About us
Drawn the way salespeople work.
Ritwerk is made by Avron Group AB in Karlskrona. The designer took shape alongside the salespeople at the group company Nordiska Energilösningar, which installs solar panels and batteries.
Why Ritwerk exists
Nordiska Energilösningar, NOEN, installs solar panels and batteries and belongs to the same group as Ritwerk. A salesperson there needs to be able to draw the roof, place the panels, check the strings and show the customer what the system will deliver, all in one tool.
That is why the designer follows the salesperson’s order: project and consumption, the roof, the panels, electrics and battery, the economics and the report. Each step builds on the one before, and every change can be undone.
The same designer is part of Avron, the group’s business system for installation companies. Ritwerk is the designer as a product in its own right, in the browser and with no account.
What we hold to
- Figures with a source: the yield from PVGIS, the loads from the regulations of Boverket (Sweden’s National Board of Housing, Building and Planning) and the Eurocode, the products from the manufacturers’ datasheets.
- Anything that could not be verified in a datasheet is marked as preliminary.
- Yield and savings are estimates and are labelled as such, in the designer and in the report.
- Projects in the no-cost designer are saved in your browser and are not sent to us.
The name
Ritwerk is pronounced "rit-verk". Rit comes from rita, Swedish for "to draw", and werk is the German word for works or factory. The drawing is the core of the tool: the outline on the aerial photo, the roof lines, the panels and the strings.

Ritwerk is provided by Avron Group AB, organisation number 559559-3996, Tennvägen 14, 371 50 Karlskrona. The designer’s interface is available in Swedish, English and German.
