It is based on oversizing no-storage PV plants beyond meeting their peak daytime demand, and storing the excess energy as high-temperature heat in molten salts, from which high-efficiency steam turbines can be driven. Grid penetration levels of ~80–95% can be realized with storage capacities of only ~12 h of average electricity demand.
The best panels for commercial use have efficiencies around 18% to 22%, but researchers are studying how to improve efficiency and energy yield while keeping production costs low.
