Project notes

About the project

This Boynton Beach system is interesting because it includes an Enphase Soft Starter — a purpose-built device that dampens the inrush current a central AC compressor draws at startup. Without one, running a 3- or 4-ton AC unit off a battery system either requires an oversized battery or accepts that the AC can't start during a backup event. With the Soft Starter, the full HVAC system runs off the batteries during an outage using roughly a third of the surge current it would normally pull.

The rest of the system is conventional: 25 Canadian Solar 390-watt panels, 25 Enphase IQ 8+ microinverters, and a three-battery Enphase stack totalling 30.24 kWh of usable storage. The batteries are sized to carry the home — with AC running — through a typical overnight outage, which is exactly the capability the Soft Starter is there to enable.

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).

“Let me say from the start that I am quite satisfied with my solar installation and Sprightful Solar after 3 months of being online. My goal was independence from the grid, so in addition to the panels I also have 3 batteries.
I need to preface this by saying I am a member of the Solar United Neighbors Co-op, which bids every year for a single vendor to provide solar installations to our members. I was also a member of the bid committee which selected the vendor. Sprightful Solar was the winning vendor in 2023. I contracted with Sprightful for a 9.75 kW panel system with 3 × 10 kVA batteries.
From the start Pablo (the owner) and Andrea were stellar. They processed paperwork and contracts quickly, reviewed all my needs, and generally got the ball rolling. Good so far.
Another disclaimer: I live in the City of Boynton Beach, and permitting and inspections can be a challenge. I know, because I am heavily involved in the projects for our rather large community. I knew their timelines were probably not realistic — but again, I live in the City of Boynton Beach. The long and short is that I would have no problem recommending Sprightful Solar to my friends, and I have. I will also temper their expectations — again because I live in the City of Boynton Beach.”

FAQ

Solar in Boynton Beach, FL.

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

Boynton Beach took 43 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 Boynton Beach home?

Most Boynton Beach homeowners land between 8–16 kW — sized to offset 90–100% of their FPL bill. This project is 9.75 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 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.
