This paper demonstrates the statistical analysis of a receiver’s voltage outputs from laser beam alignment adjustments in a laser-based wireless power transmission’s experimental photovoltaic cell characterization test. The purpose of the experiment is to investigate how the voltage outputs of the photovoltaic cell vary in response to changes in the X-axis distance between the center of the transmitter’s laser beam and the center of the receiver’s vertical multi-junction photovoltaic cell, with constant laser power supply wattage at 𝟏. 𝟒 𝑾 and constant driver current at 𝟐. 𝟎𝟖𝑨. The experimental data collected from the LPT configuration is used in statistical analysis involving normality tests, hypothesis testing, regression analysis, and ANOVA test. All empirical data is collected and analyzed through a combination of computer programming for voltage sensor readings, optical and electrical engineering between primary hardware components, the voltage sensor, and high-intensity laser beaming subsystems, and integrated data logging and graphical representations through EXCEL’s Data Streamer using a constant time interval of 𝟏𝟓𝟎 𝒎𝒔. The procedure accomplishes a replicable method for field sensor data logging as a preliminary for the transmitter’s optical gimbal motor controls of the X and Y directions of the laser beam collimator holding the fiber optic cable. For statistical models and computational calculations, Minitab 18.0 Statistical Software is used.
