St Mary’s Catholic High School Solar Installation, Chesterfield

279-76kw-school-solar-panel-installation-chesterfield1St Mary’s is an 11-18 Catholic Voluntary Academy serving North East Derbyshire. A thriving, highly successful and over-subscribed school with a long and well established reputation. With an outstanding record of academic achievements and examination results consistently well above the national average.The students are wonderful ambassadors: hardworking, friendly, fun to be with and polite young people. They are supported by an outstanding team of staff who are united in encouraging and challenging all our students to be the best they can be.  The school ground covers a large footprint and this large footprint came with an equally large electricity bill. The power demand on site covers a total of more than 20 buildings and as such required an impressive and innovative solution.

Custom Solar planned, designed and installed a 280kw system to feed the two on site meters and where possible reduce electricity demand to zero.

Since the installation the school has seen a dramatic decrease in electricity consumption and a massive impact on CO2 savings. All of this was achieved through Custom Solar’s access to funding which provided a large percentage of the project cost.

The school are now one of the most energy efficient throughout the Country and use this newly found glory to further educate their students on power efficiency and renewable energy.
