Specific values vary depending on the type of glass and its application, but generally, solar glass aims for high light transmission, low iron content for minimal color distortion, and sufficient strength to withstand environmental conditions. . Visible light transmittance (VLT) is a percentage of the visible portion of the solar energy spectrum coming through the glass. It is expressed as a figure between 0 (no light) and 100 (all light). Colour. . Solar glass is a key component used in photovoltaic (PV) modules – typically as a front cover to protect the solar cells while allowing maximum light transmission. Understanding this spectrum is crucial because it determines how glass transmits, reflects, or absorbs light across various wavelengths.
