What is Solargis Forecast API?

With Solargis Forecast API you can get a reliable prediction of how much solar power your PV plant will generate in the coming minutes, hours, and days, for a period of up to two weeks.

Every 5/10/15 minutes, Solargis Forecast API provides short-term forecast data – or nowcasting – for up to 3 hours ahead.

  • XML format via REST API
  • Solar power output forecasts for up to 14 days
  • Nowcasting updates up to every 5 minutes
  • Minimize penalties from grid operators
  • Schedule maintenance based on the forecasts
Minimize penalties from grid operators

Minimize penalties from grid operators

Due to the high variability of renewable power output, accurate forecasting has become critical for maintaining grid stability.

With Solargis Forecast API, you can report with much higher confidence how much power your solar power plant will provide to the grid. This helps you minimize potential under- and over-delivery penalties from grid operators.

Maximize earnings in markets with fluctuating energy prices.

Accurate forecasts of solar energy production help you optimize the performance of hybrid PV-plus-battery systems, thanks to better management of battery charging and energy dispatch.

Find the right time for site maintenance

Find the right time for site maintenance

Solargis Forecast API is based on global Numerical Weather Prediction (NWP) and satellite-to-irradiance models, making it one of the most precise forecast services available on the market.

Precise forecasting allows you to plan site maintenance to minimize potential losses – for example during a period of cloudy weather when expected PV performance is reduced.
