Hardware

What was installed, and why.

  • Modules — 36× panels

    Silfab 310W. Sized to cover the home's 12-month baseline load with a minor buffer for future electrification.

  • Inverter — SE11400US

    Grid-tied inverter equipment converts rooftop production for home loads and FPL net metering.

  • Racking — mounting system

    Standoffs anchored with stainless-steel bolts directly into the roof trusses

Project notes

About the project

When this family first came to Sprightful in early 2018, rooftop solar in Miami-Dade was still a novelty — most neighbors still thought of it as an experiment rather than a utility. The homeowners were not buying an experiment. They wanted a system that would sit quietly on the roof, produce for twenty-five years, and let them forget about it.

Sprightful designed a 36-panel, 11.2 kW array using Silfab 310-watt modules paired with SolarEdge P300 optimizers and a single SE11400US string inverter — a topology chosen for long-term serviceability since every component can be swapped without touching the others. The system has been quietly producing since 2018, and the property has since changed hands, with the new owners inheriting the same no-drama solar production the original owners built.

Why it matters

A 30-year financial and environmental decision.

These aren't projections pulled from thin air. FRCC eGRID emissions data, current FPL residential tariff, and modeled production under South Florida irradiance (~1,500 kWh/kW/yr).

Good-faith estimates using FRCC eGRID emissions data, current FPL tariff, and Aurora-modeled production. Actual results vary with shading, weather, and future rate changes.

FAQ

Solar in Miami, FL.

How long does the solar permit process take in Miami?

Doral took 62 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 home?

Most Miami homeowners land between 8–16 kW — sized to offset 90–100% of their FPL bill. This project is 11.2 kW, on the standard 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.
