The “nemesis” of loose photovoltaic connector nuts—ratchet anti-loosening mechanism
As a key component of the new‑energy sector, the photovoltaic (PV) industry has experienced rapid growth worldwide in recent years. Driven by global low‑carbon initiatives, supportive national policies, and advances in corporate technology, China’s new‑energy industry has achieved remarkable results on the international stage. Nevertheless, the reliability of PV systems continues to face numerous challenges. Connector failures remain one of the most critical safety concerns in PV installations. According to industry research reports, connector‑related faults account for as much as 38% of all failures in PV power plants, with approximately 30% of these attributable to loose connections or poor contact.
