G1 vs. M10 Solar Cells – What Do They Mean for Panel Performance?

Title - G1 vs. M10 Solar Cells – What Do They Mean for Panel Performance? When it comes to solar panel manufacturers and solar panel providers in India , technical specifications often become marketing jargon. Among these, "G1" and "M10" solar cells are frequently touted, but what do they actually mean for performance? G1 cells typically refer to 166 × 166 mm half-cut PERC (Passivated Emitter and Rear Cell) solar cells. They’re a modern standard, used widely by leading panel makers. On the other hand, M10 cells are slightly larger in size, i.e., 182 × 182 mm. Because they’re larger, panels made of M10 cells require fewer cells overall and reduced inter-cell wiring, which leads to improved electrical efficiency. Key Performance Factors Each cell type supports high-efficiency values; G1 cells have 21-22%, while M10 cells offer a slightly higher value. Furthermore, power outputs vary on the panel; typical G1 panel power ratings range from 430 to 450 W, while ...
