Wissenschaftliche Analysen zu ausgewählten Aspekten der Statistik erneuerbarer Energien und zur Unterstützung der der Arbeitsgruppe Erneuerbare Energien-Statistik Fachbericht Solarthermie

Summary

Germany faces a challenge in accurately tracking the thermal use of solar energy due to poor quality and insufficient detail in current market data compared to photovoltaics, hindering effective policy steering. This report validates and further develops the methodology for determining the installed solar collector area and associated energy yield in Germany, based on available data sources and recommendations from the International Energy Agency. The study, completed in November 2024 and published in October 2025, provides scientific analyses, identifies current market trends, and offers recommendations for adjusting the IEA methodology for future solar thermal energy accounting.
