太阳能光伏提水系统与传统提水系统成本对比分析

The Comparative Analysis on Costs of Solar and Traditional Water Pump Systems

光伏提水是以太阳能作为动力,带动水泵提水的应用系统,是缺水、缺电地区解决农业灌溉问题及促进农业生产发展的重要方式。提水成本是其技术推广时的重要指标,通过分析与对比光伏泵与各类提水系统的提水成本可知,光伏提水相对于市电和柴油取水,设备购置成本较高,但运行成本明显较低,最终使得多年分担的吨提水成本较低,相关数据可为推广光伏提水提供依据。

Solar water pump system utilizes solar energy to lift water,which can help solving the irrigation problems especially in power-shortage areas and raise the local agricultural production.The cost of water pump system is an important factor in technological promotion.The comparative analysis presents that solar water pumps had higher equipment purchase cost and considerably lower operation cost per year when compared with grid power water pumps and diesel pumps.When the total cost is apportioned t?years,the annual cost of unit water lifting for solar water pump system is much lower,which can support its promotion.
