Solar Panel Repair & Maintenance in Auburn & the Foothills
When a solar system stops pulling its weight, you don’t need a new sales pitch — you need someone who can actually fix it. King Electric & Solar is a licensed, insured local electrical contractor, not a fly-by-night solar-sales outfit, and we repair and maintain existing solar systems of any brand throughout Auburn, Placer County, El Dorado County and the Nevada County foothills. Panels that aren’t producing, an inverter throwing faults, or an original installer who has vanished — we diagnose it, fix it, and get your system earning its keep again. If you’re planning a brand-new array instead, see our solar panel installation service.
System Stopped Producing? We Diagnose Any Brand
A solar array that suddenly makes less power — or none at all — almost always has a specific, fixable cause. We track it down and repair it, no matter who installed the system:
- Inverter troubleshooting & replacement — the inverter is the most common point of failure. We diagnose error codes, no-output and overheating faults, and replace failed string inverters with a compatible unit.
- Micro-inverter & optimizer issues — a single failed micro-inverter or power optimizer can drag down a whole panel or string; we isolate the dead unit and swap it.
- Panel & string faults — cracked or degraded panels, hot spots, blown diodes and open strings that quietly cut your production.
- Monitoring & communication faults — when the app or gateway shows offline or zero, we restore the monitoring, gateway and Wi-Fi/cellular link so you can trust the numbers again.
Wiring Repair, Panel Removal & Ongoing Maintenance
Beyond the big components, most of what keeps a system healthy is careful electrical work and regular attention — exactly what a licensed electrical contractor is built for:
- Ground faults & wiring repair — we find and correct ground faults, arc faults, chewed or sun-damaged wiring, corroded connectors and failed conduit that trip the system offline. See our electrical troubleshooting service.
- Panel removal & reinstall for roof work — getting a roof repaired or replaced? We safely detach and store your panels, then reinstall and rewire them once the roofing is done.
- Maintenance, inspection & performance checks — a scheduled once-over of connections, mounting, torque, wiring and output, so small problems get caught before they cost you a season of production.
- Adding battery backup to an existing array — keep the panels you have and add storage so you’re covered when the grid goes down. Learn more about solar & battery storage.
Panels Not Producing, or Your Installer Vanished?
It’s one of the most common calls we get: the solar company that sold and installed the system is out of business, unreachable, or simply won’t come back — and now the panels aren’t producing and nobody will stand behind them. You don’t have to live with a dead array. As a licensed local electrical contractor, we can take over service on an orphaned system of any brand or installer: diagnose why it stopped producing, repair or replace the failed inverter, optimizers, wiring or panels, and restore the monitoring so you can see it working again. Local, licensed, insured, and here for the long haul — not a pop-up solar-sales operation.
Frequently Asked Questions
- Will you service a solar system your company didn’t install? Yes — that’s most of what we do. We repair and maintain existing solar arrays of any brand, regardless of who originally installed them, including systems whose installer is no longer in business.
- My panels stopped producing — what’s wrong? Most often it’s a failed inverter, a dead micro-inverter or optimizer, a tripped ground or arc fault, or a wiring or connector problem. We diagnose the exact cause instead of guessing, then repair it.
- Can you replace just the inverter? Yes — if the panels are fine but the inverter has failed, we replace it with a compatible unit and get the system back online, without replacing the whole array.
- My monitoring app shows the system offline — is that a real problem? Sometimes it’s just a lost gateway or Wi-Fi connection, and sometimes it means the system really is down. We check both, restore the communication link, and confirm the array is actually producing.
- I need my roof repaired — can you remove and reinstall the panels? Yes. We safely detach and store your panels and mounts, coordinate with your roofer, then reinstall and rewire the system once the roofing work is finished.
- Can you add battery backup to the solar I already have? In many cases, yes — we can add battery storage to an existing array so you keep power during outages. See our solar & battery page.
- Are you licensed and insured? Yes — King Electric & Solar is a licensed, insured California electrical contractor serving Auburn and the Placer, El Dorado and Nevada County foothills.
