Chasing the Dream of Deep Blue! Tongwei High-Efficiency Modules Empower Offshore PV to "Brave Winds and Waves"
2025-08-20

In recent years

the rapid economic growth of eastern coastal provinces

has led to a continuous increase in electricity consumption

To alleviate the pressure on power supply and land use

offshore photovoltaics have emerged as a viable solution

With a coastline stretching 18,000 kilometers, the Chinese mainland

presents vast potential for photovoltaic installations

making offshore photovoltaic development a promising prospect


However, the marine environment is characterized by its volatility

Photovoltaic modules will face the rigorous challenges of extreme climates

including high ultraviolet radiation, high humidity and heat

high salt spray, wave impact, and typhoons

Tongwei TNC modules are specifically designed for

the differentiated reliability requirements of the offshore photovoltaics' environment

They undergo stringent testing for load, salt spray, composite aging

and PID (Potential Induced Degradation) resistance

The module degradation results are all below industry standard requirements


The reliability of Tongwei's offshore photovoltaic products

has been recognized with the "Deep Blue Ocean" certificate

from CPVT & Huaneng Clean Energy Research Institute

the ASTM E1597 certificate from UL Solutions

and the salt spray level 8 certificate from TÜV NORD

Tongwei's newly launched TNC 2.0 modules

incorporate a special aluminum frame

effectively addressing the corrosive effects of high salt spray environments

By enhancing frame strength, corrosion resistance

abrasion resistance, and electrical insulation performance

the modules ensure

structural stability in the marine environment

Leveraging the 908 technology (Tongwei's independently developed 0BB technology)

steel screen printing, TPE technology

and Poly Tech

the TNC 2.0 modules not only offer high reliability

but also improve overall power generation performance

Compared to conventional TOPCon modules in the market

the TNC 2.0 modules achieve a comprehensive power generation gain of over 0.67%

(data sourced from internal Tongwei calculations)

Offshore photovoltaics

represent not only an expansion of energy sources

but also a symbiosis with the ecosystem

Tongwei TNC 2.0 modules

will collaborate with more partners

to chasing the dream of deep blue, embracing the ocean

and composing a new chapter in the development of clean energy
