- Peer-to-Peer (vZEV): The legal framework for virtual self-consumption communities (vZEV) now enables you to share your surplus solar energy with neighbours at near-retail rates, creating additional revenue streams and fostering local energy communities. This is a game-changer for solar installation in multi-owner buildings.
From Permit to Plugged-In: Navigating Grid Connection
Once your contract for solar panel installation is signed, the next crucial step is ensuring your sun-generated electricity can seamlessly flow onto the local network, whether it’s CKW or ewl. While this process involves several stages, an experienced installer simplifies the journey.
- Pre-Check (2–5 days): Your installer submits a detailed site plan, proposed tilt, and power rating of your solar installation to the grid operator to verify transformer capacity and ensure network compatibility.
- Technical Application (1–2 weeks): This involves the submission of the mandatory TAG (Technical Connection Agreement) form. All inverters must meet the stringent IEC 62116 anti-islanding standards. Any solar installation exceeding 50 kW will typically trigger a more comprehensive network study.
- Installation (1–4 weeks): This is the physical phase where solar panels are mounted, cabling is routed, and the essential smart meter installation is scheduled by the grid operator.
- Commissioning (1 day): The final step involves a utility engineer flicking the switch, officially connecting your solar installation to the grid and uploading its system ID to Pronovo for subsidy processing.
From the initial handshake with your installer to the moment your system starts feeding electricity into the grid, expect the entire process to take between 4–12 weeks—often faster than many Swiss kitchen renovations.
Installer Insight: “Proactive planning is key. Order smart meters early in the process, as in summer, ewl’s installation calendar tends to fill up faster than the streets during a Luzerner Fasnacht parade,” advises Pascal Huber, a seasoned project manager at Solar Sense GmbH, highlighting a common bottleneck in solar installation.
