01 / THE CHALLENGES
Delivering solar within a heritage campus called for careful staging, structural expertise and close attention to the College’s established architecture.
Keeping campus ready
Installation was staged during summer recess so the College remained safe, accessible and ready for returning residents.
Working with heritage roofs
Roof structures over 70 years old, terracotta tiles and solid brick construction called for structural assessments, verified racking and specialised installation methods.
Preserving the College’s character
Cracked terracotta tiles were replaced with locally sourced matching tiles to maintain the campus’s established appearance.
Upgrading the electrical network
The distribution network serving the individual wings needed upgrades to integrate solar safely and support efficient long-term performance.
THE SYSTEM AT WORK
From site to useful energy
Site assessment
Converts sunlight into clean electricity.
Tailored design
Upgraded infrastructure moves energy safely across the site.
Delivery and care
On-site generation helps reduce reliance on the grid.
02 / THE SOLUTION
Following a comprehensive tender, Emmanuel College selected DS Energy to deliver a system that made the most of available roof space while respecting the campus’s heritage character.
System
275.52 kW rooftop solar
Modules
ASTRONERGY CHSM60N(DG)/F-HC · 480 W
Mounting
Engineered for heritage terracotta roofing
Infrastructure
Upgraded electrical distribution network
The installation combined roof-specific structural mounting with electrical upgrades, protecting safety, structural integrity and architectural design. Work began in December 2024; Energex approval and successful commissioning enabled activation on 22 August 2025.
03 / THE RESULTS
The system is projected to generate approximately 387.7 MWh each year, reducing the College’s reliance on grid electricity during peak daytime hours. The reported operational results show that impact taking shape.
Projected annual generation
CO₂ avoided since commissioning
kWh generated on sunny days
Lower energy costs
Reduced daytime grid demand supports lower operating costs.
Greater resilience
On-site solar strengthens the College’s long-term energy position.
More capacity to reinvest
Long-term savings can support residents and future infrastructure.
“This initiative not only aligns with our environmental values but also delivers measurable financial benefits.”
Stephen Peake · Principal, Emmanuel College
LOOKING AHEAD
The next chapter: on-site storage.
Emmanuel College is exploring battery storage to further strengthen energy self-sufficiency. The long-term savings from solar can support investment in residents’ experience and the College’s future infrastructure.
