For solar PV, SOMAH uses an Expected Performance Based Buydown (EPBB) method to calculate incentives:

EPBB Incentive = Reserved Incentive Rate × System Rating (CEC-AC) × Design Factor

The CEC-AC system rating is based on the number of modules, their CEC ratings, and inverter efficiency. System sizing must also be consistent with on-site load and the required minimum tenant allocation.

To ensure your PV incentive amount matches what appears on required SOMAH forms:

• Confirm that the CEC-AC rating and system design details used in the EPBB calculation match the values entered in PowerClerk.
• Verify that the tenant and common-area allocation, the incentive rate selected (Table 4), and your ITC/LIHTC status are consistent across the Reservation Request, VNEM Allocation Form, and Incentive Claim Form.
• Update the application and supporting documents in PowerClerk if there are any changes to system design, allocation, or tax credit usage so the incentive is recalculated correctly.
