Recently, Tongwei officially signed a cooperation framework agreement with Japan-based GBP Co., Ltd. The two parties will conduct in-depth communication and cooperation focusing on the Japanese market and explore diverse application scenarios of high-efficiency photovoltaic products in the region.
Yohei Tatsukawa, Chief Executive Officer of GBP Co., Ltd., and Xue Qingsong, Vice President of Marketing at Tongwei Co., Ltd., attended and witnessed the signing ceremony. Masato Ikari, International Sales Department Manager of GBP Co., Ltd., and Xiong Cheng, Head of Asia Pacific for Module Marketing in PV Business Department of Tongwei Co., Ltd., signed the agreement on behalf of both parties.

As a local enterprise deeply rooted in the Japanese market, GBP Co., Ltd. has long been serving the Japanese photovoltaic industry and adheres to strict standards for product stability and long-term performance. Through this commitment, the company has accumulated rich market experience and customer resources. With in-depth understanding of user demands, policy trends and industry rules in the Japanese market, GBP looks forward to promoting Tongwei's high-performance modules to the market in a more localized manner. The establishment of this framework cooperation marks the beginning of complementary advantages between the two parties and lays a foundation for further collaboration in the Japanese market in the future.

Case Study: Japanese Project Using Tongwei Modules
In Japan, available spaces for power generation systems are found in residential areas, factories, warehouses, and even scattered plots in cities. Given the limited land availability, every module needs to continuously and stably generate more electricity within a restricted area. Additionally, climatic factors such as typhoons, strong winds and snowfall expose modules to more extreme conditions during operation. Beyond efficiency itself, the key question is whether photovoltaic modules can operate stably over the long term and consistently deliver the expected power generation capacity.
Tongwei TNC 3.0 provides a scenario-specific solution tailored to Japan's actual conditions. At the system level, the increased module power of TNC 3.0 reduces the requirement for supporting components such as brackets and cables for the entire system, cutting overall investment costs by approximately 1.74%*. For users, this means lower capital investment and faster achievement of higher power generation returns. (*Calculated based on a 1MW color steel tile roof project in Tokyo, Japan)

Meanwhile, the flexible buffer layer design adopted by TNC 3.0 significantly reduces the risk of module cracking. Even if cracking occurs, the application of quarter-cut technology reduces the affected area to 50% of the original size. This helps avoid significant power drop during extreme weather conditions such as heavy snow and strong winds, ensuring continuous and stable operation of the system over the long term.
Generating more electricity within limited space and maintaining higher stability during long-term operation to deliver consistent returns – this is the shared goal pursued by Tongwei and GBP Co., Ltd. in Japan. Through continuous technological iteration and precise scenario adaptation, both parties are bringing the vision of "high quality, more power generation" into real life.
