Project notes

About the project

When this West Palm Beach household set out to rein in their FPL bill, they didn't do it in a single leap — they did it the smart way, in two phases. Sprightful first designed a 21.45 kW rooftop array: 57 Canadian Solar 390-watt panels paired with 55 Enphase IQ 8+ microinverters, so every panel is its own independent generator and one shaded panel never drags the rest down. That system went live in November 2023, and the homeowners were exporting energy to FPL within a few weeks of the final install.

In 2025 they came back to us for phase two — two Enphase IQ Battery 10C units, adding roughly 20 kWh of whole-home backup to the existing Enphase stack. Because the original system was already Enphase, the batteries slotted in without replacing any of the 2023 hardware. That's the advantage of a modular platform: you build for today's budget, and you can add resilience later without starting over.

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).

“Great company — they did amazing work and were patient and thorough throughout the whole process. They made getting solar a breeze. Would definitely recommend them.”

FAQ

Solar in West Palm Beach, FL.

How long does the solar permit process take in West Palm Beach?

West Palm Beach took 227 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 West Palm Beach home?

Most West Palm Beach homeowners land between 8–16 kW — sized to offset 90–100% of their FPL bill. This project is 21.45 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 Palm Beach 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.
