Y Twyni, Swansea University, Swansea

At Swansea University’s Y Twyni building, 1 Vision Solar delivered a 134.55 kWp solar PV installation, combining both flat roof arrays and a purpose-built solar carport. This project forms part of the university’s wider sustainability strategy, helping to reduce reliance on grid electricity and cut long-term operating costs.

The flat-roof PV system was designed with optimised mounting to maximise generation across the year, while the integrated carport provides dual functionality: renewable energy production and sheltered parking for staff and students. Together, the systems will generate significant clean electricity onsite, contributing to the university’s ambitious carbon reduction goals.

As with all 1 Vision Solar projects, the installation was delivered in line with MCS standards, CDM regulations, and best-practice safety requirements. Detailed planning and coordination ensured minimal disruption to the busy university campus, with the final design balancing aesthetics, efficiency, and practicality.

The 134.55 kWp system is expected to generate around 115,000kWh annually, offsetting a large proportion of the building’s electricity demand and delivering measurable carbon savings each year.

This project highlights how educational institutions can make a tangible impact on climate goals by adopting on-site renewable energy. Swansea University can now showcase the Y Twyni installation as a visible symbol of its commitment to sustainability, providing not only environmental benefits but also an educational tool for students and the local community.
