there are four modules connected in series and parallel combinations. The panel is fixed at a tilt angle of 39◦south and uses the DC to DC buck-boost zeta converter with the optimized 5 × 7 FLC-coupled Hopfield NN based on the MPPT controller [21]. The converter setup includes a MOSFET switch, driver circuit, voltage and current sensor circuit, battery load bank and a personal computer with the code composer studio software downloader and a DSP board.
