[QUOTE="daveg, post: 551665, member: 37649"] Hi I am interested in this setup as I am looking at a similar installation - total of 8kWp split evenly between E & W facing rooves. From the research I have done it seems the E-W configuration reduces the peak power by about 25% so for my system a 6kW inverter looks ok. For your 8.7kWp installation this would give a peak output of 6.525kW and depending on the shading maybe a bit lower so a 6kW inverter may not be too far out and only have to clip for a short time around mid-day on the sunniest days. This is an interesting article about E-W designs:- [URL unfurl="true"]https://ratedpower.com/blog/solar-panel-orientation/[/URL] Warning - i am new to solar so may be talking rubbish. [/QUOTE]
