Solar Payback Ledger
Payback requires an explicit owner cash-flow ledger. GeoStellar no longer produces a default break-even or lifetime-return result from national assumptions.
Cash-owner payback ledger
Enter an explicit amount—including 0.00 when the amount is truly zero—for every applicable category and year. Year 0 uses only other owner costs and incentives received; later years use only incentives, avoided and exported utility value, remaining utility charges, operations and maintenance, and replacement costs. Use “Add another” when the same category has more than one record in a year; those records are summed exactly in cents. Every nonzero incentive keeps its own amount, jurisdiction, receipt year, and four-digit, non-future source-event year. Loan proceeds/payments, lease payments, and PPA energy charges never enter this owner-asset payback table.
Enter a whole-year horizon from 1 through 100 to create the cash-flow table.
Enter the required owner cash-flow values. Missing: Unfinanced cash price, Payback horizon.
Method boundary
The payback guide explains simple and discounted crossover. The linked owner ledger exposes every modeled year, keeps debt and third-party contracts outside asset payback, and reports no crossover when the entered cash flows do not recover the owner outlay.
