Converters at Module Level
In Building-Integrated Photovoltaics (BIPV), PV modules do not always generate the same amount of power, voltage or current. Partial shading, reflections, and differences in module dimensions or orientation can all affect performance.
To maximise energy production under these conditions, EnergyVille develops customised electronic solutions that can adapt to specific operating environments.
Smart Converters for Maximum Energy Yield
Efficient energy generation in non-uniform and dynamic conditions requires the joint optimisation of module and converter technologies.
That is why we investigate advanced converter concepts as part of our broader research on DC systems and micro- and nanogrids.
One of the most innovative, yet challenging, approaches involves dynamically changing the electrical connections between PV cells. In this concept, the PV module continuously adapts to its environment in real time.
Reconfigurable Smart PV Modules
To enable this functionality, we are developing a Reconfigurable Smart PV (RSPV) module concept.
These modules integrate switches and intramodule converters that allow the electrical configuration of the module to adjust automatically to changing conditions. As a result, energy generation can be significantly improved under non-optimal operating conditions.
Reliability as a Key Requirement
Whether applied in standard or reconfigurable modules, converters must be compact, efficient and highly reliable.
To achieve this, we conduct extensive reliability testing and investigate failure mechanisms that go beyond current standards and conventional measurement approaches.
Understanding Degradation and Lifetime
Our objective is not only to measure failure rates but also to understand how new converter designs degrade over time.
For this purpose, we use accelerated synthetic mission profiles that simulate long-term operating conditions. These tests help us identify degradation mechanisms and improve the reliability and lifetime of future converter technologies.
