Eturnity: cost, fit and limits
Eturnity is a solar design platform made by Eturnity AG that combines a 3D site modeller built on imagery, LiDAR or drone data with a System Designer that places modules, simulates shading and checks strings, and produces roof plans, string plans and single-line diagrams.
What to know first
Eturnity publishes no prices on the pages opened; the homepage offers a free trial of unstated length. The product is organized around one model: a 3D site built from satellite imagery, orthophotos, LiDAR or drone data, from which the System Designer produces roof plans, string plans and single-line diagrams. The homepage says the company embraces AI and innovation but names no AI feature.

Who Eturnity is best for
Installers who want drawings from one model
Roof plans, string plans and single-line diagrams are generated from the same model, so a design change flows to every drawing.
Teams sizing inverters and batteries
The System Designer sizes inverters, batteries and strings with layout optimisation, which suits projects where storage affects the string design.
Companies that survey by several methods
The 3D modeller accepts satellite imagery, orthophotos, LiDAR or drone data, so a company with mixed survey methods can model every site in one tool.

What Eturnity does
- 3D site modeller
- The modeller builds a site from satellite imagery, orthophotos, LiDAR or drone data, so the roof geometry can start from whichever source a project has.
- System Designer
- The System Designer places modules and simulates shading, which gives a layout with an estimate of production lost to obstructions such as chimneys, neighboring buildings and trees.
- Automatic string compliance checks
- Strings are checked automatically for compliance inside the System Designer, which catches wiring mistakes before drawings are issued, though the pages opened do not say which standards the checks follow.
- Plans from one model
- Roof plans, string plans and single-line diagrams come from the same model, so documents stay consistent when the layout changes and a designer does not redraw each sheet by hand after an edit.
- Sizing and optimisation
- Inverters, batteries and strings are sized with layout optimisation, so a design can be reworked to fit different equipment or a battery addition without starting the layout from scratch.
How Eturnity handles your data
The imprint page was opened, but it describes the company rather than its data practices. The pages opened do not state whether customer data trains models, how long it is retained, where it is hosted, or whether any security certification applies. Eturnity AG is named as the maker. A buyer that must document data location, for example under European data protection rules, should request the privacy policy and a data processing agreement from the vendor before starting the free trial.
Where Eturnity falls short in practice
- No public pricing. Neither the trial button nor any pricing page states a price, so a buyer cannot compare Eturnity's cost with the tools that publish figures, and a purchase decision waits on a sales conversation.
- AI is not specified. The homepage says the company embraces AI and innovation but names no AI feature, so roof detection or layout automation by AI cannot be confirmed.
- Integrations page missing. The integrations page returned a 404 and no company names appear on the homepage, so CRM, financing or monitoring connections are unverified and should be asked about directly.

Alternatives to Eturnity
Eturnity: common questions
Does Eturnity have a free trial?
Yes, the homepage shows a Start free trial button, but it does not state the trial length or limits. Whether the trial includes the System Designer and all plan outputs is not described, so ask Eturnity before relying on it to evaluate a full workflow.
What drawings can Eturnity generate?
The homepage says roof plans, string plans and single-line diagrams are generated from the same model. Strings are checked for compliance automatically in the System Designer. The pages opened do not say which standards the checks follow, so confirm that against your own jurisdiction.
Which site data sources does Eturnity accept?
The 3D site modeller is described as built on satellite imagery, orthophotos, LiDAR or drone data. The pages opened do not name the imagery providers, so coverage in your region should be checked during the trial, particularly for rural sites.
Does Eturnity use AI?
The homepage says the company embraces AI and innovation but names no specific AI feature. Automatic string compliance checks and layout optimisation are listed without being called AI. A buyer who needs AI roof detection should ask for a demonstration.
Who makes Eturnity?
The imprint page names Eturnity AG, and the headquarters country is given as Switzerland on the vendor's pages. The pages opened do not describe hosting, retention or data practices, so ask for the privacy policy and a data processing agreement before uploading customer project data.
