Meet our team at Intersolar Europe 2024, June 19-21, at booth A4.140.

Discover solar energy forecasting at the upcoming Intersolar Europe

Our energy meteorology products and services are an indispensable part of many solar, hybrid and wind power systems. We enable you to track the cloud movement, calculate local irradiance levels and accurately forecast your solar farms’ performance. Nowadays, these functions have become essential for the solar industry, and are required by many grid codes all around the world. We provide weather data for all project phases from site assessments to trading on the energy market: Our team can supply you with everything from historical data and real-time monitoring to precise forecasts.

Our portfolio includes high-quality all-sky imagers for industrial and research applications that work reliably in different climatic conditions with minimal maintenance. Our sky cams – Sky InSight™ and Sky Cam Vision – are particularly in demand for the solar energy sector and atmospheric sciences. They deliver accurate short term cloud cover and solar power forecasts, which that are essential for grid management, optimising energy storage management and meeting grid operator requirements. Sky InSight™ utilises infrared technology to achieve highest precision, while Sky Cam Vision operates in the visible light range. Both systems are fully functional even in remote areas and have proven their quality in over 50 locations worldwide.

To complement local measurements, we offer our specialised satellite-to-irradiance service SunSat™. Satellite measurements allow for high quality reliable data worldwide, which are especially recommendable for larger areas, or complete portfolios of solar farms. With SunSat™, you can immediately recognise drops in performance or pollution of your system by comparing the actual with the expected performance based on satellite data – without on-site hardware installation. SunSat™ Digital Twin, provides solar asset managers with a reliable monitoring tool for a quick overview of their entire fleet.
