JuPREMe - Lab

The Juelich Photovoltaic Research and Education Mobile Laboratory

The JuPREMe Lab is a mobile, versatile research platform for investigating the system integration of photovoltaics (PV) through direct coupling to batteries and/or other electrochemical storage systems. The platform can also be used for training and demonstration purposes.

Research

The JuPREMe Lab offers a versatile infrastructure for investigating and evaluating modern photovoltaic systems under realistic operating conditions. The focus is on research into PV systems with integrated electrical and chemical storage.

By combining PV modules with battery storage and hydrogen systems (electrolysis, storage, and reconversion), strategies for grid-supportive energy supply, efficiency improvement, and system stabilization are being developed. This allows for the investigation of holistic energy systems that enable a sustainable and flexible power supply.

Another research focus is on vehicle-integrated photovoltaics (VIPV). Here, the integration of solar cells or modules into vehicle surfaces is analyzed to increase the self-generated energy share of electric vehicles and optimize ranges and charging profiles. The JuPREMe platform enables both experimental characterization and model-based evaluation of PV performance under realistic, dynamic conditions. JuPREMe thus bridges the gap between basic research and application-oriented technology development, making a significant contribution to the energy transition and sector coupling.

Education:

The platform can also be used as a training and education program for professionals and students, as well as in schools. PV education is interdisciplinary: Theoretical content (e.g., from physics, electrical engineering) must be linked with practical knowledge (electrical circuitry, component understanding, safety aspects).

An acute shortage of skilled workers in the renewable energy sector is leading to rising system costs, even though components such as modules and batteries are becoming cheaper. In addition to training skilled workers, raising public awareness also plays a crucial role in the widespread acceptance of PV.

Experiments and components include:

• PV modules, inverters, battery storage, electrolyzer, fuel cell, variable load, GPS, and weather station

Target groups & benefits:

• Research: Collection and evaluation of real-world data on-site
• Universities / Universities of Applied Sciences: Linking theory and practical aspects in lectures and apprenticeships
• Skilled workers: Training in installation, operation, and safety aspects
• Citizens and policymakers: Awareness-raising without requiring technical knowledge
