NGA has published an updated Glass Technical Paper (GTP), FB39-25 Glass Properties Pertaining to Photovoltaic Applications, which is available for free download in the NGA Store.
The growing demand for renewable energy has placed solar technology at the forefront of global energy solutions. Solar glass, a critical component in photovoltaic (PV) panels, depends on the superior optical and mechanical properties provided by high-purity silica sand.
Silica sand for solar glass manufacturing plays a direct role in determining the optical properties of the final product: Transmittance: Solar glass requires >91% light transmission in the visible and near-infrared spectra. Low Haze Levels: Achieved through the purity and proper processing of silica sand.

What type of glass is used for solar panels?
Semiconductor-grade glass. Specialty coatings. Silica sand is a critical raw material for producing the high-performance solar glass essential to photovoltaic and solar thermal technologies. Its purity, particle size, and low impurity content are paramount in achieving the optical, thermal, and mechanical properties required for solar panels.
Why is silica a good material for solar glass?
Thermal Stability: High silica content provides resistance to thermal shock, ensuring glass stability in varying environmental conditions. Hardness and Durability: Solar glass must withstand external impacts (e.g., hailstones) and endure prolonged UV exposure. Silica's inherent hardness (Mohs scale: 7) is critical for these properties. 4.
