Solar plant i.e. liquid-containing thermal solar plant, has expansion and pressure holder part attached to bypass unit, where holder part is connected with solar circuit when vaporizing liquid in collector
The plant (1) has a pump (10) arranged in a portion of a solar return line (9), which is extended between an exhaust opening (7) and the pump in conveyance direction. An expansion and pressure holder part (17) is attached to a bypass unit (15) such that a positioning device (16) is arranged in a control link in a passage position when an operating condition detection unit detects a stagnation operating mode. The expansion and pressure holder part is connected with a solar circuit when vaporizing liquid in a collector (2) by the bypass unit.
