Sustainable energy for
the water industry

The energy transition does not stop at sensitive areas such as sewage treatment plants and water protection zones. Until now, photovoltaic systems were hardly feasible in these areas, especially in areas around pumping stations, for reasons of drinking water protection. Thanks to our innovative SKipp technology, we can now offer you tailor-made solutions that meet the strict requirements in water protection zones II and III and at the same time generate renewable energy.

In addition, our floating PV system SLake offers an effective way to efficiently use water surfaces at sewage treatment plants. This conserves valuable land resources and enables sensible dual use through sustainable electricity production. In view of the EU's new municipal wastewater directive, which stipulates mandatory energy neutrality, our systems are the ideal solution for future-oriented and environmentally conscious energy supply.

SLake: The advantages at a glance

Modular and scalable design:

We can design the system in such a way that the individual module blocks can be moved on the pond for professional pond de-silting.

Less water evaporation:

The partially covered water surface is exposed to less sunlight, which means the water heats up less.

Creation of new habitats: The floating elements provide protection and breeding areas for water birds.

Higher efficiency:

Due to the cooling effect of the water, the PV modules achieve a higher yield compared to land-based PV systems.

SLake

The use of existing water surfaces at sewage treatment plants conserves valuable land resources and enables sensible dual use with additional power generation. Especially in view of the municipal wastewater directive recently adopted by the EU Parliament - with requirements for mandatory energy neutrality - the floating PV system SLake is a sensible solution.

Approval procedure : Our technology has been proven to be approvable, so that purification ponds and treatment ponds can be fully used for the operation of floating photovoltaic systems - regardless of the otherwise usual requirements for artificial bodies of water under the Water Resources Act.

Focus on nature conservation: Breeding platforms with access aids can be installed on each of the module blocks so that water birds can nest there and find protection from predators. The distance between the platform and the water surface is at least 50 cm so that water birds can swim under the facility. The entire facility was designed with environmental and nature conservation aspects in mind (e.g. use of drinking water-friendly materials).

Pilot plant on the polishing ponds of the Ammersee sewage treatment plant in Eching: This is where the world's first floating photovoltaic system on polishing ponds is being built. Bavaria's Energy Minister Hubert Aiwanger gave the starting signal for this lighthouse project as part of the Bavarian Energy Days 2024 and launched the first of around 50 module blocks.
SINN Power accompanied the project throughout the planning and approval phase and is also responsible for all procurement issues as well as the construction and grid connection.
As a technology and general contractor, we also create holistic energy concepts for your company. We can draw on an extensive product portfolio of various photovoltaic applications

SKipp Land: The advantages at a glance

No piling required:

Because the modules can be deflected under wind loads, anchoring in the ground and thus penetrating the ground zone is not necessary. The integrated reset weight ensures that the modules cannot tip over.

Drinking water protection:

By using only drinking water-friendly materials, we prevent harmful substances from penetrating the soil.

Supply of pumping systems:

The operation of pumps can be adapted to the hours of sunshine so that a high degree of self-sufficiency can be achieved.

High power yield:

Our long-term measurements show that vertically positioned PV modules achieve a higher yield than conventional south-facing systems.
