Yes, but does it make sense?
I would think the obvious question would be, does buying/installing a solar panel system make any sense for the individual, grid tied house? Given the current price for the hardware and labor vs the actual value of the electricity produced, is there any gain from the solar electric system?
In the US, at least, the commercial solar PV power plant is driven by government subsidies and large loan guarantees. Maybe if we had electricity prices as high as some "green" countries it would make sense. Er, or not.
Where does the power come from when clouds move in? Quick response gas turbines? What do those cost, and has that been figured into the system cost of "going solar"? I have a feeling that "big solar" is going to be a self limiting enterprise.
