Increasing generation of renewable energies are good for the environment, however bring challenges for electricity grid stabilization. Therefore, forecast- ing of such energies becomes very important. This research conducts research on forecasting solar power using a LSTM neural network. Data from BSRN with a time frame of 1 min is used to built a model. Humidity, Dew/Frost point, Station Pressure, month number and day number were found to work best to predict solar radiation. Further the tuning, evaluation and testing of the model are extensively discussed. An analysis of power spectral density of the predicted values shows that there exist difficulties in predicting in low frequencies. The LSTM model shows overall promising results and can be used for various data sizes.
