Why choose our solar PV design tools

Easy 3D Modeling

No need to spend extra time or money on expensive 3D drawing or programs. Our software generates 3D models of buildings automatically using data from Google Maps, imagery or Plex-Earth.

Fast & Efficient

Our PV design software speeds up the entire engineering process and saves you more than 75% on engineering time and cost. We remove repetitive and time-consuming tasks by automating calculations, layouts and reports.


Automatic configurations (design phase) and augmented reality (construction phase) will prevent wrong installations. Our photovoltaic software generates solar panels, calculations and bill or materials without any design errors.

One Platform

One platform to design it all. All the tools you need are available in one place and we offer integrations to 3rd parties.

Support Team

Our incredible team provides tutorials, trainings, demonstrations and 1:1 support if needed.
