In the context of Building-Integrated PV (BIPV), it’s possible that not all modules generate the same amount of power, voltage, or current due to partial shading, reflections, and variations in dimensions or orientation. To maximize energy production under these conditions, EnergyVille is developing customized electronic solutions adaptable to specific situations. New module and converter technologies enabling efficient energy generation in non-uniform and dynamic conditions must be collectively optimized. Therefore, we explore converters related to our research on DC and micro-/nanogrids.
One of the most innovative yet challenging solutions is based on the idea of changing the electrical connection between PV cells in real-time while the PV module adapts to its environment. We propose a Reconfigurable Smart PV (RSPV) module concept that significantly enhances energy generation in non-optimal conditions. This module integrates switches and intramodule converters to enable self-reconfiguration.
Both for standard and reconfigurable modules, converters must be compact and meet stringent reliability requirements. This necessitates reliability testing and an understanding of potential failures beyond current standards and measurements. We aim not only to measure the failure rate but also to understand the degradation rates of such new converter designs. For this purpose, we use accelerated synthetic mission profiles.
