Yield Forecasts: 4Cast Focuses on Growing Solar Market in Poland And Eastern Europe

Potsdam, Germany - The AI-based energy forecasting specialist 4Cast GmbH & Co. KG from Potsdam intends to offer its services throughout Europe.

The yield forecasts, which are based on state-of-the-art machine learning techniques and data analysis methods, will now be targeted at the growing solar market in Poland and Eastern Europe.

As precise yield forecasts promise a significant increase in efficiency, the high-growth market in Poland offers great potential for new customer business, according to the company. In January 2023, 4Cast made important business contacts at the Solar Energy Expo in Warsaw, acquiring both planners and operators of solar projects. From May 16-18, 2023, 4Cast will also present its yield forecasts at the Greenpower 2023 international exhibition in Poznan, Poland.

"More and more industrial companies are turning to self-supply with solar and wind energy. Knowing the expected electricity yields offers a great competitive advantage here," said 4Cast CEO Sascha Bauer.

4Cast's yield forecasts are based on a variety of different data. For example, weather data such as solar radiation, temperature, cloud cover and also wind speed are used, as well as site data such as orientation. Shading, which is important, is also integrated into the database.

Digitization increases the efficiency of yield forecasts. In the process, the use of machine learning enables faster and more accurate analysis of data, leading to better forecasts and decisions. "Our solar yield forecasts achieve very high precision. The monthly error rates (NMAE) are 3-5% in spring and summer and as low as 1-3% in autumn and winter," explains Annekatrin Kirsch, a meteorologist leading the development.
