In this paper, a method of designing an optimally arranged solar array for converterless matching to a known linear load is proposed and compared to the classical Maximum Power Point Tracking method. Long-time performance of both methods is examined for three common types of loads under real weather conditions. Test results indicate that only in case of a pure resistive load the Maximum Power Point Tracking-based solar system advantage is undisputed. In case of a load represented by a voltage source with internal resistance, the long term energy productions of the system employing a practical Maximum Power Point Tracking operated converter is on a par or lower than the converterless system energy yield.
