4 FAQs about Wentian New Energy Solar Power Generation

Why are solar wings installed at the tail of the Wentian module?

The solar wings are installed at the tail of the Wentian module to avoid being blocked by each other at certain angles from the sun and to maximize the power generation efficiency . The flexible solar wings are used for lighter weight and higher power compared to traditional rigid solar wings.

How big is Wentian's solar wing?

Wentian's solar wing is two times larger than that of the core module Tianhe. Only four of such solar wings can generate 80 percent of the power for the combination of the core module and two lab modules. There are wrist-like units designed to help rotate Wentian's two 27-meter-long wings by 360 degrees to face the sunlight in unblocked positions.

How big are Wentian solar panels?

Apart from its extra large size, Wentian has a set of extraordinarily-long wings - flexible solar panels with double degrees of freedom. The full wingspan is over 55 meters, longer than half a soccer field, setting a new record for solar panels used for China's spacecraft.

How big is Wentian's solar array?

The total area of the solar array will reach as large as 400 square meters when three main modules including the core module and the two lab modules are assembled. Wentian's solar wing is two times larger than that of the core module Tianhe.
