Introduction
Located in the heart of Liverpool, John Moores University (LJMU) has committed to an ambitious sustainability goal to achieve Net Zero Carbon (NZC) by 2035. As part of their vision, the university launched a Carbon Management Plan following its declaration of a climate emergency in 2020. To support this initiative, our team was appointed to deliver a high-efficiency solar PV installation across three key university buildings. This project plays a vital role in reducing carbon emissions and supporting the university’s transition to sustainable energy sources.
Methodology
To identify the most effective renewable energy solution, our team conducted detailed energy and structural surveys of LJMU’s available roof space. Over 3000m² of potential space was analysed, with priority given to installations offering the best return on investment in terms of carbon savings per pound spent. We proposed the deployment of 71 LONGi 460W solar panels, complemented by SolarEdge Power Optimisers. This system design ensured each panel could perform independently, significantly increasing output even under partial shading or soiling conditions. A phased installation plan was developed to minimise disruption to campus operations.
Installation
The installation phase involved working across three multi-level roofs, each presenting unique logistical challenges. Using cranes, we safely lifted all equipment onto the designated rooftops. Panels were mounted using the robust Vandervalk flat roof mounting system, chosen for its durability and compatibility with varied roof structures. A biosolar roof that combines green roofing with solar PV was included in the installation, with future expansion planned pending trial results. Each roof was fitted with a dedicated inverter to optimise energy conversion. This meticulous setup delivered a total system output of 32kW, generating an estimated 29,000kWh of clean electricity annually.
Outcome
The successful completion of this solar PV installation marks a significant step in LJMU’s path to Net Zero Carbon. The university now benefits from zero-carbon electricity generation, reduced energy costs, and long-term environmental value. The system is already contributing to lower carbon emissions while demonstrating LJMU’s leadership in sustainable education. Future expansion plans will further enhance these benefits.
