Appart from using solar power to melt salt as a energy storage solution, you also have water cooled solar panels that store that heat as warm water.

    These are cool because they add efficiency by both preheating your water for your water heater and help cool the photovoltaic cells so they can run more efficiently too. Downside of course is that there's now a bunch of water pipes on your roof too
