Located on top of the Chingford branch of supermarket Sainsburys, the 67.48 kWp system is expected to generate over 57,356kWh of solar electricity a year.
The company said the array was installed and working within three weeks. It is comprised of 300 Romag SMT6 solar panels, covering an area of 415m2.
GHL added that Active Technologies designed and manufactured the aluminum framing system for the arrays, while Q Design Consultants handled the electrical design and arranged the G59 submission to EDF.
Furthermore, RoofTech installed the frames and the photovoltaic (PV) panels, and also arranged the electrical engineers to wire the system together. Natural Watt and Energy ICT provided the energy monitoring equipment for the system, while the energy meter was supplied by Elsevier. The solar inverters for the system were supplied by Fronius and were IG 60.
