Orchard Field School meets it high demand within strict grid restrictions
Orchard Field Community School is a large primary school in Banbury, Oxfordshire and a member of the Low Carbon Hub Solar Schools portfolio. The installation was installed in Summer 2015.
Orchard Field Community School is a large primary school with a very high energy demand. The school’s roof along with being large also curves around in a crescent moon shape. This presented a challenge in terms of how to secure the panels to the roof. The lengths of rail which we normally used on gable roofs couldn’t be used. This also presented a challenge in terms of how best to wire the solar PV modules to the inverters, as panels facing in slightly different directions have different outputs depending on the location of the sun. Orchard Field was therefore a tricky set up.
The final challenge was also to limit the potential export to the national grid. Despite the high demand on site solar PV export was limited to 50kWp, meaning that we needed to find a way to prevent the PV system from generating 50kWp more than the demand on site at any point in time – a very likely occurrence over the summer holidays.
On a clear spring day the solar PV system meets the total energy demand on site. During the Summer this happens more and more. Whatever the weather this system makes a significant reduction to the School’s electricity bills. And like all our installations in schools it has become a valuable educational tool for the pupils.
Why they chose Joju?
Joju have been one of the preferred suppliers of the Low Carbon Hub for several years and Orchard Croft is just another fantastic example of us working with them.
Headmistress Dawn Shilston said “As a school we feel incredibly proud to be doing our utmost to reduce our Carbon Footprint. It is incredible to consider we are the largest Solar Roof Project on a Primary School in Oxfordshire with our school roof hosting 384 solar panels. It has been an invaluable exercise in educating our pupils for the future on the importance for us all to explore the possibility of using renewable resources for our energy.”
