Dutch Teams Bring Cheaper Solar Panels to Space

Solar panels that power millions of homes could soon be heading to orbit, slashing the cost of satellite missions.

Dutch research institute TNO, solar manufacturer MCPV, and aviation giant Airbus are teaming up to adapt everyday silicon solar panels for use in space. If successful, the project could replace the expensive gallium arsenide solar cells currently used on most satellites.

The difference in cost is striking. Today's space solar arrays rely on materials that are both pricey and difficult to source. Meanwhile, silicon solar technology has become remarkably affordable and efficient through decades of development for rooftop and ground installations.

The challenge is making sure these Earth-tested panels can survive the brutal conditions of space. The teams are studying how silicon solar cells hold up against intense particle radiation, extreme temperature swings, and the mechanical stress of launch and deployment.

TNO is contributing its expertise in back-contact silicon solar cells, which allow for more precise manufacturing. MCPV brings industrial production knowledge to scale up the technology. Airbus Netherlands provides decades of experience integrating systems into satellites.

The collaboration starts with sharing technical knowledge and identifying which terrestrial solar concepts make the most sense for space. Early tests will focus on performance under space-specific conditions that don't exist on Earth.

"Terrestrial photovoltaics have evolved enormously in terms of manufacturability, cost, and design flexibility," said Harald Kerp, Senior Business Developer at TNO. The key question is whether those strengths translate to space while meeting strict reliability requirements.

Why This Inspires

This project shows how solutions developed for one challenge can unlock opportunities somewhere completely different. The same technology that helps families reduce their electricity bills could soon power the satellites that provide communications, weather forecasting, and scientific research.

The timing matters too. As Europe works to strengthen its independence in space technology, building on proven systems rather than starting from scratch offers a faster, more reliable path forward. A stronger supply chain means fewer delays and more ambitious missions.

The initiative could democratize access to space by making satellite technology more affordable for smaller companies and research institutions. When costs drop, more innovation becomes possible.

Turning yesterday's rooftop technology into tomorrow's space solution proves that the best answers often come from looking at old problems in new ways.
