DragonSCALES versus gallium arsenide: why the solar race in orbit is suddenly heating up

The space industry has long relied on gallium arsenide (GaAs) solar modules as the gold standard for power generation in orbit. Their high efficiency and durability have made them indispensable for decades of satellite missions. But as costs rise, satellite constellations multiply, and resilience becomes more critical, the sector is witnessing a technological challenge that could reset the market.

At the center of this disruption is DragonSCALES, a flexible solar module platform developed by mPower Technology. The company recently secured a strategic investment from Lockheed Martin Ventures, giving its technology not only financial support but also validation from one of the largest defense and aerospace contractors in the world. This backing comes as Airbus Netherlands has already adopted DragonSCALES for Sparkwing solar arrays, which will power satellites in the Aurora constellation and potentially next-generation low-earth orbit networks.

How does DragonSCALES compare with traditional gallium arsenide solar technologies?

The core distinction lies in flexibility and scalability. Gallium arsenide modules, while efficient, are rigid and expensive to produce. Their manufacturing processes are slow, and scaling production has historically been difficult. DragonSCALES, in contrast, uses a modular architecture that allows solar sheets to be produced in high volumes on automated lines. The company’s facility in Conklin, New York, is expected to deliver more than two megawatts of DragonSCALES annually, a figure that exceeds the combined global output of legacy GaAs suppliers.

This industrial scale signals a fundamental shift. In an era where satellite constellations like Telesat Lightspeed and Globalstar aim to deploy hundreds of satellites, cost per watt and resilience are paramount. DragonSCALES not only reduces costs but also enhances survivability. With a distributed architecture, the system can isolate localized failures, preventing them from cascading into complete power loss. GaAs modules, though durable, are vulnerable to single-point failures that can compromise entire panels.

Radiation resilience is another differentiator. DragonSCALES has been engineered to withstand the hostile space environment, with redundancy built into its network-like design. As low-earth orbit becomes increasingly crowded with constellations, the ability to survive micrometeoroid strikes or radiation storms without catastrophic loss could make the difference between profitable operation and costly replacements.

Why is the competition between DragonSCALES and gallium arsenide heating up now?

Several structural trends explain why this rivalry is intensifying. First, the economics of launch have changed. With companies like SpaceX and Rocket Lab lowering costs through reusability and scale, more satellites are being launched than ever before. The satellite market has shifted from one-off geostationary platforms to mass-produced LEO constellations, where power solutions must be cost-efficient and quickly deployable. DragonSCALES fits this new industrial model far better than gallium arsenide.

Second, geopolitical priorities are reshaping procurement. Governments now view space as a contested strategic domain, and power availability has become a mission-critical enabler. The U.S. Department of Defense and its allies are pressing for redundancy and distributed resilience in orbital assets. DragonSCALES, with its modular, fault-tolerant design, aligns more closely with these defense-driven requirements than traditional rigid GaAs modules.

Finally, investor sentiment is playing a role. The decision by Lockheed Martin Ventures to back mPower signals to institutional investors that the technology is ready for large-scale adoption. Venture funds specializing in defense and aerospace have already increased exposure to dual-use technologies, while commercial satellite operators are seeking alternatives that cut costs. The result is a convergence of financial, commercial, and defense interests around flexible solar modules.

What could this mean for the future of space solar manufacturing?

The implications are significant. If DragonSCALES continues to demonstrate performance advantages, legacy GaAs producers could see market share eroded as customers pivot toward cost-effective, resilient alternatives. In the long run, gallium arsenide may remain relevant for specialized missions where maximum efficiency outweighs cost considerations, such as deep-space probes. But for the booming LEO satellite market, where replacement and scale economics dominate, DragonSCALES appears better positioned.

This raises broader questions about the future structure of the space supply chain. With Airbus, Lockheed Martin, and other primes now signaling support for next-generation solar technologies, analysts expect potential consolidation. Either legacy GaAs suppliers will adapt by acquiring or partnering with flexible solar innovators, or they risk being marginalized as new entrants scale production.

For investors, the takeaway is that the solar race in orbit is no longer just about efficiency metrics; it is about manufacturability, resilience, and integration into constellation economics. As capital flows increase into space energy solutions, companies that can demonstrate high-volume reliability are set to attract premium valuations.

The race between DragonSCALES and gallium arsenide is not just a battle of materials science. It is a proxy for how the new space economy values innovation: cost-effective, scalable, and resilient technologies are now in demand. With Lockheed Martin Ventures’ backing, DragonSCALES has momentum on its side, and the coming years will reveal whether legacy incumbents can adapt or whether the new flexible model becomes the industry standard.
