LSTM based Model for Weather-based Solar Irradiance Prediction for Long-Term PV Energy Planning

Published in 19th IEEE International Conference on Industrial and Information Systems (ICIIS 2025), 2025

This study proposes a deep learning approach using LSTM networks with attention mechanisms to reconstruct missing solar irradiance data from long-term meteorological records, enabling accurate long-term forecasting for photovoltaic (PV) systems. The model outperforms conventional LSTM methods, achieving high accuracy in case studies from Colombo and Hotevilla, thus supporting improved solar energy planning and investment decisions.
