Your backup priorities, your electrical service and panel, where the battery will go, and the controls it needs. The scope covers permits, utility paperwork, setup and a walkthrough when it is done.
On APS or SRP? We check their requirements for your setup. Some equipment, like a meter-mounted backup switch, depends on what the utility accepts and what fits your home, so we pick the arrangement after we have seen it.
Older or smaller panels sometimes need a panel or service upgrade first. Planning an EV charger too? Tell us, because it changes the panel math.
