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.

Programa de Cálculo Spectrum

O Pilkington Spectrum é um modelo de desempenho de vidros baseado em Windows que permite calcular, de forma rápida e eficiente, as principais propriedades de unidades de vidro isolante (UVI), sem a necessidade de fabricá-las e realizar medições. O Pilkington Spectrum pode ser utilizado para fornecer as seguintes informações:

  • Propriedades ópticas e solares (transmitância, refletância, absortância, fator solar g, entre outras).
  • Valor Ug do vidro central.
  • Valores de isolamento acústico.
  • Transmitância ultravioleta (UV) e índice de reprodução de cor (Ra).
  • Outras propriedades (por exemplo, resistência ao impacto de corpo pendular, resistência ao fogo, resistência a ataques manuais, entre outras).
