An accurate solar PV power forecasting method is significant since it is a crucial component of the planning process. Therefore, a more accurate technique must be applied to predict the power generation of a solar PV system in pursuing an economical operation.
In certain conditions, local site solar irradiance measurement is more accurate compared to other methods. This is the reason why several studies have focused on improving the accuracy of measurement for solar irradiance at a local site.
The analysis indicates that solar forecasting is 98% accurate using one year's worth of data for solar radiation. Gutierrez-Corea et al. (2016) studied the application of the ANN algorithm for short-term prediction (between 1 hour and 6 hours) of power generation.
The finding is consistent with Kashyap et al. (2015) who found that a good ANN model with quality data input can increase the accuracy of solar power generation forecasting. Their test result showed an RMSE error between 10% and 15%.
The review revealed that proper handling and calibration of solar irradiance instruments can improve forecasting accuracy. This finding indicates that reductions in instrument errors measuring the weather parameter can increase solar forecasting accuracy. 1. Introduction
The ANN solar irradiance forecasting is produced with accurate results compared to individual models. However, the review also revealed that improvement in forecasting accuracy can be achieved through proper handling and calibration of the solar irradiance instrument.
