During the determination of optimal tilt angle of fixed grid-connected photovoltaic (PV) array, two factors, i.e., the annual generated energy and uniformity of illumination radiation, should be considered simultaneously. A multi-objective optimal tilt angle of PV array model, in which the maximum annual irradiation amount and the minimum cumulative departure of the irradiation are taken as objectives, is established. The established model is solved by interactive objective decision-making method based on satisfaction degree of objectives and overall coordination degree to interact the decision-maker’s subjective wishes with the system in real-time, so the computational efficiency is high. The reasonability of the established model and the reliability of the proposed interactive multi-objective decision-making are validated by calculation example.
