Fresno, Clovis & Central Valley
Solar Repair & Diagnostics
System not producing? Inverter error codes? Bird damage or a roof leak at a mounting foot? We diagnose and repair all major residential solar systems — including systems we did not install.
What we repair
From zero-production emergencies to slow performance degradation — we diagnose and fix the full range of residential solar problems.
System Not Producing
Zero or near-zero output during daylight hours. We diagnose inverter faults, tripped breakers, failed microinverters, and wiring issues.
Inverter Replacement
String inverter and microinverter replacement for all major brands — Enphase, SolarEdge, SMA, Fronius, Growatt, and others.
Ground Fault & Arc Fault
GFDI and AFCI fault diagnosis and repair. We locate the fault, clear the condition, and restore safe operation.
Performance Diagnostics
System producing less than expected? We test panel output, check shading, inspect connections, and review monitoring data.
Bird & Critter Damage
Squirrels and birds nest under panels and chew wiring. We repair damaged wiring and install critter guard to prevent recurrence.
Roof Leak Repair
Penetration leaks at mounting feet or conduit entry points. We locate the source, reseal, and restore weathertight integrity.
Remove & Reinstall
Temporary removal for reroofing, remodeling, or structural repairs. Full reinstall, inspection, and recommissioning included.
Monitoring Restoration
Enphase Enlighten, SolarEdge, or other monitoring offline? We reconnect gateways, update firmware, and restore visibility.
Brands we service
We work on all major residential solar equipment — including systems from installers who are no longer in business.

Common repair questions
Do you repair solar systems you did not install?
Yes. We service systems installed by any contractor — including companies that are no longer in business. We work on all major residential brands and inverter platforms. Bring us your monitoring app login or any error codes you have and we'll diagnose from there.
How much does solar repair cost in Fresno?
Diagnostic service calls start at a flat rate that covers the site visit and written assessment. Repair costs vary by issue: a single failed microinverter is $150–$300 installed; a string inverter replacement runs $1,500–$3,500 depending on size and brand; wiring repairs and critter damage vary by scope. We provide a written quote before any work begins.
My solar app shows zero production — what should I check first?
First, check your main electrical panel for tripped breakers — look for a breaker labeled 'Solar', 'PV', or 'Inverter'. If breakers are fine, check the inverter itself for error codes or a red/yellow LED. If the inverter display is blank, check whether the AC disconnect near the inverter is in the ON position. If none of those resolve it, call us — most zero-production issues are diagnosable over the phone in under five minutes.
How long does a solar repair take?
Most diagnostic visits take 1–2 hours. Simple repairs (tripped breaker, loose connection, single microinverter) are often completed same day. Inverter replacements typically take 2–4 hours once the replacement unit arrives. Critter guard installation is a half-day job for most residential systems.
Is it worth repairing an older solar system?
Depends on the system age and what failed. Panels last 25–30 years and rarely fail — if your panels are fine, repairing or replacing the inverter is almost always worth it. If the system is 15+ years old and multiple components are failing, we'll give you an honest assessment of whether repair or replacement makes more financial sense.
Do you repair solar systems with roof leaks?
Yes. Roof penetration leaks at mounting feet or conduit entry points are a known failure mode, especially on older installations. We locate the source, remove the affected hardware, reseal the penetration, and reinstall. We do not perform general roofing work — if the leak is in the roof membrane itself rather than at a solar penetration, we coordinate with a roofing contractor.
