Sander Posted November 22, 2021 Report Share Posted November 22, 2021 Hello, Is there a way to calculate the payback time of a project when installing a retrofit battery? (So there is already a PV-system in place, but the customer wants to add a battery.) The payback should be based upon the increased lvl self-consumption and the cost of the battery expansion.
