I am looking at getting a solar grid system soon. Problem I think is worth asking about is my house doesn't face east-west, it's north-north west direction.
The largest space on the roof (house is a rectangle shape) is about 12 meters long, but that side of the roof see's morning sun about 1.2 hours after sunrise (no trees in the way), around 2:30pm-3pm a shaddow begins.
So, with the current scheme with REC's must panels be installed on the roof or can I make use of the large yard I have and get the panels mounted on a frame which I would have positioned to follow the sun all day. And would it be worth looking into a mounting design that allows the panel position to tilt as the day progresses. I have no idea about cost for such a thing.
I had one installer mention I only have the space to make up a 2.6kw system on the roof, but I want to fork out for a 5kw system. He did mention many inverters have one input not two or more, so if some panels lose light the other don't work as good or at all.
