Relatively easy tech is temporary hydrogen storage. Of course hydrogen has poorer efficiency than batteries, but if all batteries are full, excess energy could be converted to hydrogen, stored, and converted back to electricity when no solar is available, and batteries are empty. Efficiency roundtrip with current tech is roughly 70%.
