For simply running a fan you might look into DC fans and eliminate the inverter, its cost and efficiency tax. One of Ghurds [long time member] controllers could easily handle the control aspect.
Your .42 anmp load at 120 volts will be about 50 watts plus efficiency losses 24/7 and no way a single 85 watt panel will stay ahead of that to start.
Just after thinking it over some.
Good luck sorting it out.
