Roborough eco town, devon - zeroC

Photon Energy won the tender to install the 320 kWp of solar PV at Roborough in a competitive tender for ZeroC. Due to the location and size of the project, Wessex ECOEnergy, based in Dorset, were subcontracted to assist with the installation.

The houses, as part of the eco-friendly design, feature large asymmetric, pitched roofs that have been mounted with up to 24 solar PV modules. The larger sections of the roofs have been almost completely covered with in-roof panels, orientated in the optimal direction in for maximum energy generation.

Viridian Solar Clearline Fusion integrated modules were selected for this project as the seamless appearance of the in-roof panels was ideally suited to the modern aesthetic of the homes. Viridian Clearline Fusion 250 Wp modules have been installed for the majority of the houses, with 270 Wp panels specified for a few homes, to maximise the output of the PV on more limited roof areas.

Sofar Solar inverters have been installed, with a variety of different models incorporated to suit the mix of system sizes.

Rikki Baker, Project Engineer of Photon Energy said: “It has been a welcome change to work on a development where every aspect of energy efficiency and sustainability has been considered from the outset, delivering enormous long term benefits to the residents.”

Councillor Chris Penberthy, Shadow Cabinet Member for Cooperatives and Housing for Plymouth City Council, said: “This unique project will be the UK’s first large scale, zero carbon community that delivers direct economic benefits with sustainable jobs.”
