Özet

Photovoltaic systems have been a prominent option as an additional energy source for vehicles. Maximum power point trackers (MPPTs) should be used to increase efficiency and power output of solar panels under changing environmental factors. There are several different algorithms in the literature developed for maximum power point tracking. However, energy performances of MPPT algorithms are not clarified for vehicle applications that cause rapid changes of environmental factors. In this study, three popular MPPT algorithms, i.e. P&O, IC and OC, are compared at real ambient conditions by couples. For comparison, PV modules are mounted on a moving platform designed to simulate insulation received by solar systems on a moving vehicle. Experimental results obtained from comparison of algorithms by a motion loop are presented and discussed.
