Repair & maintenance
Solar panel repair and maintenance across Southern California
System gone dark and the installer won't call back? We diagnose and fix residential solar across SoCal — including systems we didn't install.
Your solar system stopped producing — or the app's been dark for weeks — and the company that installed it has gone quiet, merged, or vanished. That's the most common call we get in Southern California, where a decade of aggressive door-to-door installers left thousands of homeowners holding orphaned systems. Helios repairs and maintains residential solar across LA, Ventura, Orange, and the Inland Empire, including systems we didn't install. Between SCE's rate hikes and the NEM credits you've already paid for, every week of underproduction is money off your roof. We diagnose what's actually wrong and quote the fix in plain numbers before we touch anything.

How a service call works.
- 1
Phone triage (free)
We ask what the system is doing — or not doing — and check whether it's a reset you can do yourself. Half of "dead" systems are a tripped breaker or a comms dropout we can talk you through at no charge.
- 2
On-site diagnostic
A technician inspects the array, inverter, conduit, rapid-shutdown, and monitoring, and tests production to find the real fault. The diagnostic is a flat fee, quoted upfront and credited toward the repair if you proceed.
- 3
Transparent quote
You get the fix in line items — part, labor, permit if required — before any work. If it's cheaper to replace than repair, we say so. If it's under warranty, we help you file rather than charging you.
- 4
The repair
Most single-fault repairs are done in one visit. Roof-related work and panel removal/reinstall jobs are scheduled around your roofer.
- 5
Verification
We confirm the system is back to expected production and the monitoring is reporting before we leave.
Repair & maintenance by city
Solar repair questions, answered.
- How much does solar panel repair cost in Southern California?
- It depends on the fault. A comms or monitoring fix can be minor; an inverter replacement is the most common larger repair and varies by brand and size. We charge a flat diagnostic fee to find the real problem, then quote the repair in line items before any work — credited back if you proceed. We never quote a repair price sight-unseen.
- Do you repair solar panels you didn't install?
- Yes. Most of our service calls are for systems installed by other companies, including installers who have since closed. We diagnose the array, inverter, and wiring regardless of who built it, and document everything so your manufacturer warranties stay valid.
- How do I know if my solar panels need repair?
- Common signs: your electric bill jumped without a usage change, your monitoring app shows zero or partial production, an inverter light is red or off, or the system stopped after an outage or storm. If your app has been dark for more than a few days, the system likely isn't producing.
- Can you remove and reinstall my panels for a roof replacement?
- Yes — one of our most-requested services. We safely detach and store your array, coordinate with your roofer's timeline, then reinstall and recommission the system once the new roof is on. We re-flash every penetration and verify production afterward.
- Which solar platforms do you service?
- We work on the common residential platforms on SoCal roofs, including Tesla, Enphase, and SolarEdge systems. Enphase microinverter and SolarEdge optimizer faults are often isolated to a single unit, which keeps repairs targeted and affordable.
