Marlborough Primary School is part of the REAch South Academy Trust. The Primary School is based in the heart of Plymouth and is in an old granite building that has proven hard to heat and light effectively resulting in large energy bills.

Bright Spark Energy were asked to design a solution that not only reduced the energy consumption of the buildings but also to improve lighting quality.  We were asked to provide a Solar PV system in conjunction with an LED Lighting project to reduce the reliance on grid bought electricity.  The School was using 69,500 kWhs per annum for Electricity paying a high electricity rate.

Solar PV System – reducing the energy from the grid.

We proposed and installed a 49.8KWp Solar PV System at Marlborough Primary School subsidised by a Social Enterprise operating rental with no upfront cost to the School. 

Using the standard MCS yield calculator we calculated the following yields for the installation.

Performance 12 months on

We have been tracking the performance of the Solar PV system as the O&M partner to the social enterprise funder using the Meter Online enabled Solar PV Meter– in the past 12 months the system has worked well and outperformed our initial expectations. 

Expected Actual

Yield (kWhs) 49,950 . 52,667.8

Export (kWhs) 7,492 27.3

Electricity Saving (£) 5,094.90 6,320.14

FITs Income (£) 2,157.84 2,275.25

Export Income (£) 367.88 0


The School has consumed almost all of the Solar PV generated maximising self-consumption and increasing the savings generated to be re-invested back in to Teaching and Learning.

After paying the operating rental quarterly in arrears the Primary School will generation a net saving of £ 3,100.01 to invest back into the social mission of the fund – to further the educational outcomes of disadvantaged children.
