This page summarizes solar photovoltaic (PV) energy statistics for Belgium. We use quarter hour grid data from Elia, which is corrected with up-scaled measurement data for the monitored capacity. The monitored capacity can deviate from the installed capacity. To ease comparison between different years, absolute and normalized values are shown in tabular format. Additionally two plot visulualize the data. First we show average normalized solar PV energy per hour for different months. This shows that average solar energy peaks around noon, and decreases in the winter period. The second plot shows monthly boxplots of the quarterly solar energy values, extended with the 10th percentile (p10), average (avg) and 90th percentile (p90). We observe that the median solar production is signifantly lower than the average solar production, while the average is significantly lower than maxima and P90 values.
