Each type of solar power plant works at its own temperature level, and then requires an appropriate storage medium. This is particularly true for the direct steam generation plants, where a Phase Change Material (PCM) is needed to store latent heat when the steam is condensed to water at constant temperature (Laing et al., 2011).

OverviewHigh-temperature collectorsHistoryLow-temperature heating and coolingHeat storage for space heatingMedium-temperature collectorsHeat collection and exchangeHeat storage for electric base loads
Where temperatures below about 95 °C are sufficient, as for space heating, flat-plate collectors of the nonconcentrating type are generally used. Because of the relatively high heat losses through the glazing, flat plate collectors will not reach temperatures much above 200 °C even when the heat transfer fluid is stagnant. Such temperatures are too low for efficient conversion to electricity.
