Hardware

What was installed, and why.

Modules — 62× panels
B-grade CS6.1-54TM-455-TOPHiKu6. Sized to cover the home's 12-month baseline load with a minor buffer for future electrification.
Inverter — Integrated (Tesla Powerwall 3 built-in solar inverter)
DC-coupled through the Powerwall 3's integrated 11.5 kW solar inverter. One device, one monitoring app, one fewer point of failure.
Battery — Tesla Powerwall 3 + Expansion Pack
81 kWh usable. Whole-home backup through grid outages, and time-of-use shifting when utility peak tariffs apply.
Racking — mounting system
Standoffs anchored with stainless-steel bolts directly into the roof trusses

Project notes

About the project

This Miami Beach residence sits in a coastal neighborhood where storm resilience and battery backup matter. That geography is exactly why the homeowner wanted serious storage alongside his solar: when hurricane-season outages stretch on, utility restoration can take time, and coastal homes need backup that can carry essential loads. Sprightful designed a 62-panel, 28.2 kW rooftop array paired with the largest battery bank of any home in our 22-project case study set — four Tesla Powerwall 3 units plus two Expansion Packs, stacking up to 81 kWh of usable storage.

For the roof itself we specified 62 B-grade Canadian Solar CS6.1-54TM-455-TOPHiKu6 modules. Rather than add string inverters or microinverters to the stack, we DC-coupled the PV directly to the Powerwall 3 units — each Powerwall 3 ships with an integrated 11.5 kW solar inverter, so four of them in parallel comfortably handle the full 28.2 kW array with zero extra hardware, a tighter monitoring footprint, and better battery-charging efficiency (DC-to-DC instead of DC-AC-DC). Signed October 6, 2025; permit approved and final inspection passed December 22, 2025.

FAQ

Solar in Miami Beach, FL.

How long does the solar permit process take in Miami Beach?

Miami Beach took 29 days from submittal to approval on this project. Typical range we've seen is 2–8 weeks depending on whether the roof assembly requires a secondary wind-load review.

What size solar system is typical for a Miami Beach home?

Most Miami Beach homeowners land between 8–16 kW — sized to offset 90–100% of their FPL bill. This project is 28.2 kW, on the larger end.

Does my HOA need to approve it?

Florida's Solar Rights Act (§163.04) prevents HOAs from outright banning rooftop solar. They can make reasonable aesthetic requests — we handle the HOA submittal directly and have a 100% approval rate to date.

What rebates and incentives are available in Miami-Dade County?

The 30% federal Investment Tax Credit (ITC) is the primary incentive — Florida has no state-level solar rebate. There's also no property tax increase for the added home value (Florida exemption), and no sales tax on the equipment.
