Solar Imbalance
The Normalized Solar Production Index measures the average monthly solar electricity production in Belgium. It reflects the solar performance of a given month, regardless of the total number of panels in operation. In practice, it shows whether a month was “sunnier” or “less sunny”, making it possible to compare months within a year and across different years.
