Belgium, the Netherlands, and Germany have reached record-high power prices due to the current heat wave in Europe and its implications, with market intelligence provider Montel reporting that Belgium set an all-time record of €1,038.25/MWh for the 15-minute slot starting at 8:45 p.m. This grid crisis exposes a brutal paradox: while soaring temperatures drive air conditioning demand to its peak, extreme heat simultaneously degrades solar panel efficiency. What challenges does this situation pose for solar racking supplier? The current energy crunch stems from a fundamental flaw in solar infrastructure:photovoltaic panels are notoriously heat-sensitive, suffering from severe thermal degradation as temperatures soar. This physical limitation creates a dangerous mismatch in the power grid. According to Montel, the sharpest price spikes occurred during the evening peak—right when solar generation rapidly faded with the sunset, yet cooling demand remained dangerously high. Data shows Germany’s residual load jumped to 51.5 GW, leaving a 10.4 GW deficit above typical levels. Without sunlight and with overheated equipment, the grid was forced to rely on expensive, inefficient fallback generation. To mitigate thermal degradation, the role of photovoltaic mounting structures is evolving from mere mechanical support to active heat management. Innovative fixed-mount manufacturers are redesigning TUV certified solar brackets to maximize natural ventilation. By optimizing tilt angles and increasing ground or roof clearance, these new structures trigger a "chimney effect"—allowing passive airflow to sweep underneath the modules and significantly lower panel temperatures. Consequently, when designing solar mounting systems for the European market, companies should consider not only structural stability but also effective panel heat dissipation. Whether for rooftop or ground-mounted applications, mounting systems should feature optimized tilt angles and adequate clearance from the roof or ground to promote natural airflow and ventilation. In addition to meeting wind and snow load requirements, thermal management should be integrated into the design process, enabling sales teams to provide more tailored and technically sound solutions for European customers. For example, when designing ground-mounted and rooftop solar projects, Artsign considers the clearance between the mounting system and the ground or roof surface a key design parameter. To improve heat dissipation during periods of extreme heat, we recommend using taller Solar L-feet mountingfor metal or pitched roofs to increase airflow. For flat roofs, C steel structures or mounting systems with steeper tilt angles—such as triangular kits, adjustable legs, or front-and-rear leg assemblies—provide better ventilation and enhanced cooling performance. Furthermore, to address the critical evening power deficit highlighted by Montel, fixed structures are being optimized for bifacial modules. By eliminating backsi...
