Techniquest, Wales’ leading Science Discovery Centre, is embracing sustainability by powering its iconic building in Cardiff Bay with solar energy. In partnership with Carbon Zero Renewables, the site now benefits from a cutting-edge rooftop solar system featuring Vertex S+ 500 W+ modules, reinforcing its commitment to innovation, education, and environmental responsibility.

Situated on the historic docks of Cardiff Bay, the Techniquest building blends industrial heritage with scientific exploration. The structure, once central to shipbuilding in the area, retains features such as an internal crane gantry and a distinctive curved, seam-clamp roof. Now, 25 years after its transformation into a science centre, it has taken a bold step towards a cleaner energy future.

The solar system is expected to generate approximately 114,630 kWh annually, offsetting 22.17 tonnes of CO₂ emissions and saving the centre around £28,000 each year. During daylight hours, the building is projected to operate entirely on solar power.

Gareth Jones, Managing Director at Carbon Zero Renewables, shared his thoughts on the project:

“Trinasolar has been our preferred module provider for a number of years. The new 500 W+, n type, dual-glass panels we used on this project gave us the versatility to deliver on a high level. The module’s characteristics allow for an overall cut down on system setup costs.”

This installation at Techniquest not only reduces operational costs and environmental impact, but also serves as a visible demonstration of clean energy in action — fitting for a centre that educates the public about science and technology. It stands as a beacon of how historic buildings can adapt for a more sustainable future without compromising their character or purpose.
