FAQS 4
Why do solar panels have a high transmittance?
Lower iron content impurities result in higher solar transmittance. For the most commonly used 3.2mm and 4mm thick glass in domestic applications, the visible light transmittance for solar radiation generally reaches 90% to 92%. As one of the most crucial components of solar installations, photovoltaic glass demands high transparency.
What is solar transmittance?
Solar transmittance is defined as the ratio of solar radiation perpendicularly incident on window glass that is transmitted through the glass and calculated according to a formula specified in JIS R 3106 Testing method on transmittance, reflectance and emittance of flat glasses and evaluation of solar heat gain coefficient.
Which material has the highest spectral transmittance of solar radiation?
This study analyse spectral transmission of solar radiation of glass and plastics. The 8 h transmittances are higher than at 12 h and are higher in winter than summer. Methacrylate and smoked glass have the highest transmittance in UV, VIS and NIR ranges. Polycarbonate has the lowest transmittance in UV, VIS and NIR ranges.
What is visible light transmittance?
Visible Light Transmittance (Tv, %) is the percentage of incident light in the wavelength range of 380 nm to 780 nm that is transmitted by the glass. Visible Light Outdoors/Indoors (Re out/in, %) is the percentage of incident solar energy directly reflected by the glass.
