OK, so first off, I am in no way an expert in these matters but I don't know how many panels would be required to run a house and I am (I think) smarter than the average leo regarding such matters, (I am in the trades) so I don't think that in of itself is going to raise suspicion. May I suggest starting out with a truncated version of the final install and make sure that the utility co. isn't going to come by to make sure of the install procedures. Also I would make sure that the install is proper in fact prior to startup with plants I would invite whoever would take issues with the installation, (inspectors of any nature) over and get them satisfied that the install is proper. They certainly will be interested in it at some point and you don't want them there after you have plants. You can always add to the system after all inspections hAVE TAKEN PLACE. dAMN!! How about additional wind energy? Then you will just appear to be yet another alternative energy nut. God knows there are so many of that ilk as to not arouse suspicion. Smell is going to be a big issue and I would not wait untill you have 1500 plants blooming to figure that one out.
Good luck!!
