About this calculator
This calculator identifies the cell format used in a PV module based on its physical dimensions and cell layout. Enter the module width, height, and the number of cell columns and rows — the calculator will estimate the individual cell size and match it against a catalog of standard formats, from full-size wafers (M0 through G12) to half-cut, third-cut, and quarter-cut variants.
All four input parameters are available in PAN files, making this calculator a practical way to determine the likely cell format or verify cell type from physical measurements when it is not explicitly stated in the file.
