As the seasons change, bringing severe cold, snow, and weak light, photovoltaic power stations face a silent test. Gokin GBC modules, with industry-leading performance, deliver on the full-dimensional promise—from safety and reliability to power generation and returns.
How is Reliability Demonstrated?
Reliability cannot remain a mere paper promise—it must be proven through rigorous validation.
Gokin GBC modules have passed advanced industry tests, including:
55mm hail impact test
Enhanced DH3000/TC600 aging test
Dynamic mechanical load test up to 1500Pa (equivalent to withstanding strong typhoons)
Wind tunnel test
They have also been awarded dual IEC 61215 and IEC 61730 certifications by TüV Rheinland.
These tests simulate extreme challenges that modules may encounter throughout their entire lifecycle. This means that whether facing winter hail, heavy snow in the north, or strong winds in high-altitude regions, Gokin GBC modules demonstrate exceptional robustness and durability.
How is Efficiency Measured?
Winter brings weaker light intensity and a higher proportion of scattered light—posing a true test of a module’s photoelectric conversion capability.
Gokin GBC utilizes back-contact cell technology, which eliminates front-side gridline shading, allowing the cells to receive light across nearly 100% of their surface area.
This structural advantage enables Gokin GBC to capture and convert low-intensity scattered winter light with significantly higher efficiency than conventional modules.
While traditional modules may "shut down early" due to insufficient light, Gokin GBC continues to deliver substantial power output, effectively extending daily power generation hours.
Even in the season with the shortest daylight, Gokin GBC ensures higher energy yields.
How is Return on Investment Ensured?
Winter dust and snow are key factors leading to "hidden losses" in power generation.
Gokin GBC modules feature an anti-dust accumulation frame design that effectively reduces the impact of dust and snow coverage. On average, this helps power stations reduce cleaning and maintenance frequency by at least three times per year.
This not only directly lowers operational labor and costs but also increases the station’s annual power generation by over 5% by maintaining cleaner module surfaces.
The beginning of winter marks a time of accumulation and challenge.
Gokin GBC modules—with their proven reliability, high-efficiency core, and dust-shedding intelligence—empower power station value throughout winter and across their full lifecycle.
