How fast is the install once everything is approved?

On site, one to two days. The first day is the concrete pad, setting the generator, and running the electrical and gas connections plus the transfer switch. The second day, if needed, is commissioning, testing, and the homeowner walkthrough. The 30 to 90 day total timeline is mostly permitting and inspection scheduling with the city, not actual labor. The work moves fast once permits are in hand.
