Solar repair & O&M — for any system.
If your panels aren't producing what they should — or your installer disappeared — Nexis services solar systems of any brand. We diagnose production drops, inverter faults, monitoring outages, and roof-penetration issues, make the repair, and get your system (and your credits) back to full output.
Why homeowners call Nexis for service
Get your production — and your savings — back
Solar is low-maintenance, not no-maintenance. Inverters fail, monitoring drops offline, connectors corrode, animals nest under arrays, and orphaned systems lose whoever was supposed to support them. Any of these can quietly cut your production and your net-metering credits for months before you notice.
Nexis is a full O&M provider: we service any brand of panel and inverter, whether or not we installed it. We find the actual fault, fix it right, and restore your system to spec — then can keep monitoring it so it doesn't happen again.
What our service covers
- Production diagnostics — panel-level analysis to find exactly what's underperforming and why.
- Inverter & microinverter repair — troubleshooting and replacement for Enphase, SolarEdge, SMA, and more.
- Monitoring restoration — get your app and utility reporting back online so your data is trustworthy again.
- Roof-penetration & flashing repair — stop and prevent leaks around mounts, done by a licensed roofer-electrician team.
- System takeovers — orphaned by your original installer? We'll adopt, document, and support your system.
- Preventive maintenance plans — periodic inspection, cleaning where useful, and monitoring so issues get caught early.

Service FAQ
Answers, straight up
Yes — that's a large part of our O&M work. We service any brand of panel and inverter regardless of who installed it, and we welcome system takeovers from homeowners whose original installer is gone.
The most common causes are an inverter or microinverter fault, a tripped or failed component, shading changes, soiling, or a monitoring dropout masking the real number. We run panel-level diagnostics to pinpoint it rather than guess.
Yes. Because we're a licensed HIC and roofer as well as an electrician, we can repair flashing and roof penetrations correctly and re-seal the array — something a solar-only company often can't.
Yes. We offer preventive maintenance and monitoring so problems are caught early, before they cost you months of lost production and credits.
