Abstract

The increasing demand for energy and the environmental impact from the excessive use of fossil fuels has increased the interest in the renewable research. Solar energy is increasingly becoming an area of interest to researchers due to its abundance source and accessibility. This can be achieved by utilizing photovoltaic (PV) panels. Nevertheless, due to PV nonlinear characteristics, maximum power point tracking (MPPT) algorithm are applied. Many MPPT techniques and improvement have been reported in the literature. In this paper, the impact of temperature and irradiation on the performance of proportionality constants in both fractional open circuit voltage (FOCV) MPPT and fractional short circuit current (FSCC) MPPT techniques are explored. Normally in these algorithms the irradiation effect is solely considered. However, the obtained results show that the value of these constants can be re-tuned for better energy harvesting when both the temperature and the irradiation change.
