photovoltaic (PV) industry is booming, with installed capacity growing at a double-digit rate year over year. As PV systems become more widespread\u2014from residential rooftops to utility-scale solar farms\u2014ensuring the safety and reliability of every component is critical. Among these components, the DC Surge Protection Device (DC SPD) plays an irreplaceable role. It diverts transient overvoltages caused by lightning, grid switching, or inductive loads, protecting sensitive PV equipment such as inverters, combiner boxes, and solar panels from irreversible damage. However, DC SPD failure is a common issue that plagues many PV projects. It leads to equipment burnout, system downtime, reduced power generation, and even fire hazards.
