Assumptions
CAD
Enter only an independently verified capital adjustment. It is separate from the ITC assistance question.Formula contract
- Modeled capacity is the lower of the entered target, roof, and load-matched capacity bounds that are available. Roof capacity = usable roof area ÷ 6 m²/kWdc.
- Annual generation method: annual generation uses 80% to 90% of the reviewed municipal annual resource value.
- Annual energy value method: Explicit export scenario: import portion = annual generation × (1 − export share) × entered import value; export portion = annual generation × export share × entered export credit; total annual energy value = import portion + export portion. Without complete export inputs or an explicit all-self-consumed confirmation, annual energy value remains suppressed. Annual matching does not establish interval self-consumption, coincidence, tariff ratchets, or future rates.
- Simple payback method: low cost divided by high annual benefit gives the low boundary, and high cost divided by low annual benefit gives the high boundary. Entered O&M is deducted from annual benefit.
- Clean Technology ITC method: entered eligible basis less entered assistance, multiplied by the applicable official rate.
- Capital cost allowance method: the screened deduction follows the selected ITC and UCC treatment and entered tax rate.
- Storage bound method: peak clipping is limited by power, discharged energy over the event, entered target, and observed peak. Per-cycle value subtracts full charged-energy cost from discharged-energy value.
- Cash-flow method: the 25-year chart discounts the midpoint of each visible user-defined range. Payback preserves a reached boundary and a not-reached boundary when only part of the range crosses within the horizon.
Source record
Choose a municipality to expose its exact reviewed source record.
The reviewed NRCan municipality records use 1974 to 1993 climatology coverage and publish annual resource in kWh/kWp/year. The metadata record was modified 2024-02-15, which does not extend the measurement period.
