Solar power generation is highly variable; a single cloud can drop production by 80% in a matter of minutes. To efficiently integrate solar energy into electricity grids and markets, accurate advance knowledge of production is crucial.
That’s why Steadysun developed a reliable solar power forecasting solution. By integrating atmospheric dynamics (including cloud cover, live irradiance data, and weather data for solar panels), our ultra-accurate solar energy forecasts empower you to:
Maximize the financial return of your solar installations, reduce balancing penalties and secure your revenue even during periods of high weather variability.
Strategically plan your maintenance interventions based on optimal weather windows and increase the operational efficiency of your plants.
Manage your photovoltaic portfolio with confidence using reliable short and medium-term forecasts. Turn solar variability into a competitive advantage.
Effectively integrate intermittent solar energy into your energy mix and reduce network balancing and congestion costs.

Q&A
Solar power forecasting is the process of estimating the amount of electricity that photovoltaic (PV) systems will generate over a given period. ☀️ By combining weather data, cloud movement, irradiance, and AI models, our ultra-accurate energy forecasts help operators anticipate production fluctuations and optimize grid management.
More accurate is the forecast, more confident and profitable your energy decisions become. 🎯 Accurate solar forecasting allows energy managers to maximize power production, reduce grid instability, lower operational costs, and better integrate renewable energy into electricity markets. It also helps anticipate extreme weather events, minimizing risks to infrastructure.
