We’ve considered it because our property comprises of two buildings, the house and the garage with rooftops of different orientations and as such we’ve often considered putting panels on two of the rooftop surfaces to benefit from the daylight as much as possible. I reckon the inverter and battery could go in the garage. I quite like the whole engineering aspects of it too.
Build it!
Someone at work has a similar layout, but he is not convinced by the economics. A more complicated install will cost more, but I don't think people do it just for the money. That said, if we keep living here then it will save me money when I'm retired.
That’s the thing if we can save tomorrow then we can enjoy more of the money we’ve saved when younger; mind you it’s a balance really as round got to enjoy now too!
