Smart Forecasting of Solar Energy Radiation Using Machine Learning and Deep Learning

Solar Energy Radiation

Project Overview

This project, called “Solar Energy Radiation Prediction”, is all about using real-time weather data to predict how much solar radiation we’ll get. It uses both machine learning and deep learning methods to make the predictions based on stuff like temperature, humidity, wind speed, and direction. This is super useful for things like managing energy, farming, and other green energy systems.The dataset has about 4 months of sensor data, and the main thing we’re trying to predict is “Solar Radiation.” The idea is to build models that can guess future radiation levels using regression techniques.
