Simplify your planning process.

It’s not only the installation process that is made easy through the MSP mounting system and Solrif photovoltaic in-roof system – the planning process also practically takes care of itself, thanks to the web-based planning software Solar.Pro.Tool from Schweizer, or SPT for short.

All you need to do is enter the required building parameters using the 3D design tool. In next to no time, SPT from Schweizer calculates all the information needed to design the system best suited to a particular project. The documentation includes all the static calculations, parts lists, layouts and instructions you need to ensure a fast and safe installation.
