If PV systems are marketed as part of other direct marketing (not in the market premium model), guarantees of origin can be issued for the electricity generated. For this purpose, the plant operator must register the systems in the Register of Guaranties. If the guarantees of origin are to be remunerated through BayWa r.e., they must be transferred to BayWa r.e. in the Register of Guarantees. Remuneration shall then be made in accordance with the contractually agreed sum.
