In November 2018, Spirit installed a domestic on roof PV system in Surrey. With the available roof space a 3.965kWp system was able to be installed, with the array consisting of 13 Q-Cells 305W panels. The inverter is sized to match the peak power and for this system a Growatt 3600W MTL inverter is used. The panels are orientated 20 degrees from south and pitched at a 10 degree slope to maximise irradiance. The slope angle and spacing between each row of panels ensures that shading from the other panels is kept to a minimum or zero. The loss factor arising from shading is assumed to be zero for this system. The expected output is a little over 3,500kWh per year, equating to predicted annual CO2 savings of 1,836kg.
