The best looking spot (from a Google Earth viewpoint) is about 150' SW of the house.
The ground there is about 22 feet lower than the blue area.
But, it seems like it might be the best area,
since (it looks like) there's not much else that's real close in.
There may be some blockage, you just need to find out if it's going to be
too much blockage.
Then there is the also the possibility of clearing some of that blockage by using a high mounted array..
If the array was 10 or 15 feet off the ground, it might get full sun for a longer period of time..
I don't think there are very many 'idea' solar mount locations,
there will always be something that's going to cast a shadow at some point.
I think my backyard mounts get about 3 hours of good sun this time of year..
