Correct, solar not needed. Depending on your battery capacity and usage patterns you could enroll in one of the plans that lets you pay cheaper rates off-peak to charge your batteries from the grid, and then power your house off the batteries during peak times. Some places this makes a lot of sense - the spread here (between off-peak, flat rate, and peak) is not favorable enough to make it interesting though, as far as I can tell.
