properties of a wide range of single glazing and insulating glass units. Also available as an app for mobile devices, you can use Pilkington Spectrum to provide the following information:
- Light and solar properties (transmittance, reflectance, absorptance, g value, etc.).
- Centre pane Ug-value.
- Sound insulation values.
- Global Warming Potential (GWP), or carbon footprint.
- Ultra violet (uv) transmittance and colour rendering index (Ra).
- Other properties (e.g. pendulum body impact resistance, fire resistance, resistance to manual attack, etc.).
