Florida Power & Light (FPL) Solar Payback: Tier 1 vs Tier 2 Interconnection Rules
Florida Power & Light (FPL) still offers true 1-to-1 retail net metering plus a 100% Florida sales tax & property tax exemption on residential solar. However, commission-hungry sales reps routinely oversize systems past 11.76 kW DC (10 kW AC)—trapping homeowners in Tier 2 ($1,000,000 liability insurance).
1. FPL Tier 1 vs. Tier 2 Interconnection Thresholds
| FPL Rule / Requirement | Tier 1 (≤ 10 kW AC / ~11.76 kW DC) | Tier 2 (> 10 kW AC up to 100 kW) |
|---|---|---|
| FPL Application Fee | $0 (Free Fast-Track) | $400 Non-Refundable Fee |
| Mandatory Liability Insurance | None Required | $1,000,000 Personal Umbrella Policy (~$500/yr) |
| 25-Year Cumulative Insurance Cost | $0 | +$12,500 to $16,000 in umbrella premiums |
| Monthly Export Credit | 1:1 Full Retail kWh Rollover ($25 min bill) | 1:1 Full Retail kWh Rollover ($25 min bill) |

Frequently Asked Questions
What is the difference between FPL Tier 1 and Tier 2 solar interconnection in Florida?
Florida Administrative Code Rule 25-6.065 divides residential solar into Tier 1 (10 kW AC or less, roughly 11.5–11.7 kW DC of panels) and Tier 2 (>10 kW AC up to 100 kW). Crossing into Tier 2 requires you to carry a $1,000,000 personal liability umbrella insurance policy ($350–$650/year forever), pay a $400 FPL application fee, and install an external manual disconnect switch.
Does Florida Power & Light (FPL) still offer 1-to-1 net metering in 2026?
Yes. Following the veto of HB 741, FPL continues to credit excess kWh exported to the grid at a 1-to-1 full retail rollover rate month-to-month, subject to FPL's $25/month minimum base bill requirement and an annual January true-up at wholesale COG-1 rates (~2.8–3.5¢/kWh).
How can I install more than 11.7 kW of solar in FPL territory without triggering Tier 2 insurance?
By using a hybrid inverter (like the EG4 18kPV) configured or derated to a 10.0 kW AC maximum continuous grid export limit—or by pairing additional off-grid/zero-export panels directly into a 48V LiFePO4 battery bank—you can harvest 14–18 kW of DC solar while remaining under FPL's 10 kW AC Tier 1 interconnection cap.
