Procedure to calculate your roof:

  • Please fulfill all fields,
  • Base on the calculated results (right hand side),
  • Adapt the number of columns of your roof to the recommanded columns,
  • Adapt the number of rows of your roof to the recommanded rows,
  • Check that the indication "Your PV generator is optimised!" appears in the dimension of your PV generator's casket,
  • Change the panel orientation and follow the procedure in order to have the different performance of your PV generator.

Use of the building

Is the installation for a building classified as ERP (building receiving public)?

Specific recommendation

Is this installation needs specific recommendation due to the outside climatic atmosphere of the building?

If yes, thank you for specifying the distance to the sea, the wind zone, snow zone, etc.:

If you are using the MV3i Solution
