The technology firm SINN Power and the gravel and crushing plant Jais are collaborating to construct the world's inaugural floating photovoltaic system featuring vertical photovoltaic modules in Bavaria. They are receiving substantial backing from the regional agency gwt Starnberg GmbH, the Starnberg district office, and the municipality of Gilching, all of whom have collectively facilitated the progression of this distinctive project thus far.

Innovative technology

In a pioneering venture within renewable energies, the expert in tailored photovoltaic solutions, along with the esteemed gravel pit in Gilching, will actualize Germany's premier floating PV system equipped with vertically positioned and wind-resistant solar modules. This innovative technology facilitates a more effective utilization of water surfaces for electricity generation, rendering the formerly significant 15% surface sealing restriction of bodies of water virtually obsolete. Furthermore, solar power generation is highly conducive to grid integration both during morning and evening hours.

2500 “floating” modules

The initial phase of the installation, to be situated on the lake of the Gilching gravel pit, comprises approximately 2500 "Floating-SKipp" modules developed by SINN Power, currently undergoing the patenting process, arranged in an east-west orientation. The vertical alignment of these modules heralds a paradigm shift in the exploitation of artificial inland waters for solar energy production, effectively reinterpreting the existing 15% regulation.

This allows for a greater deployment of modules on lakes, enabling the installation of solar panels on smaller bodies of water. The vertical orientation not only mitigates surface sealing on the water but also facilitates efficient electricity generation throughout the day: The east-west orientation optimizes electricity production during morning and afternoon periods, when surplus generation can be particularly advantageous for grid integration. Additionally, concerns regarding snow loads are alleviated, ensuring optimal harnessing of solar energy even during winter months.

Enhances sustainable energy provision

With a planned total capacity of 1.8 MWp and an anticipated annual electricity production exceeding 1,800 megawatt-hours, the installation significantly enhances the sustainable energy provision for Jais GmbH and Co. KG. This quantity of renewable electricity equates to the consumption of approximately 725 average German households. For the Gilching gravel pit, this output translates to an expected 65% degree of self-sufficiency in electricity supply, resulting in tangible reductions in operational expenses and an additional decrease of 600 tons of CO2 emissions annually.

Commencement of installation construction is slated for August 1st, commencing with anchoring and preparatory activities along the shoreline. On-water construction is set to commence on September 1st.

The initiative not only signifies a notable progression in the utilization of renewable energy but also highlights the potential for innovative solutions to tackle regulatory obstacles and enhance energy generation from artificial inland waters. As construction moves forward, stakeholders eagerly await the fulfillment of this groundbreaking endeavor within Bavaria's sustainable energy framework.
