Water pumping with solar power is not very popular in Sri Lanka mainly due to their poor performance despite having most favourable climatic conditions .for the same. The controlled tests carried out with a typical solar water pumping system indicated that photo voltaic modules consistently attained the performance levels specified by the manufacturers, while the pump performed at noticeably lower levels. Further, the high initial cost of solar water pumping systems when compared to alternative sources is a major obstacle in the widespread use of this renewable energy technology.
