About the project
This Davie property is substantially larger than a typical suburban lot, and the home’s consumption profile reflects that: multiple HVAC zones, a pool and spa pump, landscape lighting, and two EV chargers. A standard 10 kW residential system would have covered maybe a third of the annual load. Sprightful designed a 44.5 kW array (106 Trina Solar 420-watt panels across the home’s multiple roof planes) to carry essentially the entire load on sunny days and export the surplus to FPL under net metering.
For storage and resilience, three Tesla Powerwall 3 units deliver 40.5 kWh of usable backup, enough to ride out a multi-day outage without shedding the pool, the EV chargers, or either AC zone. The Powerwall 3 platform was chosen over the Enphase stack specifically for the higher per-unit discharge rate, which matters for a home with this many simultaneously-running inductive loads.
