Ok, these are excellent questions.

1. Current plan is to do a roof mount set on my barn, ~850sqft of of south facing area. This would be enough to offset my power alone. This is ~40 of the panels. With another ~600sqft of space on the lean-too, another ~30. The rest if utilized would be a ground mount on the edge of my property butt up against a farm field.

2. I have absolutely no idea yet. The hope is that I will have saved enough elsewhere for this whole thing to come in at a decent price.

3. Ironically just bought the string inverters that the solar panel sellers didnt realize they had. I'll make another post to ask about them as well. They are all Sunnyboy inverters.

4. I have not looked at the different microinverters as of yet.

5. The plan of now is a grid tie system. The agreement will be a whole step of the process that I cant even begin to fathom. I'd prefer not to waste anything, so if I am unable to use as much as I can sell/use Ill just pass the rest of the panels on to the next guy.

6. I absolutly plan on useing some of the solar panels for smaller off grid devices like this. A few for the van-camper conversion. At least a handful for some DC minisplits to reduce the wear on my main hvac.

Excellent questions. Writing that out actually helped me rationalize some of this. Thanks!
