LPM oder planarisierte Daten für für PV*SOL?

PVLPM or planarized data for PV*SOL?

Airteam offers over 15 different planning data formats – including planning data for PV*SOL.

Unlike other partner software, there are two planning formats that can be imported here.

This blog post discusses the differences between Airteam’s LPM (Low Poly Model) and PV*SOL file (planarized model).

Due to faster data delivery, LPM data is particularly popular among Airteam’s customers. Thanks to the included surroundings, shading analyses can also be carried out in PV*SOL.

The only limitation is the project size. As soon as the building footprint exceeds 1,000 m², we advise against using Low Poly Models (LPM).

Why Airteam does not recommend LPM for larger roofs (from 1,000 m²)

PVSOL is solar planning software that allows the import of a 3D model in OBJ format (geometry based on a certain number of vertices) that was previously created in other software. PVSOL supports the import of OBJ files with up to 500,000 vertices.

For large projects, the number of vertices must be reduced to make the geometry compatible with PV*SOL. If the same 500,000 vertices are used on a significantly larger and more detailed roof, the resolution of the 3D model is considerably reduced, and smaller objects may no longer be visible.

For this reason, we do not recommend using the LPM file for projects larger than 1,000 m².

The planarized PV*SOL file contains an exact geometric simplification of the roof, with the number of vertices significantly reduced. Therefore, this is a very good solution for projects larger than 1,000 m².

Let’s take a 5,000 m² project as an example:
Although an LPM file can be generated, the model quality is significantly reduced, as can be seen in the images.

Which solutions do we offer our customers who need PV*SOL for projects larger than 1,000 m²?

• We offer a simplified model of the project (roof only) with better resolution and optimized geometry, including predefined mounting areas for solar panels.

• Solar planning can also be done in our Airteam Fast Fusion 3D model.

If model quality is of minor importance, a 3D model can, of course, still be generated. This is merely a recommendation from Airteam.
