Of course, banks are not risking, that the future electricity price will be low during peak solar production and they don't get their money back:

"Dama Solar was also awarded two Contracts for Difference (CfDs) by the Romanian government last year. The grants are part of a low-carbon energy-support scheme paid for with EU funds, based on CfD, which set the power price at an agreed level for 15 years."
