L Limited access to electricity in rural areas is still a major obstacle in supporting agricultural activities, especially in irrigation systems that require stable and environmentally friendly energy sources. kamurang village, tirtamulya district, karawang regency, is one of the areas that has not been fully reached by conventional electricity networks. therefore, this study was conducted to design and analyze the performance of an off-grid solar power plant (plts) with a capacity of 200 wp as an alternative energy solution for agricultural irrigation in 120 m² of spinach fields. the research method includes designing a plts system consisting of two 100 wp solar panels, a battery, a solar charge controller, and a 60 w electric pump. performance tests were carried out for one week by taking data every 30 minutes from 09:00 to 15:00, to measure output power, solar radiation intensity, and system efficiency. the results showed that the plts was able to produce an average power of 85.8 wh with an average insolation of 770.81 w/m² and a system efficiency of 111.1%. in terms of economics, the initial investment of rp4,355,500 and annual operating costs of rp43,555 resulted in a 10-year life cycle cost of rp4,391,178. these results show that the designed solar power plant is technically and economically effective, and feasible to be applied as a solution for agricultural irrigation in areas that have not been reached by pln electricity.
