YOUR FREE PLANNING SOFTWARE

THE SCHLETTER CONFIGURATOR.

For over a decade, our Configurator has been one of the most popular and versatile planning tools for solar systems. 

It enables you to make professional plans and accurate calculations for your roof installations—and, best of all, it’s completely free. 

The Schletter Configurator 3.0 is our best version yet, as it’s fully optimized and adjusted to your specific needs. It calculates faster, looks and feels better, and even allows you to plan several roof systems simultaneously.

FEATURES

Plan directly in Google Maps.

  • Roof surfaces can be marked out and planned directly using the Google Maps interface.
  • Once the roof inclination has been input, the system calculates the exact size of the roof surface to be covered and, if required, suggests the optimum configuration depending on orientation.

AUTOMATICALLY DETERMINE WIND AND SNOW LOADS.

  • When the post code or name of the town is entered, the regional standard loads for wind and snow are automatically factored in.
  • This applies worldwide, as the Schletter Configurator incorporates the world’s most extensive load determination database.
A detailed interactive map showing terrain categories, load parameters, and various marked geographical locations. Tabs on the left side are labeled Project, Location, Terrain, and Load areas.

PLAN SEVERAL ROOFS IN PARALLEL.

  • Several roofs and roof systems can be processed within one plan. This makes it much simpler, because the location parameters such as terrain category, relevant standard loads etc. only need to be detected by the system or input once.
  • It is therefore possible to configure different roof types with different mounting systems and orientations in one plan.

Get started quickly or use the professional mode.

  • In fast configuration mode, the system suggests the configuration that is best, based on size, alignment, and structural loading.
  • In professional mode, users can select the individual parameters manually.

EXPORT THE PLANS TO AUTOCAD OR OTHER PLANNING TOOLS.

  • It is also possible to export the plans as DXF files, which means that they can be linked to the standard planning programs used by architects, structural engineers, and planners.
  • The program generates a structural analysis and verifiable documentation for all plans it produces. The parts lists can be edited manually.
