Solar PV Design Software Features

01.

Geolocated 3D Design

Locate your project on satellite maps and create a complete 3D model. Draw buildings, rooftops, and obstacles to simulate shading and optimize solar panel distribution in your photovoltaic installation.

03.

Automatic Electrical Configuration

Generate the complete electrical design for your solar installation: string configuration, inverter selection, cable sizing, and professional single-line diagram ready to present.

02.

International Standard Ballast Calculation

Landatu PV Designer calculates the required ballast for your photovoltaic installation complying with worldwide regulations (Eurocode, ASCE, etc.) and automatically adapting to any wind zone.

04.

Professional Technical Documentation

Export all necessary documentation for your photovoltaic project: PDF load certificate, complete Bill of Materials (BOM), single-line diagram, installation layout, and energy production simulation.
