Preiskanibalisierung und negative Strompreise im Solarmarkt

3 verified sources

Definition

Solar capture rate (actual revenue vs. market price) collapsed from 98% (2022) to 54% (2025). In May-June 2025, monthly capture rates fell below 0.45, meaning generators received only €0.43-0.44 per €1.00 of market reference price. Negative-price hours exceeded 300 in Q2 2025 alone, with prices ranging from -€64.31/MWh to +€102.56/MWh. Each year, the number of sub-50% revenue days doubles.

Key Findings

  • Financial Impact: €billions in lost revenue: May 2025 capture price €19.97/MWh (37% YoY decline); June 2025 €18.43/MWh (61% YoY decline). Extrapolated annual impact: ~€8-12 billion lost merchant value across 100+ GW installed base at current cannibalization rates.
  • Frequency: Continuous and accelerating: Capture rates fell below 50% 11 times (2022) → 31 times (2023) → 63 times (2024). Doubling annually.
  • Root Cause: Unplanned overbuild of solar capacity relative to grid demand; no dynamic pricing or demand-response mechanism to balance supply-demand; legacy fixed-tariff EEG contracts prevent price signals reaching operators.

Why This Matters

This pain point represents a significant opportunity for B2B solutions targeting Solar Electric Power Generation.

Affected Stakeholders

Merchant solar operators, PPA-exposed projects, Grid operators, EEG account administrators

Related Business Risks

EEG-Kontenausfall und Bundessubventionsdrain

€7.3 billion injected in first 6 months of 2025; €18 billion cumulative 2024 shortfall; projected €10+ billion annual federal spend to balance EEG account.

Netzüberlastung und Einspeiseverzicht durch Überkapazität

Estimated €500M-1.5bn annual output loss from curtailment (5-15% of marginal solar production during peak season); no direct revenue during forced shutdown periods; grid connection fees remain payable.

Historischer Tarifschock und Industrievernichtung (2012-2014)

€10+ billion in destroyed market capitalization; 80,000 jobs lost; €731 million damages claim by SolarWorld alone; estimated €5+ billion in lost tax revenue and pension obligations.

Verzögerter Schadensfall-Auszahlungsprozess durch manuelle Dokumentation

€2,000-€8,000 revenue loss per incident; 30-90 day payment delay typical

Bußgelder und Versicherungslücken durch fehlende Nachweise bei Schadensfall

€500-€5,000 per compliance failure; €200-€1,000 per audit penalty; 5-10% of claims denied for documentation compliance failures

Manuelle Schadensfall-Dokumentation als Kapazitätsengpass

15-40 hours labor per claim at €45-€65/hour = €675-€2,600 labor cost per incident; 2-4 incidents annually = €1,350-€10,400 annual capacity loss
