Project notes
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.
