Comparisons
Compare the tools side by side.
Each comparison sets the designer against a tool that PV installers use in Sweden, Germany, Spain or Italy. Everything about the other tools comes from the vendors’ own pages.

How we chose the tools
The selection is based on the tools that appear in job adverts, training programmes, distributors’ courses and the trade press in Sweden, Germany, Spain and Italy in autumn 2026. Some are used mostly for houses and smaller commercial roofs, others for large systems and energy studies.
Each page says what the tool is built for, when it suits the job better than the designer and when the designer suits it better.
How to read the tables
The details on the other tools come from the vendor’s product page, pricing page, help centre, documentation or press releases. Where a detail could not be verified there, the table says "Not stated". That means we have not found it, not that the feature is missing.
Prices are given as the vendor states them, in their currency and with or without VAT as they write it. The Ritwerk column describes only what the designer does today. If you see something that has changed, write to info@ritwerk.se.
Questions and answers
Questions and answers
Who wrote the comparisons?
Avron Group AB, which makes Ritwerk. That is why the other tools are described only with details from the vendors’ own pages, with a source and date, and the Ritwerk column describes only what the designer does today.
What does "Not stated" mean?
That the detail could not be verified on the vendor’s own public pages when we checked them. The feature may exist all the same. Ask the vendor if that particular point matters to you.
How often are the details checked?
The date on each page shows when the details were last checked. Vendors change their pages and prices, so check with the vendor before you decide.
