Additionally, a solar-powered linear move sprinkler irrigator has been developed for precision agriculture and low energy consumption purpose, but its PV configuration strategy needs to be optimized. A PV system configuration method was put forward in this study according to the seasonal power requirement of sprinkler. Two indexes, namely the loss of power supply probability(LPSP)and the energy excess percentage(EXC)were selected as the constraints, and the minimum cost of life cycle cost(LCC)was specified as the objective function. By means of the meteorological data in Yangling, the PV system configurations of driving and pumping units were optimized. The optimal tilt angle of the PV panel is around 15¡ãin Yangling and 12 PV modules and 3 battery groups can meet the power requirement of a 4-day irrigation cycle. This method can be used in PV system design and optimization of linear move sprinkler irrigation, and it provides a reference to the application of solar energy in agricultural machinery. ª¤
