L22 AR Querschnitt


Up to 10% more solar yield with sunarc® anti-reflection glass!

The special nano structure of the inner and outer surface of sunarc® anti-reflection glass reduces reflection considerably, raising the 91% transmission rate of normal solar glass to 96%. The improvement is especially effective with the slanted irradiation that often occurs during winter months.
