This standard defines the main terms and definitions of solar thermal power stations (STE) and aims to provide a reference for industry users. Solar thermal power stations usually consist of three main systems: heat collection system, power generation system and heat storage system. Because the components and configuration of a CSP plant depend on the solar collector technology used (i.e. tower, parabolic trough, parabolic dish or linear Fresnel collector technology), some terms do not apply to all types Solar thermal power station, a note has been introduced in its definition for clarification.
