The Chafford School is a mixed comprehensive school for 11 to 16 year old students, with just under 1000 pupils. The forward looking, modern ethos of the school, combined with their status as one of the Department for Education & Skills' Specialist Business & Enterprise Colleges, means they are always looking ways of providing pupils with real-world examples of 21st century technology and business practices. That motivation, combined with a desire to reduce the school's carbon footprint and long-term energy costs made an onsite renewable energy system a natural choice. After considering the available options, a PV system was chosen for it's high educational value, ease of installation and low maintenance costs.
Myriad CEG Power Ltd were selected as suppliers and installers after the successful completion of a 4.2kWp system at Elm Park Library, also in Havering. Myriad Segen's sales, grant and engineering teams worked closely with all the parties involved to ensure the project progressed as smoothly as possible.
The total project value was £130,000, with 50% funding coming from the Phase 2 of Low Carbon Buildings Programme, 40% from Havering borough Council and 30% raised by the school.
The Chafford School's solar PV system comprises 150 roof mounted Sharp NU-180 Photovoltaic panels, with a total area of 195sqm. These 180w monocrystalline units generate renewable energy during daylight hours by converting the sun's energy into electricity. The power is fed into the school's supply and used onsite, with any excess automatically spilled to the local grid network.
With an expected lifespan of over 25 years and no annual maintenance required, the system will be benefiting the school for years to come.
The PV system acts as powerful education tool, thanks to the digital display and network-connected data logger. These record real-time and historical information about system performance and make it available to the whole school.
The data is used by the pupils and teachers as part of the curriculum, adding a 'real world' focus to science, geography, technology, economics and business lessons. Output can be compared with weather patterns, energy savings calculated and project economics analysed.
