Campbell & Kennedy was appointed to deliver the installation of 130kWp solar PV system to the roof of Gibson Road car park by Sutton Council. The award followed a competitive tendering process which was undertaken via the Procurement for Housing (PfH) Renewable Energy and Efficiency Works’ framework.
The Council wanted to utilise the electricity generated by the solar PV system to supplement the power supply for both the car park and their office.
This was the second phase of works, with the first being a solar PV installation to Sutton Council’s Civic Office. The first phase, also installed by Campbell & Kennedy, was also procured via the PfH framework.
Prior to commencing work on site, C&K carried out a detailed structural survey in order to adequately determine the suitability of the proposed solar PV panels. This survey enabled us to optimise conditions for the delivery of works, allowing us to contemplate aspects such as shading, site access and shut down procedures. Performance comparisons were completed utilising different panels and inverters. Following this detailed initial survey, we appointed a dedicated team to carry out the installation of the Solar PV panels.
As we had carried out a detailed survey prior to the initiation of the works, we were able to pre-emptively act in order to avoid any challenges relating to the site. Faced with logistical access issues, we utilised telehandlers to lift each individual component of the system to its 14-metre high site position on the carpark roof space. Operating within restricted height parameters on each floor of the building and working throughout the night to prevent road closures, we successfully installed the system with minimal disruption to the Sutton area.
The resulting carport is sized at 133kWp, covers 57 car parking spaces and holds 492 solar panels. The system is expected to generate approximately 120,000kWh of energy per year, making the car park almost energy neutral, using only renewable energy to fully operate.
Additionally, our design has served to accommodate potential future developments and additional works for Sutton Council. Further energy savings were made possible as our design also serves LED lighting and EV charging.
Ian Watts, Energy Manager at the London Borough of Sutton said: “Campbell & Kennedy carried out a phenomenal job in understanding not only our technical needs but also all the political, environmental and social considerations that are involved in a Council-owned solar PV project. They have been amazing partners and a key element to the success of this project.”
