Did Your Solar Installer Go Out of Business? How to Rescue & Repower an Orphaned Array
Every week, NYREER’s Clifton Park engineering desk receives calls from commercial building owners, municipalities, and homeowners across NY, NJ, VT, and MA with the same story:
"Our solar panels are still on the roof, the sun is shining, our electric bill just doubled, the inverter screen shows an isolation fault, and the company that installed our system five years ago disconnected their phone number."
When a solar installer goes bankrupt, most other solar sales companies refuse to help—they only want to sell brand-new systems. NYREER’s Orphaned System Rescue Division was built specifically to restore, repower, and maintain these stranded assets.
The 3 Most Common Failure Modes in Orphaned Northeast Systems
- DC Ground / Isolation Faults After Snowmelt or Rain: Often caused by pinched array home-run wires, unsealed rooftop junction boxes, or squirrel damage under the modules. We locate the exact faulted string in minutes using 1,000V insulation-resistance testing and IV-curve tracing.
- Failed Inverter Capacitors, Relays, or Obsolete 3G Cellular Cards: Many 7-to-12-year-old inverters are actually still generating power—or only need a contactor board—but lost monitoring when 3G cellular networks shut down.
- Sub-Tier Inverters Whose Manufacturers Left the U.S. Market: When an off-brand inverter fails completely, NYREER engineers a drop-in Inverter Repowering using SMA (German) or USA string/hybrid inverters—matching the existing roof string voltages so not a single roof panel has to be removed.
