We service and repair existing residential solar systems. We do not install new solar panels. If your system was installed by someone else and isn’t performing — or the original installer is gone — we can help.
A solar system that isn’t producing is losing you money every sunny day. Florida Electrical & Fire Alarm LLC troubleshoots and repairs residential solar electric systems across Port St. Lucie, Fort Pierce, Stuart, Jensen Beach, and Palm City — panels, inverters, disconnects, and AC-side wiring. Florida Electrical License #ER13016161.
Signs Your Solar System Needs Repair
- Your monitoring app shows zero or declining production on sunny days.
- The inverter shows an error code, a red light, or no lights at all.
- Your electric bill jumped back up.
- Visible damage — cracked panels, corroded wiring, or storm damage.
- The system shuts off repeatedly.
- The inverter is over 10 years old with fading performance.
Solar Inverter Troubleshooting & Repair
The inverter is the most common failure point in a residential solar system. We diagnose both string and microinverter systems — error-code diagnosis, DC/AC voltage testing, ground-fault tracing, and replacement of failed inverters and optimizers.
What We Repair
- Solar inverters — diagnosis, troubleshooting, and replacement.
- Damaged or underperforming panels — testing and replacement.
- DC/AC disconnects, combiners, and rapid-shutdown equipment.
- Corroded or storm-damaged wiring.
- Monitoring system issues.
- AC-side electrical — breakers, subpanels, and interconnections. If the issue involves your electrical panel, we handle that too.
Our Diagnostic Process
- Production review — we look at your monitoring data to understand what’s happening.
- On-site testing — panel voltage checks, inverter diagnostics, and wiring inspection.
- Straight answers — what failed, what it costs, and whether repair makes sense.
- Repair and verification — we fix it and confirm your production is restored.
Frequently Asked Questions
My inverter shows an error code — what does it mean?
It varies by brand — Enphase, SolarEdge, SMA, Fronius, and others all use different codes. Note the exact code displayed and call (561) 552-3753 — we can diagnose it from there.
One panel looks darker — is that a problem?
It can indicate a failed cell or bypass diode. We test individual panels to find out what’s happening and whether replacement makes sense.
My solar installer went out of business. Can you service my system?
Yes — that’s one of our most common calls. We service systems installed by other companies, including orphaned systems.
Do you install new solar panels?
No — we specialize in the repair and troubleshooting of existing residential solar systems. We do not install new solar panels.
Solar system underperforming? Call Florida Electrical & Fire Alarm at (561) 552-3753 — we’ll diagnose it and get your production back.
