The "space-based solar power" theme keeps heating up—opening a fresh growth frontier, Global X China Clean Energy (02809.HK) surges more than 3%.

NewTimeSpace News: The number of global satellite launches is growing exponentially, creating gigawatt-level demand for space-based solar power. Coupled with supply-side discipline and fresh policy tailwinds, the solar segment opened sharply higher. As of 10:27 a.m. on 23 January, Global X China Clean Energy (02809.HK) extended its rally to more than 3%; the fund has now advanced over 40% in the past six months.

Exchange data show the ETF is managed by Mirae Asset Global Investments (Hong Kong) and passively tracks the Solactive China Clean Energy Index NTR. The benchmark bundles 35 A-share clean-energy leaders with a combined market cap of roughly RMB 2.6 trillion, spanning the entire chain—solar, wind, hydro, nuclear, plus storage, inverters and grid equipment.

The index applies a dual screen: constituents must be classified by FactSet at level 6 under clean-energy sub-sectors and record average daily turnover ≥ HKD 20 million over six months; highly leveraged or heavily polluting businesses are excluded, ensuring purity and investability. The latest factsheet lists the top ten holdings—North Huachang, Yangtze Power, Sungrow, Siyuan Electric, LONGi, etc.—accounting for about 60% of the weight.

In headline news, Musk told the Davos Forum that Tesla and SpaceX will build 200 GW of solar capacity in the U.S. within three years (100 GW each) to power ground data centres and AI satellites. That figure equals twice current annual U.S. installations and is expected to catapult demand for modules, equipment and storage solutions.

CITIC Securities points out that, with no access to terrestrial grids and prohibitively costly fossil-fuel resupply, photovoltaics are the only viable long-term energy source for orbital computing platforms. Solar irradiance in space is roughly 1,367 W/m²—more than 30% above the AM1.5 standard—boosting cell efficiency, while fold-out solar arrays can be scaled flexibly to match on-board processing needs.
