China-based DAS Solar has outlined a set of measures to mitigate hot spots in PV modules, which occur due to shading or irregular current flow and can lead to overheating, efficiency loss, or failure. The company employs half-cell design to reduce resistive heating and limit temperature rise by over 25 %. Intelligent circuits with bypass diodes reroute current around shaded areas to prevent heat accumulation. Self-cleaning frame structures reduce dust and debris buildup, lowering shading risks. High-temperature-resistant encapsulants with dual-glass construction improve thermal durability. Infrared welding enhances soldering precision and minimizes micro-cracks, supported by 100 % electroluminescence inspection for defect detection. Additionally, DBC cell technology divides cells into thousands of micro units, allowing uninterrupted generation even when sections are shaded.
