How this result was calculated
Self-consumed kWh = annual production × self-consumed share. Annual savings = self-consumed kWh × tariff + exported kWh × export credit − maintenance. Net cost = installed cost − incentive. Payback = net cost / positive annual savings; otherwise there is no payback.
Country setup: United States. Displayed measurements are converted to the formula's base units internally.
Assumption: A single typical year and simple payback. No degradation, tariff escalation, financing or discounted cash-flow model is included. United States planning scenario.
