Photovoltaic Layout

DescriptionThis Excel VBA application is designed for solar panel layout (calepinage) on rooftops or ground surfaces. The user works on a simple row/column grid representing the installation area and places photovoltaic modules according to the project constraints. The tool then generates a configuration string that encodes the full arrangement.

Key features:
  • Visual placement of solar panels within a grid.
  • Save, reload, and reuse complete layouts.
  • Automatic subdivision into rectangular sub-groups of modules, each defined by origin coordinates and dimensions.
  • Export as a reusable layout_chain variable for electrical design, project documentation, or simulations.
  • Fully integrated in Excel, no external CAD or specialized software required.
