Show me a heatmap of negative electricity price hours by hour-of-day and month for Germany in 2024

The solar diagonal is unmistakable. Negative prices are almost exclusively confined to the 10:00–17:00 window — precisely when German solar generation peaks. Outside those hours, the market clears positively year-round. In July, there was a 45% chance of a negative price at 13:00–14:00 — nearly one in two afternoons. May and June are nearly as intense. Winter negatives shift entirely to overnight (00:00–07:00) — surplus wind, not solar.
