Abstract
The proposed paper highlights the performance analysis of the effect of vibrations on the flexible solar panel. The vibrations have been produced by vibration generator embedded on the rear side of the flexible solar panel for testing purpose. The performance of the proposed system has been analyzed in terms of voltage (V), current (mA) and power (mW) obtained from the solar panel. The proposed vibration generator comprises of Lead Zirconate Titanate (PZT) material transducers having the internal capacitance of 25 nF and astable multivibrator has been used for controlling the frequency range of the vibrations for the piezoelectric transducer. The piezoelectric transducers have been connected in parallel in order to maintain a constant voltage across the system. The proposed setup analyzes the change in voltage (V), current (mA) and power (mW) when vibration of different frequencies is fed to the panel. The power variation of 1.898 mW has been observed for the frequency variation of 640 Hz. The results have been analyzed for the frequency range of 40 to 680 Hz. The maximum and minimum power output of 15.818 mW and 13.92 mW has been obtained at 360 Hz and 120 Hz, respectively. The maximum voltage and current output levels have been attained at 360 Hz and 560 Hz, respectively. The formulated results have been analyzed graphically for the voltage (V), current (mA), and power (mW) with respect to frequency (Hz).
