The invention provides an intelligent control method for a solar energy system. A solar heat collector system comprises a heat collector, wherein the heat collector comprises a heat collecting pipe and a water tank; the heat collecting pipe comprises a heat absorbing end and a heat releasing end, and the heat releasing end is arranged in the water tank; a water level meter is arranged in the water tank, and an outlet pipe temperature sensor is arranged on an outlet pipeline of the water tank; an inlet pipe valve and an outlet pipe valve are respectively arranged on an inlet pipe and an outlet pipe of the water tank, and the water level meter, the temperature sensor, the inlet pipe valve and the outlet pipe valve are in data connection with a central controller; the central controller controls the size of the opening degree of the inlet pipe valve and the outlet pipe valve according to the temperature measured by the temperature sensor and the water level measured by the water level meter. The method automatically controls multiple parameters of the solar energy system, realizes intelligent control for the solar water temperature, and therefore improves the using intelligentization of the solar energy system.
