What to Upload at M2

For Lease projects, the M2 design package should generally include:

  • Production Model
  • Shading Report
  • Plan Set / Line Diagram

Make sure the uploaded files clearly show the required design information and are final versions for the project.


When Updated As-Built Plans Are Required

Updated as-built plans are required when there are major changes to the installed system, such as:

  • Changes to module count
  • Changes to module wattage
  • Changes to module / inverter / battery manufacturer or model
  • Modules moved to a different roof plane
  • Modules moved to a new roof structure

When Updated As-Built Plans Are Usually NOT Required

Updated as-built plans are usually not required for minor changes such as:

  • Racking-only changes
  • Module movement within the same roof plane
  • Electrical routing or BOS-only changes
  • Other minor installation adjustments

Important: Some state-specific rules may still require updated plans.


Common Mistakes to Avoid

To avoid M2 delays or rejected documents:

  • Do not upload only the proposal if the required design package is missing
  • Make sure the Production Model is included
  • Make sure the Shading Report is included
  • Confirm the Plan Set / Line Diagram is final
  • Review whether project changes are major or minor before submitting
