Detailed profile including pictures, certification details and manufacturer PDF . M1, M2, M3, M4, M5, M6, and M12 are standard different wafer sizes used in the solar cell production process Why is Wafer Size Matter? The demand for wafers has exponentially increased over the past two decades due to the increase in the production and sale of PV systems, smartphones and more. The. . In order to increase the power of solar panels and reduce the cost of solar panels, the silicon wafer industry has been driven to continuously expand the size of silicon wafers, from M2, M4, G1, M6, M10, and finally to M12 (G12) and M10+. Before year 2010, monocrystalline silicon wafers were. . In 2024, the photovoltaic industry needed to celebrate the fifth anniversary of the M12 (210x210mm) large-size modules. From the release of the first M12 (210x210mm) module by Trina Solar in 2020 to December 2024, the cumulative shipment of M12 modules is expected to reach 380GW, of which Trina. .
