During the summer recess of 2024/25, Emmanuel College undertook a transformative sustainability initiative with the installation of a 279kW solar energy system. The landmark project underscores the College’s commitment to environmental stewardship and renewable energy.
This large-scale installation not only represents a significant step toward reducing the College’s carbon footprint, but also offers long-term financial benefits by lowering energy costs and enabling reinvestment into future campus developments. The project also made strategic use of previously untapped roof space, reducing daytime reliance on the local power grid.
Following a comprehensive tendering process, the College partnered with DS Energy, a Brisbane-based solar installer. The scope of the project focused on maximising the available roof space across the wings surrounding the quad, while maintaining the architectural integrity of the College.
One of the key challenges was the age of the quad’s roof structures—many over 70 years old and not originally designed to support the weight of photovoltaic (PV) panels. DS Energy overcame this with innovative engineering solutions, allowing the installation to proceed without compromising safety or aesthetics.
Installation began in December 2024 and brought further unexpected hurdles. As anticipated, some of the aged terracotta tiles cracked during the process. To preserve the College’s heritage aesthetic, an identical supply of tiles was sourced from a roofing merchant just 12km away. Additionally, the electrical infrastructure feeding the individual wings required upgrading to safely accommodate the new system and ensure efficient energy distribution.
After final approval from Energex and a successful testing phase, the system was officially activated on 22 August 2025. Since then, the College has recorded an average daily yield of 1,200 to 1,400 kWh on consistently sunny days.
Speaking on the impact of the project, Principal Stephen Peake said:
“This initiative not only aligns with our environmental values but also delivers measurable financial benefits. The long-term cost savings generated by the solar system enhance our capacity to invest in areas of our operations which will enhance our residents' experience and the College's longer-term infrastructure.”
Looking ahead, the College is already exploring the feasibility of on-site battery storage, which would allow for greater energy self-sufficiency during evenings and overcast days, further reinforcing Emmanuel’s commitment to sustainable innovation.
