The race for space solar is on as satellite demand opens a high-value market
The space sector is seeing increased investment in solar power technology as satellite demand grows. Companies are moving toward lighter, cheaper, and more durable solar solutions to power the expanding orbital economy.
Why it matters
Advancements in space-based solar power are essential for the long-term viability of the growing satellite industry, which supports critical global infrastructure like weather forecasting and internet access.
Money is pouring into the space sector in general as well.
Spacecraft have relied on sunlight for electricity for decades. As satellite launches accelerate, that established power source is also becoming a rapidly expanding business niche.
Professional accounting firm PwC expects the space economy to reach $2 trillion by 2040, according to pv magazine . That outlook is increasing interest in solar panels for orbit that are lighter, cheaper, and more durable.
One sign of the sector's momentum came from the 2026 conference circuit. Space solar drew added attention at three U.S. events cited by pv magazine : the Space Power Workshop in Torrance, the Space Photovoltaics Research and Technology Conference in Cleveland, and the Small Satellite Conference in Salt Lake City. Established aerospace suppliers and newer solar companies had large presences there.
