LOFC Stadium Case Study
LOFC 350Kw Solar Panel Installation
Leyton Orient Football Club, based in East London, sought to reduce their carbon footprint and energy costs by installing a 350kW solar photovoltaic (PV) system on their stadium's roof. The installation took place during the off-season to minimise disruption to club activities and match-day operations. Scope was chosen for our expertise in large-scale solar installations and our track record with commercial projects.
What Did We Want To Accomplish?
-
Reduce Energy Costs: Offset a significant portion of the club's electricity usage with renewable energy.
-
Promote Sustainability: Demonstrate Leyton Orient's commitment to environmental responsibility.
-
Utilise Unused Space: Efficiently use the large roof area of the stadium.
How Did LOFC Benefit?
Energy Savings: The system is projected to generate approximately 300,000 kWh annually, significantly reducing the club’s energy bills and reliance on non-renewable energy sources.
Environmental Impact: The installation offsets around 150 tonnes of CO2 annually, contributing to the club’s sustainability goals and enhancing their green credentials.
​
Community Engagement: Leyton Orient leveraged the installation as a cornerstone of their community outreach, educating fans and the local community about renewable energy and sustainability.
Brand Enhancement: The project has positively impacted the club’s brand, showcasing their commitment to innovation and environmental stewardship.
Project Planning and Design
​ 1. Feasibility Study:
The initial phase involved an all-encompassing feasibility study, including:
-
Roof Assessment: Structural analysis of the stadium's roof to ensure it could support the weight of the solar panels and associated equipment. This involved detailed load calculations and coordination with structural engineers.
-
Energy Audit: Assessment of the club's historical electricity consumption to size the system appropriately.
-
Shading Analysis: Use of solar irradiance data and 3D modelling to determine the optimal placement of panels, avoiding shading from nearby structures and natural features.
2. System Design:
The design phase included:
-
Selection of Panels and Inverters: Chosen for their efficiency, durability, and warranty terms. High-efficiency monocrystalline panels were selected, paired with central inverters to maximise energy conversion.
-
Electrical Design: electrical schematics, including cable runs, junction boxes, and connection to the stadium’s electrical infrastructure.
-
Monitoring System: Integration of a state-of-the-art monitoring system for real-time performance tracking and maintenance.
Installation Process
1. Permitting and Approvals:
All necessary permits and approvals were obtained, including planning permission from the local council and grid connection agreements with the distribution network operator (DNO).
2. Site Preparation:
During the off-season, preparatory work included:
-
Scaffolding and Safety Measures: Erecting scaffolding and implementing safety protocols, ensuring compliance with health and safety regulations.
-
Roof Reinforcement: Minor reinforcements were made to the stadium’s roof to accommodate the additional load.
3. Solar Panel Installation:
The installation was executed in several stages:
-
Mounting System Installation: The racking system was securely fixed to the roof. This system supports the solar panels and allows for optimal tilt angles.
-
Electrical Work: Inverters and electrical components were installed, followed by the wiring of panels. This phase required meticulous attention to ensure safety and compliance with electrical standards.
4. Testing and Commissioning:
Post-installation, the system underwent thorough testing:
-
Electrical Safety Tests: Verification of proper grounding, insulation, and system integrity.
-
Performance Testing: Ensuring the system met expected output levels, with adjustments made as necessary.
-
Grid Connection: Finalisation of the grid connection, allowing excess energy to be fed back into the grid under the terms of a Power Purchase Agreement (PPA).
