The performance of solar pump controller can be broadly categorized by a Simulink model. Solar DC Pump consists of solar PV Modules, solar DC controller, and submersible DC pump. Solar cells have nonlinear I-V characteristics and output power depends on solar isolation Level and ambient temperature. Due to mismatch of source and load, efficiency gets decreased. So to extract the maximum power to load from PV panel MPPT is implemented in the Cuk regulator using PWM and Microcontroller. The proposed design optimizes the solar power System to deliver the maximum power to load from source and is presented in the developed Simulink model. This model acts as a prototype for designing Solar DC pump of required rated capacity. Evaluation, design & analysis of PV panel characteristics, modeling of Cuk regulator and DC pump motor are demonstrated using Matlab Simulink model
