No, I don't think so. Provided that you can afford this setup without hardship, I think there are many positive benefits.

As dweste said, it depends on your motivation. It might be a smaller environmental footprint, it might be greater self-sufficiency. Personally, I find that these two dove-tail rather nicely as long as practical goals are not overshadowed by the annoying self-righteousness exhibited by the fringe/fruitcake zealots.

I observe that you are spending your money on efficiency first and generation second. This is the right path IMO -- money spent on the consumption side always gets more bang for the buck. Efficiency also reduces footprint across the board, and puts a greater degree of self-sufficiency within reach (even if it's not 365 days a year).

As well, in the months where grid power is your primary source, you now have the solar rig as a backup in the event of storms or outages. PV panels generate power even on overcast days, and that slow trickle adds up. You may just find that with cooler weather (less cooling needed) and trickle charging from the panels, you won't need grid power all the time even in winter. Or, you may choose to run a laptop or a few desk lamps using the reduced solar output, to partially offset the grid power needed for the freezer.

So, if you can otherwise handle the cost, I say do it.
