It will work fine if correctly designed and you use appropriate wire. You'll need the batteries/inverters etc to be with the panels, so that the connection back to the house is AC. Trying to provide appropriate wire to handle 8500W DC over that distance would not be practical at all. Obviously you'll need to provide a weather-tight enclosure for the gear, perhaps climate controlled depending on location and batteries...
I realize this is an old post, but I want to stop the misconception that a/c is better over a distance then d/c. Its irrelevant and only related to the voltage drop and too many amps running through the wires. For instance, there are charge controllers on the market that can take 600 vDC and charge battery banks of any voltage you desire, 12, 24, 48 etc. If you connect your panels in series to 600 v D/C, your going to have 5 times the efficiency through the wires as you would 120 volts A/C. The ONLY reason that a/c is used in power lines is due to the magic ability of transformers to step up and step down the voltage. Transformers do not work like that for DC, but as technology increases our options are getting better!
