The majority of the population in Kaliwungu Lor Village, Purworejo District work as farmers. The irrigation system in the village generally still uses semi-technical irrigation and rainfed paddy fields. In the dry season, rainfed fields often experience difficulties in producing paddy due to the difficulty of water for irrigation. In 2020, the Provincial Government of Central Java provided assistance in the form of a Solar Water Pumps Systems (SWPS) with a capacity of 11 kWp to irrigate 15 hectares of paddy fields. The system is expected to distribute water from the Kranjang River to agricultural land in Kaliwungu Lor Village during the dry season. This study examines the effect of SWPS installation on the economic conditions of farmers in Kaliwungu Lor Village. The research used a survey method with a quantitative approach. A paired sample t-test was conducted to evaluate the statistical significance of operational cost differences before and after the implementation of the SWPS. The analysis was carried out at a 95% confidence level with a significance threshold of p<0.05. Based on the results of the research conducted, the construction of SWPS in Kaliwungu Lor Village can increase the harvest period for farmers, which was originally 2 times/year to 3 times/year, there are 108 tons/year. In addition, the SWPS reduced operational costs previously spent on diesel fuel for irrigation pumps during the dry season. Farmers saved Rp 37.311.750/per planting period in 2020-2021 and Rp 49.266.000/per planting period from 2022-2025.
