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...
