Abstract. For sensible thermal energy storage (TES) in liquids in the temperature range from 250 °C to 550 °C, a mixture of 60 wt% sodium nitrate (NaNO 3) and 40 wt% potassium nitrate (KNO 3 ), known as Solar Salt, is commonly utilized. At the time of writing, TES technology for concentrating solar power is the major application.

1) Battery Storage. One of the most common and effective ways to store solar energy is through batteries. Batteries store excess energy generated during sunny periods for use during cloudy days or at night. Lithium-ion batteries, in particular, have gained prominence due to their high energy density and long lifespan.
Temperatures can be hottest during these times, and people who work daytime hours get home and begin using electricity to cool their homes, cook, and run appliances. Storage helps solar contribute to the electricity supply even when the sun isn''t shining. It can also help smooth out variations in how solar energy flows on the grid.
