It's actually a code requirement to ground the panels at separate buildings.
The reason is to establish ground. I know that you are "carrying ground" back to the main service panel, via the wiring, but the ground reference at both locations will now be the same.
Every single transition point along the distribution route from the 345KV output of the turbine generator, to your light switch, is always referenced somehow or the other to earth ground
