The invention relates to the field of steam generators, and discloses a steam generator system. The steam generator system comprises a water source, a solar thermal collector, a heat pump system and asteam generator which are connected in sequence through pipelines; and the water source is subjected to primary heating through the solar thermal collector and subjected to secondary heating throughthe heat pump system in sequence, and then enters the steam generator to be converted into steam. According to the steam generator system provided by the invention, the water is subjected to primary heating through the clean environment-friendly solar thermal collector so as to reach the temperature of a water inlet of the heat pump system, and then, the water is subjected to secondary heating through the heat pump system high in energy consumption ratio so as to reach the temperature of a water inlet of the steam generator. The steam generator system effectively utilizes solar energy, energyresources are saved, meanwhile, heating is conducted through the heat pump system, the high energy consumption ratio is achieved, in addition, no pollutant is generated, and accordingly, the energy consumption ratio and the environment-friendly performance of the steam generator system are comprehensively improved.
