Typhoons Bavi?&?Baihaitun Make Landfall | CGC Jiaxing and Sanmen Verification Bases Face the Test; Modules from Trina?Solar, Tongwei and Other Brands Pass Harsh Field Challenges
From July to August?2026, coastal Zhejiang was hit by a rare double?typhoon strike. Typhoon?Bavi (Category?13 at its centre) and Typhoon?Baihaitun (Category?14 at its centre) made successive direct landfalls, posing severe challenges to the safe operation of coastal PV power plants. During this period, CGC’s Jiaxing Outdoor PV Verification Base and Sanmen Off?shore Verification Base in Zhejiang leveraged their monitoring and data?acquisition systems to fully record the real?world performance of PV modules from participating manufacturers under actual typhoon conditions. Post?typhoon on?site inspections confirmed that all module arrays under test remained intact with continuous normal power?generation data, having successfully passed this real?world extreme?weather ordeal.
Notably, these encouraging results were obtained in one of China’s harshest natural test?beds for typhoon resilience. Zhejiang accounts for roughly 10?% of all typhoon landfalls across China, of which as many as 80?% are “first?impact typhoons” that strike without being weakened by mountain ranges. Severe and super?typhoons occur frequently, bringing high intensity and destructive power. CGC’s two bases are precisely located along this exposed coastal front?line. Their unique geographic location makes them natural, excellent test platforms for evaluating the wind?resistance performance of PV modules. Every typhoon event acts as a rigorous, real?world field assessment. CGC continuously delivers high?value empirical reliability data for the PV industry.
Jiaxing Base: Facing Category?14 gales from Typhoon?Baihaitun; Comprehensive Validation of Multiple Bracket Types and Installation Configurations
At 17:30 on?9?August?2026, powerful Typhoon?Baihaitun (Category?14, sustained wind speed?42?m/s) made landfall at Yuhuan, Taizhou, before striking northern Zhejiang in a secondary landfall, placing the Jiaxing Base within the typhoon’s core impact zone. The base monitoring system ran non?stop, logging wind?and?rain data minute?by?minute. After the typhoon subsided, CGC technical teams carried out thorough on?site inspections of participating modules and confirmed all units remained undamaged.
- Module appearance and structure: No frame deformation, no glass breakage and no back?sheet damage.
- Fasteners and mounting structures: Bolt torque values remained normal; aluminium clamps and reinforced mounting points showed no loosening. Both fixed mounting brackets and horizontal single?axis trackers sustained zero structural damage.
- Power?generation performance: All arrays maintained normal generation readings throughout the typhoon with no abnormal performance degradation.
Situated in the typhoon?prone Yangtze River Delta, the CGC Jiaxing Verification Base is routinely exposed to wind and rain hazards. It hosts fixed brackets and horizontal single?axis trackers alongside three typical fastening solutions: bolted connections, aluminium clamping blocks and reinforced mounting points. A full suite of meteorological sensors records irradiance, spectral data, temperature?humidity, wind speed?direction, rainfall and soiling rate, with data sampled at least once per minute. Closely replicating real?world power?plant operating conditions, the facility thoroughly evaluates wind?resistance and structural reliability for diverse module formats and installation schemes.
Sanmen Base: Withstanding Direct Impact of Typhoon?Bavi in Tidal?flat Conditions of High Salt?fog and High Tide Levels
Earlier, Typhoon?Bavi came ashore along the Taizhou coast at 23:20 on?11?July?2026, placing CGC Sanmen Off?shore Verification Base squarely within the typhoon’s direct path. During the event, high tidal levels combined with violent wind?waves to create extremely harsh operating conditions. PV?module arrays from participating manufacturers delivered stable performance under these extreme loads.
Post?typhoon checks verified intact modules, zero structural damage to mounting structures, no loosened fasteners and full recovery of normal power?generation metrics.
As a professional tidal?flat offshore PV verification platform in China, the Sanmen Base sits within a tropical monsoon zone with annual precipitation of 1700?mm and persistently high salt?fog and humidity levels. One of its core missions is to test typhoon?resistance and long?term weathering performance for offshore PV modules. The real?world Bavi event has yielded precious first?hand field data on the environmental adaptability of offshore PV products.
With Extreme Weather Becoming More Frequent, Empirical Field Data is the Litmus?test for Product Reliability
Driven by global climate change, extreme?weather events such as typhoons are growing more frequent. PV power plants are setting higher requirements for module wind?resistant design, bracket strength, fastening schemes and overall structural stability. CGC’s two verification bases have successfully weathered this successive double?typhoon challenge. Real?world field data not only validates the robust quality of products under test, but also demonstrates the core value of third?party verification bases: instead of relying purely on laboratory simulation, performance is proven under genuine outdoor conditions.
At present, modules from more than ten manufacturers are undergoing testing at the Jiaxing and Sanmen bases, covering diverse module formats, encapsulation technologies, tilt angles and bracket?matching solutions. CGC warmly invites additional suppliers of PV modules, materials, mounting structures and related components to join its verification programme. Leveraging genuine extreme?weather conditions across the Yangtze River Delta and coastal tidal flats, partners can generate robust real?world evidence for product reliability.
Let data speak and facts prevail. CGC Verification Bases help PV products stand firm against wind, rain and the test of time.
