2026-06-22

Did you know?

The bifacial power generation capability of modules

is becoming a new growth driver for power station revenue

So how is this achieved?

Let's dive into the details today


Take the high-bifaciality Tongwei TNC 3.0 module as an example

Based on a 200MW power station calculation

it can generate over one million in additional annual revenue

The improvement in bifaciality

directly leads to a significant increase in power generation

and translates directly into economic value

Compared to conventional modules

Tongwei TNC 3.0 delivers a significantly higher power output

equivalent to installing an extra batch of modules

over the same area

How does Tongwei achieve this?

First, optimize the junction box design

reduce structural shading

and let in more reflected light

Second, upgrade the cell structure

further reduce shading

and effectively enhance the rear-side "light-capturing" capability

Third, upgrade the module technology

increase the light-absorbing surface area of the module

taking "light-capturing" capability to the next level

With all three measures working together

a qualitative leap in power generation performance is achieved
