Accurately predicting the return on investment for solar panel systems is a challenge faced by many financial institutions and banks providing the required capital for such deployments. Raiffeisen Bank Czech Republic has collaborated together with the European Union Agency for the Space Programme (EUSPA), ARMINES, and Evenflow, to demonstrate how Copernicus CAMS and C3S data can support accurate yield and return on investment forecasting for various types of solar panel technologies for any installation location in Czechia.
