Global radiation benchmark - Meteonorm is among the leaders
In the IEA PVPS Task 16 benchmark of satellite and model-based solar radiation databases, Meteotest’s Meteonorm time series ranked second overall, outperforming most competitors. The independent validation confirms the high accuracy of Meteonorm’s corrected satellite data, especially in Europe, strengthening its credibility for solar resource assessment in project development and energy yield studies.
«Oversize me»: Optimizing PV production
Meteotest, in collaboration with Clean Power Research and the State University of New York at Albany, conducted a study on the optimal sizing and operation of PV and battery systems for Switzerland’s future renewable electricity supply. The study found that by overbuilding PV capacity to about 40 GW and accepting 10–20% curtailment, electricity production costs could be as low as 0.06–0.08 CHF/kWh, significantly reducing reliance on seasonal storage and imports while ensuring security of supply.
Storm Analysis Mast Fall Albulapass
After the Vaia storm caused the collapse of four 380 kV transmission towers at Albulapass, Swissgrid commissioned Meteotest to analyze the extreme wind event. Using high-resolution turbulence modeling, Meteotest quantified the wind loads on the structures, providing insights for the design and resilience of future power lines against severe weather.
City of Zurich can increase solar power by a factor of 7 by 2030
Meteotest and NET Nowak Energie & Technologie AG assessed the photovoltaic potential on roofs in the city of Zurich, identifying a total production potential of 487 GWh per year. Considering spatial competition, structural limitations, and heritage protection, the study outlines realistic expansion scenarios achieving up to 207 GWh annually by 2030, equipping the city with actionable data to meet its climate goals.
Lightning data – cooperation with Météorage
Meteotest entered a partnership with Météorage to integrate real-time European lightning detection data into its extreme weather portfolio. This enables combined hail, lightning, heavy precipitation, and wind services for industries such as insurance, energy, and transport, enhancing risk management and operational safety.
