I am struggling to find sufficient roof area for 34 310 Q cells given set back requirements or for Panasonic 330s. We have a lot of land for a ground mount with a couple of areas acceptable esthetic wise (one area close to a meter and one area about 150 feet away from a meter). But ground mounting is more expensive, but I understand it is more efficient given the ability to set at the optimum tilt and perhaps adjust for seasons. My question - is ground mounting so much more efficient than a roof mount that I could get by with fewer panels- e.g., 30-32 panels instead of 34 on the roof, which could make up some of the additional expense for ground mounting?
Not a fair question, I know, but I am trying to educate myself as much as possible for those times I talk to the contractors making proposals. Any help is appreciated.
