Bentleywood Highschool

The Challenge

Bentley Wood High School in North London was struggling with rising energy bills. With high demand across classrooms, ICT suites, and sports facilities, electricity costs were becoming a major strain on budgets. Alongside this, the school wanted to demonstrate environmental leadership, aligning with government net-zero targets and setting a visible example for its students and wider community.
The challenge was clear: cut costs, reduce carbon emissions, and deliver long-term energy security — all with minimal disruption to learning.

The Solution

EcoGlow designed a bespoke 50kW commercial solar PV system tailored to the school’s energy usage and roof capacity. The system included:

• 1 x Solis 50kW inverter for maximum reliability

• 120 DMEG 440W solar panels — ethically sourced and manufactured without child labour or exploitative practices, reflecting EcoGlow’s and the school’s shared moral values

• A real-time monitoring system to track performance and generation

The project was delivered by EcoGlow’s in-house MCS-accredited and TrustMark-certified team, ensuring the highest standards of workmanship and accountability. Unlike contractors who outsource, EcoGlow manages every stage directly — from surveys and planning to installation and compliance.

The physical on-site installation — scaffolding erection, panel mounting, wiring, inverter connection, and commissioning — took just three weeks. All structural surveys, planning permissions, and DNO applications were handled in advance, making the process seamless for the school with minimal classroom disruption.

Results & Savings

• Annual Generation: 45.013 MWh of clean, renewable electricity

• Annual Financial Savings: £10,956 in reduced energy bills

• Payback Period: Just over 4 years

• Installation Cost: £46,750

• Lifetime Impact: Nearly £450,000 in projected savings over the system’s lifespan

Real-World Impact

The Bentley Wood installation delivers far more than cost savings.

• Carbon Reduction: By generating 45 MWh of renewable electricity annually, the school avoids around 10 tonnes of $CO_2$ emissions every year — equivalent to planting 450 trees annually or eliminating 30,000 car miles.

• Energy Equivalent: Enough electricity to power around 12 average UK homes for an entire year.

• Educational Value: The system provides students with real-time renewable energy data, turning sustainability into a living classroom resource across science, geography, and environmental studies.

• Financial Resilience: With nearly half a million pounds in lifetime savings, the school has greater long-term stability against energy price rises. These savings can be redirected into ICT upgrades, science lab modernisation, new sports facilities, or additional teaching support, directly benefiting students.

Benefits to Bentley Wood High School

• Lower Costs: More than £10,000 saved annually on electricity bills.

• Sustainability Leadership: Demonstrates environmental responsibility to students, staff, parents, and the community.

• Ethical Values: Panels and equipment sourced responsibly, reflecting EcoGlow’s commitment to fair supply chains.

• Seamless Delivery: End-to-end project management, with EcoGlow handling every stage — from planning to certification.

• Future Gains: A system built to perform for 20–25 years, locking in both financial and environmental benefits.

Summary

The Bentley Wood High School project demonstrates how a carefully designed solar PV installation can deliver immediate savings and long-term sustainability gains. By choosing EcoGlow, the school received not only high-performance technology but also a trusted partner committed to responsible sourcing, seamless delivery, and ongoing support.

The three-week on-site installation was completed with minimal disruption, while all compliance, approvals, and documentation were handled behind the scenes. The result is a school that is not only cutting costs but also creating a powerful teaching resource, strengthening resilience, and showing environmental leadership.
