Solar System Diagnostics & Troubleshooting in Las Vegas & Henderson
Bills creeping back up, monitoring gone silent, or partial production you cannot explain — Penny Electric runs full solar system diagnostics on existing Las Vegas arrays and tells you exactly what failed.
Solar System Diagnostics When Something Is Wrong
Solar system diagnostics is systematic troubleshooting of an existing array — production testing, inverter communication, optimizer or microinverter health, monitoring portal connectivity, and AC-side breakers — to answer why output dropped when nothing obvious looks broken.
Monitoring troubleshooting is a common subset: the app shows offline while the neighbor's panels are fine, or daily graphs flatlined after a grid outage. Sometimes the system produces but monitoring never updated — sometimes production truly stopped. We distinguish communication faults from real electrical faults so you pay for the right repair.
Annual inspections and performance checks fit here too — especially for homeowners whose original installer disappeared. A diagnostic visit establishes a baseline, catches degrading strings before they go to zero, and documents condition for insurance or a future home sale.
Part of our solar repair services; follow-on repair may be on our panel, inverter, or battery service pages once the fault is isolated.
This work is part of our complete solar repair services for Las Vegas and Henderson — licensed electricians who service existing residential solar and battery systems, not new array sales.
Signs You Need Solar Diagnostics
Higher bills despite having solar
Production may have dropped gradually — diagnostics finds the cause.
Monitoring offline or incomplete
App gaps may hide real production loss or be communication-only.
Partial string production
Some zones produce while others show zero — string-level fault.
Installer unavailable
No one to interpret monitoring data — we establish facts on site.

What Solar Diagnostics Includes
- Full system performance testing
- Monitoring & communication checks
- Inverter and optimizer analysis
- Written findings summary
- Repair recommendations with pricing
- Annual inspection options
Diagnostics leads to targeted repair — see solar inspection for code and sale-related assessments. Part of our solar repair services.
A diagnostic visit quotes separately from repair — you receive clear findings before authorizing component replacement. That separation matters when the fault is a $200 breaker versus a $5,000 inverter.

Solar Diagnostics FAQ
What does solar system diagnostics include?
Production testing, inverter and optimizer checks, monitoring communication, AC disconnect and breaker verification, and written findings.
Monitoring shows offline — is my system broken?
Not always — communication faults can show offline while limited production continues. We test on site to know for sure.
Why is my solar production down?
Causes range from inverter failure and panel damage to tripped breakers and optimizer faults — diagnostics identifies which applies.
Do you offer annual solar inspections?
Yes — scheduled diagnostics catch degrading performance before total failure, especially valuable when no installer maintains the system.
How much does solar diagnostics cost?
We quote based on system size and access — upfront pricing before testing begins.
