PV systems Bollpark South Vechigen
Recently, the last part of the PV systems on the new housing estate Bollpark Süd in Vechigen near Bern.
We were allowed to realise the project from plan on behalf of Aventron plan and award contracts and supervise the execution through to final acceptance.
There were a few challenges that required special attention:
- Five individual, angled roof shapes with different dimensions
- Various roof structures (ventilation structures, skylights, fall protection system, etc.)
- High roof edge
- Inverter installation on the roof
- Combination with green roofs
We are delighted to have successfully mastered these challenges and installed a total of over 400 modules with a total output of over 150 kW on five roofs.p to have placed. We did this without the use of performance optimisers.
This project illustrates that comprehensive planning pays off in more complex projects.
- Client PV systems: Aventron
- Realisation: PonzioSolar
- General contractor: Losinger Marazzi
"It was a challenging project with many project participants, which required a great deal of coordination. Energie21 GmbH closely supervised the realisation, so that we as clients only had to be involved in important matters and had far fewer pending issues than usual during the acceptance process. We were very impressed by the high level of professionalism, expertise and pleasant cooperation with Energie21."
