Switzerland’s New Regional Forecasts Boost Swiss solar power forecast Transparency
The Swiss Solar Energy Dashboard has launched a significant update, introducing new solar power forecasts for 26 regions across Switzerland. This enhancement, managed by the Swiss Federal Office of Energy (SFOE), adds a new layer of granularity to its existing national and regional electricity supply and demand data, marking a major step forward in the country’s renewable energy transparency and planning.
Key Features of the Enhanced Dashboard for Swiss solar power forecast
Announced on October 31, 2025, the update provides both grid operators and the public with unprecedented insight into solar energy generation. The key additions include:
- Daily Regional Data: The dashboard now displays daily solar power production data for each district in Switzerland, offering a localized view of energy generation.
- Five-Day Hourly Forecasts: A highly detailed five-day forecast with hourly resolution is now available. This feature is crucial for short-term planning, allowing for more precise management of the electricity grid and better anticipation of supply fluctuations.
The Technology Behind the Swiss solar power forecast
The accuracy and reliability of these new forecasts are built on a sophisticated combination of data science and diverse information sources. The system, developed in collaboration with the Swiss Data Science Center (SDSC), leverages advanced artificial intelligence to process and analyze data from multiple streams:
- Official registries like Pronovo (the Swiss PV registry) and the Federal Register of Buildings and Housing (RBD).
- Advanced 3D building models and aerial imagery from Swisstopo. AI algorithms analyze this imagery to detect even unregistered PV systems, ensuring a comprehensive dataset.
- Meteorological data from trusted sources like Copernicus and MeteoSwiss.
This powerful data fusion provides a complete picture of the country’s solar infrastructure, from the solar panel manufacturing process that creates the panels to their real-world energy output. All this information is made publicly available as Open Data, fostering further research and innovation.
Purpose and Broader Implications of Swiss solar power forecast
The primary goal of this enhancement is to empower stakeholders across the energy sector. For electricity grid operators, the detailed forecasts are invaluable for balancing supply and demand more effectively, ensuring grid stability as the share of variable renewables grows.
For the public, researchers, and policymakers, the dashboard offers a clear tool to monitor solar energy trends and support Switzerland’s energy transition. This commitment to data transparency places Switzerland at the forefront of renewable energy management, a development tracked in publications like the Global Solar Report.
This initiative also serves as a compelling model for neighboring countries like Germany. For German homeowners and tenants participating in the Energiewende, access to similar localized and predictive data could enable smarter energy consumption. Imagine being able to schedule charging for an electric vehicle or the use of high-consumption appliances to coincide with peak solar production, reducing strain on the grid and potentially lowering energy costs. Switzerland’s approach demonstrates how open data can directly support both national energy goals and individual consumer choices.
A Brighter, More Predictable Solar Future with Swiss solar power forecast
The updated Swiss Energy Dashboard is more than just a data platform; it’s a critical tool for navigating the future of renewable energy. By providing detailed, reliable, and accessible solar power forecasts, Switzerland is not only improving its own energy planning but also setting a new standard for transparency.
