Chislehurst and Sidcup Grammar


28.5 kWp Solar PV systems installed on the new sixth form building in Sidcup.

Ecolution installed a 28.5 kWp solar photovoltaic system on the new sixth form building at Chislehurst and Sidcup Grammar School situated in Sidcup, London.

The Grammar School opened in 1931 but has only been at its current location for the past 50 years. As part of a combined project between Chis and Sid and London Borough of Bexley they erected a new building to provide additional dedicated sixth form facilities. This building which was previously the BMW pavilion from the 2012 Olympics and Paralympics, the grand opening of the new building was done by Boris Johnson, Mayor of London. The building contractors for the site utilised the existing steel frame when constructing the building and installed a new Bauder roof.

The school is dedicated to sustainability and decided the go with solar PV as it was an opportunity for the school to save on the running costs of the building by utilising the free electricity generated by the solar panels. Another opportunity was that they could take advantage of the Feed-in Tariff (FIT), freeing up, even more, money which could be better invested elsewhere within the school.

Chislehurst and Sidcup Grammar School originally tried to use solar PV financing, however, the Education Funding Agency (EFA) have very strict rules about lending which resulting in their application being declined. This then meant that Chis and Sid would be unable to proceed with the renewable installation however at Ecolution we were able to offer them an alternative with one of our own solar PV funding options. We were able to install the solar photovoltaic system at zero cost to the school and put in place a Power Purchase Agreement (PPA) for 20 years making this a feasible option again. This means the school not only cut their carbon footprint but also a cheaper daytime electricity rate compared to the national grid whilst we re-cooperate our costs from the PPA and FIT.
We liaised with both the building contractor and school when designing the system to ensure all their requirements were met. The final design incorporated 250w polycrystalline solar panels on a flat roof Light Tegra mounting system.

Chislehurst and Sidcup Grammar Schools now have built for the future benefiting from reduced energy bills freeing up extra cash which can be better reinvested into the school. Their solar photovoltaic system is now generating approximately 24,224 kWh of free electricity each year with C0₂ savings of 12,815.03 kg.
