PV modules

as the core of solar power generation systems

have their reliability directly impacting

the system's performance and lifespan

With the continuous advancement of PV technology

the market's quality requirements for PV modules

are increasing

making it increasingly important

to conduct PV module reliability tests

In areas with high temperatures and humidity year-round

PV modules are highly susceptible to

internal corrosion due to damp heat

leading to performance degradation

Therefore

conducting rigorous damp heat tests

has become a crucial step before modules enter the market

Tongwei PV modules' damp heat tests

simulate the harsh environment of outdoor high temperatures and humidity

placing the modules in a test chamber at 85°C

and 85% relative humidity

for up to 2,000 hours

This is equivalent to making the modules

"operate" in the severe environment of high-temperature steaming

and water vapor erosion for nearly three months

Tongwei's newly launched TNC 2.0 modules

feature a tightly coated front surface

for long-term weather resistance

and a physical anti-seepage "armor" on the back

effectively reducing water vapor penetration

Through rigorous damp heat testing

the internal circuits and solar cells of the TNC 2.0 modules

are comprehensively protected

maintaining stable performance

Tongwei TNC 2.0 modules

operate stably for extended periods in high-temperature and high-humidity areas

continuously providing clean energy to users

building a solid foundation for high-efficiency PV with their superior quality
