Solar glass mainly refers to the encapsulation or cover glass used for solar photovoltaic and solar thermal components. It uses special flower rollers to press special pyramid patterns on the lower surface of ultra-white glass, and special velvet dough on the upper surface to increase the internal reflection effect, reduce directional reflection of the glass, and promote sunlight absorption.

Through special pattern design and anti-reflection technology, the directional reflection of the glass is minimized, the internal reflection effect is increased, the glass absorbs solar energy more effectively, and the heat collection efficiency is maximized.
