His work bridges standards development, sensor technology, and real-world PV plant operations, with a strong focus on enabling transparent, bankable, and high-performing solar assets.
Soiling: A Performance And Revenue reality
Soiling is still too often treated as a maintenance consideration. In reality, it directly influences how solar performance is understood, reported and defended over time.
At Intersolar Europe 2026, our sessions explore how moving beyond assumed losses toward accurate, representative and long‑term‑stable measurement enables confident decisions aligned to real project requirements and expectations..
10:00 CEST
Precision Weather Intelligence for the PV Market: The new J-Series Compact Weather Stations
Discover the latest upgrades to the Lufft Compact Weather Station series and how they deliver more accurate, reliable, and practical weather data to support PV performance optimisation and system monitoring.
11:00 CEST
Soiling Challenges and Our Solutions
Explore how PV soiling causes energy losses and compare key soiling sensor technologies, highlighting their accuracy, maintenance, and usability trade‑offs.
12:00 CEST
Choosing the Right Pyranometer: A Practical Guide for Solar Professionals
Explore why irradiance sensor selection is a lifetime PV asset decision, and compare key sensor types to understand their impact on accuracy, performance risk, and long‑term value.
14:00 CEST
Introduction to Atonometrics
Explore the evolution of Atonometrics and how bringing leading measurement brands together creates greater value for PV performance analysis and decision‑making.
15:00 CEST
Primer on Performance Metrics for PV Systems
Gain clarity on the IEC 61724 standard series and how PV performance is monitored using meteorological stations and sensors—covering key metrics, common interpretation challenges, and notable updates in the latest revision.
16:00 CEST
Detecting PV Module Degradation
