Abstract/Summary:

---

Our work presents a detailed benchmark of eight commercial forecasting solutions for intra-day solar forecasts. The comparison was carried out on a period of six months, from November to May 2021, on seven different PV plants located in different countries of the northern hemisphere. Performance evaluation metrics MAE and RMSE are used in order to analyze the forecasting precision. It is shown that forecasting solar power and accurately taking advantage of satellite images to improve the precision of forecast for small time horizons remains challenging.
