Product Detail

Shanghai Mac Corporation is a leading Low‑Iron Solar Glass manufacturer and supplier.

Low‑Iron solar glass is a special glass material with low ferric oxide content, Fe₂O₃ content ≤150 ppm. It is available in thickness from 2.0 mm to 4.0 mm and maximum dimension up to 2200×3200 mm, with plain or anti‑reflection coated surface options. It delivers high light transmittance above 91.5%. This product is mainly applied for photovoltaic modules and BIPV projects. It reduces light loss caused by iron impurities, allows more sunlight to reach solar cells, and improves overall power generation efficiency of solar systems.
