Under the spring sun in Rimini, Italy, new energy enterprises from across Europe gathered at KEY – The Energy Transition Expo 2026. During the exhibition, Tongwei and Esaving officially signed a 300MW module cooperation agreement.

At the signing ceremony, Chen Fangzhou, Head of Overseas Module Marketing at Tongwei Co., Ltd.'s Photovoltaic Commerce Department, and Luca Demattè, Chief Executive Officer of Esaving, signed the cooperation agreement on behalf of both parties. This cooperation will further expand Tongwei's business layout in the European market, accelerate the deployment and application of high-efficiency modules in the region, and provide solid product support for local clean energy development.

Cooperation between the two sides began in early 2023. From initial product exchanges to project implementation, mutual understanding has deepened over the past two years – the signing of this 300MW agreement is a natural continuation of this trust. What underpins this deepening trust is Tongwei's unceasing iterative improvement of product technology.

A true levelized cost of energy (LCOE) killer must have all-weather operational capability. Take Tongwei's newly launched TNC 3.0 high-efficiency module as an example: during early morning dew, overcast and rainy days, and dusk – periods when conventional modules start to "slack off" – TNC 3.0 modules still capture light sensitively and continue generating power. Over time, this translates to significant additional revenue over the entire lifecycle of a power station.

While providing extra value, Tongwei also offers an exceptional long-term commitment for TNC 3.0: annual linear degradation as low as 0.35%. This means that from the first day of grid connection until decommissioning 30 years later, its cumulative power generation over the entire lifecycle will create a huge "snowball effect". Lower degradation means higher lifecycle value, which is Tongwei's confidence in its quality and a solemn guarantee for every cent of customers' investment.

Esaving's repeated choice is silent recognition of Tongwei's modules. As Europe's energy transition continues to accelerate, both distributed and utility-scale power station markets are re-evaluating the long-term value of modules – it is not just about current power output, but also stable output over the coming decades. The continuation of cooperation time and again demonstrates that the performance of Tongwei modules in real projects withstands the joint test of time and the market.
