EXECUTIVE SUMMARY: This study aimed to develop a Simulation of Solar-Powered Pumping System for Irrigation, The study also aims to show that using solar energy as an energy source, it can produce enough power to lift and transfer the water using a submersible pumps as a medium to irrigate farm lands whether it's from an underground water source, deep well, or streams. In solar-powered systems, although this system is relatively expensive, the source of energy is free, therefore, after amortization period, there are no longer operating costs (only the maintenance costs must be considered). To conclude, solar pumps turn out to be a viable long term investment. The study used the descriptive and technical experimental type of research utilizing the researchers of the following discoveries: the smaller the opening of the nozzle, the faster the velocity of the water and the less time it consumes to fill the plastic pot which is backed up by a principle in fluid dynamics called the Venturi Effect and the position of the sun, the temperature and the weather greatly influence the voltage produced by the solar panel and the hydraulic power of the pump. A modified questionnaire checklist and interview was used for the descriptive method of research and to determine the level of acceptability of the Simulation of Solar-Powered Pumping System for Irrigation in terms of functionality, usefulness, safety features and maintenance. The respondents pf the study were 5 farmers (research experts) and 20 students. Weighted mean was used to determine the acceptability of the system in terms of the said criteria and objectives. The simulation of Solar-Powered Pumping System for Irrigation was found to be extremely accepted by the students and very much accepted by the experts in performance in terms of functionality, usefulness, safety feaures and maintenance as evaluated by the respondents and that it can be constructed and completely assembled by locally available materials. This study however is focusing only on solar energy as power source and how to transfer water from one place to another that it does not include instruments that detect pests which are present in crops, sense if the farmland is over watered or under watered and detect the varying weather and calamity. For further study, the researchers recommend to improve the piping system for a more reliable use and to add more features in the system.
