Solar Thermal Roof Potential in Saarland Municipalities

A map service from the state study 'Wärmewende im Saarland' presents the usable annual yield for rooftop solar thermal potential. The layer shows this potential divided into classes in megawatt-hours at the municipal level. The data is provided by the Bundesamt für Kartographie und Geodäsie and was last updated on 2026-03-19.

Use Cases

• Identify municipalities with high solar thermal potential based on the annual yield classes.
• Plan regional energy transition strategies based on the mapped rooftop potential.
• Prioritize areas for solar thermal infrastructure investment based on the municipal-level data.
• Model renewable energy supply scenarios for heating based on the quantified annual yield.

Strengths

• Data is derived from a dedicated state study on the 'Wärmewende' (heat transition).
• Potential is quantified in usable annual yield (MWh) and categorized into classes.
• Spatial resolution is at the municipal level, providing administrative granularity.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• The description metadata is limited; actual data quality requires manual inspection.
