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 "stack effect (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 eli...

Following the grand conclusion of the SNEC PV Power Expo 2026 in Shanghai, the technical and sales teams of Xiamen Art Sign Co., Ltd. conducted a comprehensive study onsite. Our goal was to investigate the latest global solar infrastructure trends and translate these frontline insights into better, cost-effective engineering solutions for our global clients. 1.Fixed Racking vs. Tracking Systems: A Rational Return to Lifespan Stability While Solar Trackers have been a mature technology in the market for years, their commercial adoption remains a careful trade-off. True, they can boost power generation by 15% to 25% under perfect desert or flat plain conditions. However, as plants mature, global developers are increasingly facing the hidden costs of trackers: high vulnerability to complex terrains and escalating long-term Operation & Maintenance (O&M) expenses driven by motorized moving parts and drive shafts. This explains the continuous, strong global demand for heavy-duty Fixed SolarPV Mounting Structures With zero moving parts, zero mechanical O&M costs,and absolute stability against violent wind and heavy snow, fixed racking remains the most predictable, trouble-free bedrock for a 25-year solar investment. 2.Material Evolution: Why Zn-Al-Mg Steel is Utilised in Solar Racking For non-aluminum structural applications, the industry increasingly utilises Zinc-Aluminum-Magnesium solar racking instead of traditional Hot-Dip Galvanized(HDG) Steel Historically, heavy-duty outdoor infrastructure—such as prefabricated substationcabins and electrical enclosures—relied heavily on Stainless Steel for ultimate corrosion resistance or Hot-Dip Galvanized Steel for structural strength. However, stainless steel often proves cost-prohibitive for large-scale deployments, while traditional HDG steel is prone to rusting at post-processing cut edges and weld seams.To balance performance and budget, modern electrical engineeringand grid infrastructure have widely shifted toward Zinc-Aluminum-Magnesium (Zn-Al-Mg) steel as a premium, cost-effective upgrade. According to metallurgical data, Zn-Al-Mg offers 10x to 20x higher corrosion resistance than traditional HDG steel. More importantly, it features an automatic "Self-Healing" effect. When the steel is cut, drilled, or scratched during onsite installation, the Magnesium (Mg) and Aluminum (Al) elements in the coating dissolve slightly and migrate to form a highly dense protective chemical layer over the exposed edge. This process protects the cut-edges without requiring slow, costly manual touch-up painting onsite. 3.Practical Applications: Where This System Shines Different sites need different setups. We supply Ground And Roof Solar Mounting System solutions using Zn-Al-Mg steel to handle these tricky environments： （1）Near the Coast: High salinity and damp ocean air will rust normal steel fast. Our upgraded coating stops this salt damage completely, so it's perfect for rooftop projects near the sea. ...
