Photon Energy installed a 102 kWp PV system on Champion Hill student accommodation for Kings College, located in Denmark Hill, London.
Details of the installation
The PV system consists of 408 x Upsolar 250P polycrystalline PV modules. The PV modules are connected to ABB TRIO inverters that have been mounted at roof level to minimise the DC cable run. The modules have been mounted on the flat roof areas of the student accommodation using the Hilti low ballast mounting system. The system has been designed to deliver approximately 90,060 kWh per annum.
This new build student accommodation for King’s College, London, benefitted from a solar PV system designed and installed by Photon Energy, when it opened in September 2014. Although won under competitive tender, this was repeat business for Photon Energy as the contractor, Imtech North, now part of the Imtech Aqua Group, is a past customer.
The accommodation comprises four 4-storey blocks containing en-suite study bedrooms together with residents’ shared kitchen and dining facilities for over 700 students.
The nature of the building means that electricity use is high throughout the day for lighting, computers and all the other electronic or electrical devices that students need. This is in addition to the shared services such as lighting of the corridors.
The 408 PV modules were installed on the three flat roofs to deliver a projected 90,060kWh/year with an annual carbon saving of 47.6 tonnes of CO₂. The inverters were installed in fourth floor plant rooms and connected to distribution boards on the second floor of each block.
Chris McPartland, Senior Contracts Manager at Imtech, said, “Working with Photon Energy, we have found their approach to be proactive throughout all project stages, identifying potential cost savings thoughout, a professional installation team with a support based office team able to deal swiftly with any issues."
