    Schematic representation of the work packages in the »DeepTrack« project.

    How should PV trackers optimally track? This question is being researched in the project »DeepTrack« together with PV Zimmermann Tracker GmbH. In DeepTrack, the latest AI and power plant simulation methods are applied to maximize the yield of complex power plants, such as Agri-PV power plants. The methods are implemented and investigated in a pilot plant at the solar test field in Merdingen. | Duration: 03/2023 - 02/2025

    Agrivoltaic system from hop farmer Josef Wimmer and AgrarEnergie GmbH in Hallertau.

    Hops are grown on a large scale in the Hallertau region: Almost a third of the hops produced worldwide are grown on around 17,200 hectares of Hallertau hop gardens. As a crop that remains in the same location for several years, hops are particularly exposed to climatic influences. Dry periods in July and August sometimes led to significant yield losses: in the particularly affected years of 2013, 2015 and 2018, yields were up to 40 % lower, depending on the hop variety. This is where the "HoPVen" project comes in, in which the world's first agri-PV system in hop growing is being scientifically investigated. The dual use of the land for both agriculture and energy generation through photovoltaics can increase resilience to the consequences of climate change and diversify the income streams of farms. | Duration: 11/2023 - 10/2026

    Planned location of the battery storage system with fast charging station at the ISE site "Haidhaus".

    Lithium-ion batteries used as energy storage are a key element of the energy transition. This type of battery is being used in ever greater numbers, especially in electromobility. At the end of their life in the vehicle, the batteries can continue to be used in stationary storage before being recycled. Even though this significantly minimizes the CO2 footprint and makes the recycling economy more effective, many new questions arise, e.g. about the qualification of the cells, cooling and the integration of stationary storage into the infrastructure. These issues are being investigated in detail in the ecoLEPuS project. | Duration: 09/2022 - 05/2026
