In this paper, a densely clustered controllable precision based fuzzy logic algorithm for maximum power point tracking of a high capacity PV panel has been thoroughly developed. Slow transient response time as well as reliability problem of traditional fuzzy logic based MPPT algorithms have been successfully encountered in this paper. A high precision convergence of maximum power point tracking can be achieved with some trade-off between settling time in case where high power PV cell is being used. Performance of the proposed algorithm has been simulated in MATLAB / PSIM using the datasheet of MSX60 standard solar panel module. The algorithm has been written in a compatible mode for microcontrollers.
