Abstract
This chapter discusses the assessment of comprehensive technoeconomic performance by simulation and experimental values over a 1-year period for four distinct solar photovoltaic (PV) systems mounted at the Indian Institute of Technology Kharagpur in West Bengal, India. The chapter includes the field system description and their user interface followed by detailed modeling of PV, inverters, and the sun tracking (ST) systems in MATLAB/Simulink. It then explains the evaluation of the overall system performance for all four configurations using technical performance indices (energy yield, capacity factor, performance ratio) and economical performance indices (payback period, net present value, levelized cost of energy) defined by IEC Standard 61724. The impact of inverter technology and ST system is thoroughly discussed using the field data of one full seasonal variation. The technical dominance of Dual Axis Micro Inverter-based solar PV system and economical superiority of Dual Axis String Inverter-based solar PV system over other configurations is validated through simulation and experimental field results.
