What it is

Introducing technical plans for PV installers

This new PV planning feature is a built-in tool that generates technical roof plans and string plans from your existing PV design. No exporting. No re-entering data. No manual redrawing. It uses your project data inside the Expert to create standardised documents ready to hand to the authorities and PV system installers.

1. Standardised Roof Plans

Turn your PV layout into accurate roof plans with dimension lines, annotations, legends, and a title block. Fully standardised, after the offer is signed.

2. Compliant String Plans

Visualise strings, labels, and inverter connections with clear legends and annotations for permitting and installation. It automatically calculates & includes the open-circuit voltages on string level that are required for an efficient commissioning.

3. Complete documentation packages

Export all roof and string plans into organised PDFs for installers. Use preset and consistent formats and avoid external CAD tools.
What you get

Reviews

Here's what early users think

Based on beta version testing.

"If models are handed over cleanly by Sales, then depending on the complexity of the building and project, this gives us an estimated time saving of 1–2 hours for standard residential projects."
"It is a truly excellent tool and, in terms of accuracy and usability, significantly better than the solar planner."
"I found it quite simple and intuitive. After a few minutes of trying it out, I think I understood all the functions and could have started fairly quickly with the first project."
"Very intuitive and a huge help with construction reports. Good progress and easy to use."
"Compared to SPT very easy to use and adapt changes."
"It certainly needs a little practice, but I don't feel that any features are missing at the moment. We can use it as it is, and it also saves us time and makes project planning easier."

Who it's for

Built for anyone preparing PV installation or permitting documents. Works for single‑person teams and multi‑role organisations.

✓ Technical planning

Create roof and string plans directly from your 3D layout and string design. Add dimensions, labels, and notes without switching tools or redrawing anything.

✓ Project management

Prepare clear, standardised documents for installers and authorities. Keep layouts and strings aligned so handovers stay accurate and issues on site are reduced.

✓ Back-office & all-rounders

Assemble complete roof and string plan packages without CAD tools. Use preset layouts and add any required notes or images before exporting ready‑to‑send PDFs.
