FAQ
Is this a contractor quote?
No. This is a planning model. Final pricing depends on local code, site constraints, fuel availability, and installer scope.
What usually causes the biggest budget surprises?
Transfer switch/panel upgrades, trenching distance, gas line work, and permit-driven scope changes are the most common hidden drivers.
How should I use the payback output?
Treat payback as a decision aid. Compare at least two outage assumptions (normal year vs severe year) and combine with resilience goals.
