Metrology, Simulation and Prediction of PV Energy Yield
Achieving optimal energy yield is essential for solar energy systems. While the performance of PV modules is typically measured indoors under standardized test conditions, real-world operating conditions often differ significantly.
To bridge the gap between laboratory measurements and outdoor performance, EnergyVille combines advanced indoor and outdoor testing facilities with accurate energy yield simulation models.
Accurate Measurements in the Lab and the Field
Our metrology techniques provide highly accurate energy measurements under a wide range of conditions.
We combine these measurements with meteorological data and advanced data analysis techniques. This allows us to accurately interpret the relationships between environmental conditions and PV system performance.
As a result, we gain a deeper understanding of how solar technologies perform in real-life applications.
Advanced Energy Yield Simulations
Our energy yield simulation model is scenario-based and uses historical weather data to predict the daily energy yield of solar cells and PV modules under varying weather and light conditions.
The model combines optical, thermal and electrical parameters to provide detailed insight into thermal variations within solar modules. By accounting for these effects, it delivers significantly greater accuracy than many commercially available energy yield estimation tools.
Evaluating New PV Technologies and Challenging Applications
The simulation model is particularly well suited for assessing the performance of emerging PV technologies and installations operating under complex conditions.
Examples include:
-
Bifacial PV systems
-
Floating PV installations
-
Agri-PV applications
-
Building-integrated photovoltaics (BIPV)
-
Tracker-based PV systems
-
Installations on uneven terrain
This allows us to accurately evaluate the energy yield potential of innovative PV technologies before large-scale deployment.
Integrating PV into Buildings and Energy Systems
In addition, we are developing a modelling environment for integrating PV into building façades. The model considers both thermal and electrical performance, as well as their interactions.
We also simulate highly variable PV generation in combination with battery storage, load management and grid conditions. This enables us to optimise system configurations for a wide range of applications.
Our goal is to maximise self-sufficiency and self-consumption while improving overall system performance.
Connecting PV, Storage and Grid Integration
This integrated approach links research on PV generation with the development of battery systems, energy management solutions and grid integration strategies.
By combining these domains, we support the design of smarter, more efficient and future-proof energy systems.
