Solar irradiance forecasting using statistical and machine learning methods
The installed capacity of solar photovoltaic (PV) is continues to rise in the world and Malaysia throughout the year. In Malaysia, the average daily solar radiation is 4,000 to 5,000 Wh/m2, with the average daily sunshine duration ranging from 4 to 8 hours. However, the output of solar energy is lac...

Solar irradiance forecasting is a crucial component in the effective integration of solar PV systems into the electrical grid. The variability of solar energy and the uncertainties associated with solar irradiance predictions pose significant challenges for grid operators and energy planners. This research project aims to develop advanced forecasting methods and methodologies for accurate and reliable solar irradiance prediction, considering the specific characteristics of local weather conditions.
