Solar panel repair and O&M

Solar Panel Repair & Troubleshooting in Los Angeles

We troubleshoot and service existing and orphaned solar systems even when the original installer is unavailable. Low or zero production can come from the inverter, AC supply, breakers, disconnects, modules, optimizers, microinverters, wiring, connectors, monitoring, roof conditions or utility voltage. We test the AC and DC sides before recommending a repair.

Questions customers ask

Direct answers before you call.

Who repairs solar panels when the original installer is gone?

A qualified solar and electrical service contractor can evaluate an orphaned system. Eco Solar & Electric services existing systems and documents inverter, array, wiring, monitoring and utility-side findings.

Why is my solar system producing less power?

Production loss can involve shading or soiling, module or optimizer faults, damaged connectors or conductors, isolation faults, inverter problems, monitoring errors or utility-voltage conditions.

Does a solar alert always mean the inverter failed?

No. The inverter may be reporting a fault elsewhere in the array or electrical supply. Testing the AC and DC paths helps avoid replacing an inverter that is not the root cause.

Laguna Niguel, California • Real job video

Enphase Microinverter Replacement and Commissioning

Solar Wholesale Group dispatched Eco Solar & Electric to a Laguna Niguel home for an approved Enphase microinverter replacement. This field video documents safe tile-roof access, the affected module and under-module equipment, replacement work, the Enphase combiner and the serial-number handoff used to retire the old device and commission the replacement in the existing monitored system.

Signal Hill, California • Real job video

SunPower ‘Missing Grid’ Solar Diagnosis for a Managed Property

PMI Patron called Eco Solar & Electric for a solar system at a managed multifamily property in Signal Hill. The SunPower inverter reported that the grid was missing. Field testing traced the condition to the 20-amp solar backfeed breaker, which was off and not fully seated in the panel. We reseated the breaker, restored the AC connection and verified the system operating again before documenting the result for the property manager.

Palos Verdes Estates, California • Real job video

Aurora Solar Inverter Error Diagnosis

This Palos Verdes Estates homeowner found Eco Solar & Electric through Google, reviewed our customer feedback and website, then called us directly. Her service call involved two legacy Aurora inverters: one operating and one reporting E031. The manufacturer identifies E031 as an internal error involving voltage measured at the output relay. We compared the paired equipment, verified the AC supply, checked the DC array inputs and followed a controlled restart before documenting the repair and replacement path.

Tesla Powerwall 3 Mid-Circuit Interrupter Troubleshooting

We evaluated a Powerwall 3 solar shutdown problem by testing the photovoltaic strings and mid-circuit interrupter paths. This methodical process helps distinguish an MCI issue from conductor, connector or other solar-array faults.

Rolling Hills Estates, California • Instagram

Two SMA Sunny Boy Inverters Stopped Producing

Problem: both SMA Sunny Boy inverters on this ground-mounted solar system were no longer producing power. Solution: we diagnosed the inverter and array conditions, documented the failure and provided a favorable replacement path to restore reliable solar production and modern monitoring.

Field experience

Real Los Angeles and Orange County solar repair and inverter diagnostics.

Our documented work now includes a Laguna Niguel Enphase microinverter replacement with serial-number mapping and commissioning; a Signal Hill SunPower missing-grid service call; a Palos Verdes Estates Aurora E031 diagnosis; Tesla MCI troubleshooting in Granada Hills; and a Rolling Hills Estates ground-mount system with two nonproducing SMA Sunny Boy inverters. These cases show why solar repair starts with evidence—not guessed parts.
