Year One Cost After Incentives

How do I determine the Year 1 cost of a PV project after the tax credits and other incentives are applied from a homeowner's perspective? I expect to find the value in the cash flow, but do not see it there.
For the Residential and Commercial financial models, the "After-tax annual costs" row (at the bottom of the Cash Flow table) shows the cost in each year. The cost in Year zero is the initial investment, and the costs in subsequent years are maintenance, debt servicing, and tax-related costs. A positive value indicates net income (from tax benefits), and a negative value indicates a net expense. 
Best regards,

Paul.
