Short - Term Solar Radiation Forecasting for Adaptive Solar Cell Using a Hybrid D-FFNN Model

Hikmat Oka Kusuma, Unit Three Kartini, Bambang Suprianto & Rifqi Firmansyah · Journal of Energy Research and Reviews · 2025

Variations in the value of solar radiation affect the efficiency of solar panels and thus cannot be predicted. This causes instability in the generated power and negatively impacts the reliability of the solar power plant. This research formulates the prediction of solar radiatio...
