Do you know how expensive it is to launch shit into space (payloads, much less shuttle missions)? There's also degredation due to solar radiation and particle bombardment to consider. Read the wiki article here, it pretty much lays out the launch costs: http://en.wikipedia.org/wiki/Solar_p...e#Launch_costs
Do you know how difficult space power satellites would be to service compared to ground solar farms, because of the above launch costs?
Not trying to dispell the notion of SPS here. It really is a great idea and will probably be how the Earth will be powered, perhaps a century from now. But with launch costs the way they are now and no cheaper/better fuel solutions than LOX/LH2 and Hydrazine, it's going to be a while before this is feasible.
