SINN Power Launches Innovative Floating PV Plant in Bavaria

SINN Power has inaugurated a next-generation floating solar photovoltaic (PV) installation in Bavaria. The newly commissioned plant delivers an installed capacity of 1.87 MW and an estimated annual output of 2 GWh, while covering only 4.65 percent of the lake’s surface area.

A second phase of 1.7 MW is planned, which will keep total lake usage under 10 percent further reinforcing efficient land and water utilisation.

During its initial operation, the installation achieved nearly 60 percent reduction in grid electricity consumption, with the company expecting this figure to reach 70 percent as operations stabilise. 

Engineering and Technology

At the heart of the project lies SINN Power’s patented SKipp system, which introduces a vertical east-west module orientation separated by open water corridors measuring at least four meters wide. 

This configuration ensures balanced energy production throughout the day and improved generation during low-light hours in the morning and evening.

The system’s substructure, extending up to 1.6 meters beneath the water surface, provides structural stability and flexibility. It enables the floating arrays to adapt to varying wind conditions and water levels while maintaining optimal alignment. Energy generated from the system is transmitted through a floating grid connection cable to a shore-based feed-in point.

The project was developed under the patronage of Hubert Aiwanger, Deputy Minister-President and Minister of State for Economic Affairs, Regional Development and Energy. 

Future Prospects and Applications

The SKipp technology is suited for artificial water bodies deeper than 1.6 meters, such as quarry lakes and gravel pits. Its design caters to high-consumption industrial and commercial users, offering a grid-friendly production profile that enhances regional grid stability.

SINN Power plans to expand this vertical floating PV concept to open-water locations, combining scalability with sustainable energy generation at sea.

The initiative follows the company’s 2023 proposal to develop a floating solar project in Eching am Ammersee, underscoring Germany’s growing expertise in floating solar energy systems.
