The Sun Never Sets in Space
For decades, space-based solar power has lived in the realm of science fiction and ambitious research papers. The idea is elegant: place solar panels in orbit where sunlight is constant — no clouds, no atmosphere, no night — then beam that energy back to Earth as microwaves or laser light. Now, that concept is moving from whiteboard to contract.
Meta has signed a power purchase agreement with Overview Energy, a startup building infrastructure for orbital solar collection, in what marks Overview's first commercial contract. While the deal is modest in scale, its symbolic weight is considerable: one of the world's largest technology companies is putting money behind a technology that could fundamentally reshape how humanity generates and delivers clean energy.
Why Solar From Space?
The core appeal of space-based solar is reliability. Ground-based solar farms are limited by weather, geography, and — crucially — darkness. A solar farm in Arizona goes offline every night. A solar array in geostationary orbit receives sunlight nearly 24 hours a day and can transmit power on demand to receivers on the ground, regardless of local conditions.
That makes it particularly attractive to energy-hungry tech companies. Data centres — the backbone of AI, cloud computing, and social media platforms — run around the clock and require consistent, uninterrupted power. Renewable energy is increasingly the preferred source, but intermittency has always been a challenge. Space solar sidesteps that problem entirely.
A Small Step, But a Meaningful One
Overview Energy's contract with Meta is described as a small step, and it's worth keeping that in context. Space-based solar remains extraordinarily expensive and technically complex. Getting hardware into orbit costs millions of dollars per launch, and the engineering required to efficiently convert and transmit energy across hundreds of kilometres is still being refined.
But commercial contracts have a way of accelerating timelines. When a company like Meta commits to buying output from an emerging technology, it validates the business case, attracts further investment, and gives startups like Overview the runway to iterate and scale.
Several space agencies and private firms — including teams in the UK, China, and the European Space Agency — have been developing space solar concepts in parallel. A Meta-backed American startup entering the field adds competitive pressure and capital that could speed progress industry-wide.
What It Means for Clean Energy
The energy sector is watching closely. If space-based solar can achieve cost parity with ground-based renewables plus storage — a very big if, but no longer an impossible one — it would represent a leap in clean baseload power. Unlike nuclear, it doesn't require decades of permitting. Unlike offshore wind, it isn't constrained by coastal geography.
For now, this deal is a proof-of-concept moment: a signal that serious buyers exist, and that the market for orbital energy is beginning to take shape.
The sun, it turns out, is available for business around the clock. Humanity is just learning how to collect the bill.
