PERFORMANCE OF PHOTOVOLTAIC SYSTEMS IN SERIES AND PARALLEL CONNECTION: A COMPREHENSIVE RESEARCH STUDY
Keywords:
photovoltaic, series, parallel, current, voltageAbstract
This comprehensive research study investigates the performance of photovoltaic (PV)
systems in series and parallel connections. The study explores the theoretical aspects and
electrical characteristics of these connection configurations, including voltage-current (V-I)
curves, power-voltage (P-V) curves, and maximum power points (MPPs). Experimental
investigations are conducted using a real-life PV system setup solar module. Detailed
measurements of current, voltage, and power are recorded under varying resistance. The
collected data are analysed to compare the performance of series and parallel connections in
terms of system efficiency and power output. The research findings reveal that series connection
yields higher voltages, while parallel connection provides higher currents. Series connection
demonstrates higher overall system efficiency, particularly in low solar irradiance situations. On
the other hand, parallel connection is less efficient than series connection regarding to this
experiment. Overall, this research study offers valuable insights into the performance
characteristics of PV systems in series and parallel connections. The findings provide guidance
for optimizing the configuration of solar modules based on specific environmental and operational
conditions. This contributes to enhancing the efficiency, and power output of PV systems,
promoting the widespread adoption of solar energy as a sustainable solution for a greener future.
