Australian Glass Generates Power While Keeping Windows Clear

Imagine if every window in an office building could generate electricity while still letting sunlight stream through. That future just got closer thanks to a manufacturing breakthrough from Perth-based ClearVue Technologies.

The company developed solar glass that generates power while maintaining up to 80% transparency, producing over 50 watts of energy per square meter. Until now, one major roadblock stood in the way of widespread adoption.

ClearVue just announced its energy-generating glass can now accept the same heat-control coatings used on regular commercial windows. This means architects, engineers, and glass manufacturers can work with solar glass using the exact same tools and processes they already know and trust.

The technical achievement centers on applying a special low-emissivity coating after the solar cells are already embedded in the glass. These coatings help control how much heat enters a building and are standard requirements for modern commercial buildings worldwide.

"This removes a practical barrier for the industry," said ClearVue CEO Doug Hunt. "It means energy-generating glass can be considered alongside conventional façade products, rather than requiring an entirely separate design or manufacturing process."

The company validated its approach at a glass manufacturing facility in Germany, where the solar glass units were cleaned, coated, and tested on the same production line as regular glass. No special equipment or process changes were needed.

ClearVue believes it's currently the only building-integrated solar provider offering this capability. Other solar glass products typically require triple-pane window units, which reduces the thermal performance benefits.

The Ripple Effect

This breakthrough could accelerate the adoption of energy-generating buildings across cities worldwide. Architects can now specify solar glass without redesigning their projects or asking manufacturers to retool their facilities.

The timing aligns with growing pressure to reduce building energy consumption, which accounts for nearly 40% of global carbon emissions. Turning windows from passive features into active energy producers offers a practical path forward.

ClearVue recently secured major international certifications for its solar glass products and earned approval from Australia's Clean Energy Council. The approvals mean the technology qualifies for government grants and subsidy programs, making it more accessible to developers.

For an industry often resistant to change, making innovation fit seamlessly into existing workflows could be the key to widespread transformation.
