Incentive status
Incentives can materially change net cost, but SolarCalcNow does not include them in default calculations unless they are source-checked, dated, active, eligibility-scoped, and explicitly included in the data model.

Before signing, obtain the program's written eligibility decision, eligible cost basis, payment schedule and ownership terms. A tax reduction, a production-credit sale and an upfront rebate affect cash flow differently. No program amount below is automatically included in payback.
The calculator shows gross cost first. A verified incentive can be shown as a separate note or included in net cost only after its source, active status, eligibility rules, and date are reviewed. This keeps outdated tax credit assumptions from quietly changing payback math.
