Solar Powered Pump Controller for Agricultural Application: Design, Topology and Algorithm

Abstract

Abstract: This research paper presents the design and application of a solar pump controller specifically tailored for agricultural purposes. The controller is developed with the objective of harnessing solar energy efficiently to power irrigation systems in a sustainable manner. The design process involves careful selection and integration of key components, such as solar panels, inverters, and control circuitry, to ensure optimal performance. The controller typically includes a maximum power point tracking (MPPT) algorithm, which enables it to extract the maximum power from the solar panels, even under varying weather conditions. Safety mechanisms are also incorporated to safeguard the system against voltage fluctuations, overcharging, and other potential risks. The application of the solar pump controller in agriculture offers numerous advantages. By eliminating the reliance on grid electricity, it reduces operational costs and contributes to environmental sustainability. The controller enables precise control over water delivery, thereby enhancing irrigation efficiency and conserving valuable water resources. Moreover, it enhances system reliability and longevity by preventing damage caused by electrical irregularities and voltage fluctuations. Extensive field tests were conducted in agricultural settings to evaluate the performance of the controller under various conditions. The results demonstrate significant energy savings and improved crop yield, highlighting the optimized water management facilitated by the solar pump controller. Overall, this research contributes to the development of a reliable, cost-effective, and environmentally friendly solution for agricultural irrigation systems.
