Solar incentive stack: timing and basis

Per-kWh incentive (USD per kWh) Year-1 output (kWh) Output loss per year (%) Per-kWh years (0 to 30)

Year	Rebate	Size-based	Cost-based	Per-kWh	Total (USD)	Present value (USD)

Every default is invented for illustration. The cost-based rate is a placeholder, not any country's credit. The calculator shows timing, caps and basis only. It is not tax advice. Per-kWh payments are expected, not guaranteed. Entries accept 12,500 or 0,15; a value such as 1.000 is ambiguous and is rejected, so write 1 or 1000.
