An interesting read on the future of solar implementation called "Selfish Solar" where the system is not "gird-tied" but rather "Grid supplemented". You use the solar to charge your massive battery array and have a charger hooked to the grid for those consecutive overcast days to top off the pack.

Basically the power companies hate change...they hate people becoming independent of the grid and are working to hedge their massive infrastructure investment. If we are forced to have power to our homes, then we should be free to choose what happens between that power hookup and our lives. Grid tied solar is NOT the answer to energy independence...selfish solar IS.
