i am very new to this, and i have been asked to explain a few times, how the power generated fro the pv panels is used for power around the house,
i.e how does it know to use the power from the pv panel and stop using power from the electricity supplier,
But surely with the inverter being mains fed and no cistern above the panels it can't possibly be graviity fed, it must be an unvented system? What are you smoking Julian?
Most Aussies are on overhead mains feed so the panels go in the basement and everything's fine. Installs are expensive though as they have to factor in all the mirror glass to get the sun in.
