Ignoring economies of scale for the moment, this will never be as cheap (assuming an equal cost per kW) as having solar on one's own roof. There is a cost in building out and maintaining the grid infrastructure, and that has to be accounted for if the power is generated remotely, even if you own a part of the generation capacity.Off topic, however this why power purchase agreements should be enabled for solar farms. Stick a solar farm out where there are no trees and allow an agreement where a home owner (or even in an apartment or renters) can act like that solar is on their roof.
If you don't have the capacity on the roof for more solar, then by all means go for it - but don't think for a moment that it will work out as cheaply for you as if you have your own panels on your own property.
