The Challenge
SolarTech Bayern, a Munich-based residential installer, was bottlenecked by their design process. Every project required a designer to manually trace roof outlines in AutoCAD, cross-reference panel specs in Excel, and build permit packages in a separate tool. A single residential design took 4 hours — and with only 3 designers, the team maxed out at 50 projects per year.
The Switch to SurgePV
In January 2025, SolarTech Bayern migrated their entire design workflow to SurgePV. The team used Clara AI to auto-detect roof geometry from satellite imagery, eliminating manual tracing. Panel placement, string sizing, and electrical SLDs were generated automatically.
The Results
By March 2026, the team had scaled to 12 designers handling 500+ projects annually — without adding a single permit coordinator. Design time per project dropped from 4 hours to 25 minutes. Permit rejection rates fell from 8% to under 1% because SurgePV's auto-generated packages include the exact documentation German municipalities require.
Key SurgePV Features Used
- 3D roof design AI with German satellite + LiDAR data
- Auto string sizing with VDE-AR-E 2100-712 compliance
- Permit-ready German documentation export (PDF + DWG)
- Net metering (EEG) financial modeling for customer proposals
