摘要：Agricultural production relies heavily on irrigation, and water pumping for irrigation consumes a great amount of electricity every year in China. Meanwhile, more land in remote areas is barren because of lack of electricity and access to irrigation. Till now, most research works have been focused on the technological aspects of SPV irrigation system, very few studies were reported on economic and financial aspects of the system. The main barrier to promotion and application of SPV irrigation systems seemed the high initial investment. To analyse and clarify the comparative advantages of SPV facilities, the life cycle cost, energy consumption and pollution emission of pump stations powered by SPV, electricity and diesel was calculated respectively through a case study. The initial investment ratio of SPV, electricity and diesel pump station is 12.7:9.3:1, while the life cycle cost ratio of them becomes to 1:1.59:1.88, the SPV turned out to be economical, energy saving and environmental friendly. Policy suggestions on encouraging the construction of photo-electric complementary pumping stations and financial support to water users are put forward to make good use of SPV systems and release the financial burden from the initial investment.
