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™.

Spectrum Calculation Program

Pilkington Spectrum is a Windows-based glass performance model which enables you to quickly and efficiently calculate key properties of insulating glass units without the need to construct and measure them. 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.
  • Ultra violet (uv) transmittance and colour rendering index (Ra).
  • Other properties (e.g. pendulum body impact resistance, fire resistance, resistance to manual attack, etc.).
