Subject Development of automatic photovoltaic pumping system -

Abstract

     This research objective is to develop a model of automatic photovoltaic water pumping system. Find quality and efficiency of automatic photovoltaic pumping systems and study the user's satisfaction with the use of automatic photovoltaic pumping systems to farmers. The research process was carried out by the development of an automated photovoltaic pumping system. Evaluated by 5 experts and then developed a model for automatic photovoltaic pumping system. And then it's evaluated with a sample of faculty members. 30 students, staff and farmers were acquired by specific selection, collected and analyzed with average statistics and standard deviations. The results showed that experts assessed the level of development as optimal. The total average is 4.68 and the standard deviation is 0.46. The standard deviation is 0.41, and when tested for the efficiency of the automatic photovoltaic pumping system. It has an average of 100, which exceeds the threshold of the hypothesis set, and the sample shows the user's satisfaction with the use of the developed system at the highest quality level. It has a total average of 4.72, the standard deviation is equal to 0.41.

     Therefore, it can be concluded that the development of automatic photovoltaic pumping systems can save time and labor. It creates convenience and eases the burden on farmers to control and turn on and off their water system via smartphone anytime, anywhere, and helps to control the air temperature in a quality way and increase the productivity of vegetable gardens or greenhouses.
