To reduce energy costs and promote solar and sustainability to the Happy Frog customers. The challenge was to maximise the available roof space avoiding shaded areas by parapets and other obstructions. The customer requested a system that would maximise self-consumption.

Shading from the east and west parapets was overcome by pitched arrays where the shade would normally have fallen. Each of these orientations was connected to input A on each inverter. The two centre arrays were connected to input B of each inverter. The result was a production that closely matched the customer’s energy usage profile; this was verified by data logging.
Public awareness of PV was achieved with a graphic display of greenhouse gas offset and kWh production in the main dining area using the Sunny Portal.
