A. If you are reporting to an agency for rebates, you need to check with them to see what derate they are requiring. Some states, such as Wisconsin have a set derate of .8. California derates the system for rebate purposes using only the inverter derate. Please check with your reporting agency. If you are using the software to size a system, we recommend that you use the calculate derate option for more accuracy.
