Light and shadow

Kubuqi

China's seventh-largest desert, once known as the "Sea of Death"

60% of it consists of shifting sand dunes, reaching up to sixty meters in height

The desert environment is ever-changing

Here, the diurnal temperature difference tears at the surface

An average of 25-35 days of strong winds each year bring sandstorms

It is a harsh test of life

But now, a green revolution is quietly taking place here

In the southern part of the Kubuqi Desert in Inner Mongolia

a "blue ocean" carrying the dream of clean energy

Is emerging from the sands

The 1,000,000 kW photovoltaic pilot project (Phase II)

Extreme challenges require extraordinary "equipment"

The project adopts Tongwei TNC-G12 700W+ high-power modules

totaling 1,700,000 pieces

844MW

The conversion efficiency is 23%, specifically designed for large ground power stations

Facing the challenges of the desert and gobi

it builds the foundation for efficient power generation

Excellent attenuation characteristics

better temperature coefficient

and higher reliability

First-year attenuation

1%

Second-year attenuation

0.4%

Temperature coefficient

-0.28%

The TNC-G12 module adopts a low-voltage solution with 66 cells

The single-string power is increased by 30% compared to the conventional 585W module

This reduces the total string quantity by approximately 30% across the plant

Costs for brackets, cables, and labor are significantly reduced

Ultimately, it can help reduce the system cost of the power station by

about RMB 0.0848/watt

(*Calculated based on 710W modules compared to 585W modules)

The dual-glass bifacial design

not only fully utilizes the abundant sunlight in the desert

amplifying the gain on the back

its high-power characteristics also greatly increase land utilization

further enhancing the project's economic value

The mode of power generation on the panels and planting underneath

is quietly changing the desert's ecology

The shade cast by the modules provides shelter for fragile life

It promotes the restoration and growth of desert vegetation

The towering "PV forest" effectively reduces surface wind speed

minimizing wind erosion and soil loss

silently guarding this vulnerable land

Protection requires intelligent enhancement

In terms of the TNC-G12 modules used in the project

the glass front is covered with a hydrophilic coating

endowing self-cleaning capabilities

After the wind and sand, rain and dew can take away the dust, significantly reducing dust adhesion

lowering long-term maintenance costs

making clean energy stewardship more sustainable

According to statistics

each installed module equals the ecological contribution of planting 110 trees

Nearly 1.7 million modules

converge into a vast sea of energy

equivalent to planting 190 million trees of hope for this land

From the "Sea of Death" to the "Sea of Hope"

TNC modules

in the new energy base in the southern part of the Kubuqi Desert

use the power of light

to realize the modern legend of desert gushing spring water
