ClearVue Technologies (ASX: CPV) has unveiled a game-changing advancement in its Gen3 solar vision glass, achieving a 66 per cent increase in energy output while slashing its production costs and complexity.
The company’s Gen3 windows can generate more than 50 watts per square metre power, or 66 per cent more than its predecessor, according to independent testing by the Solar Energy Research Institute of Singapore (SERIS).
The tests have validated the prototype’s enhanced performance and demonstrated it can harness solar energy effectively while maintaining transparency, marking an important milestone in ClearVue’s development of its patented energy-generation glazing and building technology.
SERIS’ rigorous evaluation also verified ClearVue’s streamlined manufacturing process for the glass, which cuts production time, costs and positions the technology as a highly efficient, sustainable solution for building-integrated photovoltaic products.
ClearVue’s managing director and chief executive officer Doug Hunt said the company has streamlined manufacturing, resulting in a reduction of processing time for double-glazed units from five minutes to just two.
The results of the SERIS testing demonstrate significant performance improvements. Independent validation from SERIS confirms that ClearVue Gen3 solar vision glass offers higher energy generation.

The new efficiency drive, coupled with a reduction in components from 17 to seven, minimises silicon waste, eliminates aluminium and lowers embedded carbon, which will help the company’s customers offset more building energy use while shortening payback periods for the materials.
The versatile new Gen3 glass is available in single, double or triple glazing, and can integrate with vacuum glass products produced by its joint venture subsidiary LandVac for enhanced thermal performance and aesthetic flexibility.
The new product is also compatible with standard framing systems and meets typhoon ratings, making it suitable for diverse global markets.
The enhancements place ClearVue as a leader in solar-integrated building materials and align the company with a global push towards decarbonisation and greener building standards.
The Gen3 glass is now ready for commercial quotes with full certification expected by mid-2026. All the core technologies were certified in prior generations.
ClearVue’s extensive development track record includes trial results released last month by Hong Kong’s Electrical and Mechanical Services Department for its integrated solar façade.
The trial tested ClearVue’s innovative vacuum-insulated solar glazing unit developed in a strategic partnership with a subsidiary of its joint venture partner, advanced glass company LandGlass Technology.
ClearVue then applied the Hong Kong results to a hypothetical 40-storey building with a 50 per cent window-to-wall ratio in 15 cities, which showed the product could offset 74 per cent to 125 per cent of a building’s annual energy needs, further advancing the path to net-zero buildings.
The trial, which began in July 2024, points to a 4.6-year payback period before subsidies for ClearVue’s solar vacuum-insulated façade. When Hong Kong’s feed-in tariff is included, the panels pay for themselves in 2.6 years.
ClearVue has been working since 1995 to integrate solar technology into building surfaces such as windows, skylights and cladding to generate clean energy while preserving aesthetics. The company also envisages transforming buildings into power-generating assets.
With a scalable licensing model and partnerships, including LandGlass’s vacuum-insulated glazing, ClearVue is poised for global expansion, particularly in key markets such as the United States and South East Asia. It recently raised $7.5 million in Hong Kong to boost its operations.
