Solar Power at Night: How Overview Energy Plans to Beam Energy From Space Using Lasers

Solar power at night? It's no longer science fiction.

Meet Overview Energy, a Virginia-based startup with a bold vision: collect sunlight in space and beam it down to Earth using lasers. No more idle solar farms when the sun sets. No more intermittency. Just clean, reliable power—24 hours a day, 365 days a year.

The Problem

Solar energy is abundant and clean, but it has one fatal flaw: it only works when the sun is shining. At night, solar farms sit idle. On cloudy days, output plummets. Batteries help, but they're expensive and limited.

Overview Energy asked a different question: instead of storing energy on Earth, why not collect it where the sun never sets?

The Solution: Space-Based Solar Power

Satellites in geosynchronous orbit—36,000 kilometers above Earth—will harvest sunlight continuously, never blocked by night or clouds. That energy is converted into near-infrared laser beams and transmitted to solar farms on the ground.

The breakthrough? No new infrastructure needed. The lasers simply "re-illuminate" existing solar panels, allowing them to generate power at night just as they do during the day.

How It Works

Satellites in orbit: Each satellite is packed with massive solar arrays, with over 90% of its structure dedicated to collecting sunlight.

Near-infrared lasers: Safer, smaller, and more efficient than microwave-based systems. Standing in the beam? About as intense as sunlight on a snowy day.

No new ground hardware: Uses standard solar panels already in place.

Dynamic distribution: One satellite cluster can serve multiple continents, shifting power where demand is highest.

The Milestone

In November 2025, Overview Energy proved it works. The company successfully transmitted power from a moving Cessna Caravan aircraft flying at 5,000 meters to a ground receiver five kilometers below—using the same optics and laser chain destined for space.

It's believed to be the world's first high-power wireless energy transmission from a moving platform.

The Roadmap

2028: Low Earth Orbit satellite demonstration

2030: First commercial operations in geosynchronous orbit

The company has already booked a SpaceX rideshare mission for 2028.

Why It Matters

24/7 clean energy: Baseload power without fossil fuels

Higher efficiency: Space panels generate up to 13x more power than ground panels in cloudy regions

No land use conflicts: Uses existing solar farms

Grid resilience: Power can be redirected instantly during emergencies

The Challenges

Cost remains the biggest hurdle. Cloud cover can block lasers. Atmospheric losses, orbital debris, and regulatory frameworks all need solutions.

But Overview Energy has already raised $20 million from top investors—and proven its core technology works.

The Bottom Line

As CEO Marc Berte puts it: "This isn't science fiction. The technology works, and now it's scaling up."
