PV Installation during EAp2 and EAc1 performance period

My group is currently planning to have photovoltaic panels and the appropriate electricity meters installed on the LEED EBOM project building. A number of the performance periods have already begun, while others have yet to begin. It is my understanding that only the EAp2 and EAc1 (both of which the project is pursuing) require a 1 year performance period, and that EAc4 only requires a 3 month performance period. Is this correct? A part of the EAp2 credit form is a bit confusing. It reads, "Enter the start and end dates for the EA Credit 4 performance period. If EA Credit 4 is not being pursued, enter the start and end dates for a period of at least three (3) months and no longer than two (2) years over which on-site renewable energy data." However, it does not go on to say what to do if EAc4 is being pursued. Is our three month performance period for EAc4 (measured and recorded energy usage with PV panels) and our one year performance period for EAp2 and EAc1 OK? (with three months of alternative energy affecting its' outcome). Or, do we have to monitor the electricity usage with the PV panels for a year to receive credit for EAp2, EAc1 and EAc4?
