About the project

When this Miami homeowner put solar on the home in 2022, he didn’t just want panels. He wanted to stop worrying about grid outages during hurricane season. Sprightful designed a 30-panel 11.2 kW array pairing Jinko 370-watt modules with Enphase IQ 8+ microinverters, and stacked two Encharge 10 batteries alongside the existing FPL main panel for roughly 20 kWh of usable whole-home backup.

The Enphase IQ 8 platform lets the system 'sunlight backup', meaning even if the batteries are fully discharged during a multi-day outage, the panels will still power the home directly from the roof during daylight hours. For a property like this one, which relies on a well pump that can’t afford a long-duration outage, that capability was the whole reason for choosing the Enphase stack over a single-battery solution.

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).

“Pablo and his team were diligent, kept me informed, did masterful work, and overall it was a five-star experience. I’m so happy that I’m fully solar.”

Each AHJ has its own quirks: permit fees, setback rules, wind-load calcs. Here are similar projects we’ve run through the same county offices, close to Miami.

Solar in Miami, FL.

How long does the solar permit process take in Miami?

Unin. Miami-Dade took 117 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?

Florida does not currently offer a state-level solar rebate. Qualifying solar energy systems are exempt from Florida sales tax, and the value a renewable energy system adds to a residential property is excluded from its property-tax assessment.
