Solar Not Producing?
If your monitoring app or electric bill suggests your solar system isn't producing, this guide explains what might be happening, what you can safely check, and when to get help.
Understanding the Problem
A drop in reported production can mean two very different things: your system has actually stopped producing electricity, or your monitoring system has stopped reporting data while the system continues to run. These are separate problems with different solutions.
Before assuming equipment failure, check daytime status using the instructions for your specific equipment. Some string inverters have a display; many newer models and microinverter systems do not. A dark, sleeping, or unavailable display alone does not establish failure, especially at night or in very low light. A current power reading indicates generation at that moment, not total production during a reporting gap.
Possible Causes
These are possibilities to consider — not a diagnosis of your specific system.
Inverter fault or shutdown
The inverter has detected a condition (ground fault, overtemperature, grid issue) and shut down or entered an error state.
AC breaker tripped
The breaker between the inverter and your electrical panel has tripped, cutting power from the solar system.
Grid outage or voltage trip
The utility grid is down or experiencing voltage outside the inverter's operating range, causing it to disconnect for safety.
Monitoring communication loss
The system is producing but the monitoring gateway has lost its internet connection, so the app shows no data.
Shading or soiling
New shading (tree growth, construction) or heavy soiling (dust, pollen) has reduced output significantly.
Equipment failure
A component — inverter, optimizer, or string — has failed and stopped producing.
Safe Info to Collect
- • In daylight, record current app status or safely visible model-specific indicators, if available; many systems have no inverter display.
- • Indicator lights: What color are they — green, red, yellow? Solid or blinking?
- • If safely visible without opening an enclosure, note the solar breaker position. Do not operate or reset it unless the equipment-specific instructions say to.
- • When did you first notice the drop in production?
- • Weather conditions at the time (storm, lightning, heavy snow)?
- • Any recent work on your home's electrical system?
- • Screenshots of the monitoring app showing the production drop
Do not open electrical equipment or access rooftops. A qualified technician should handle physical inspections.
What Remote Support Can Establish
- Review your monitoring data to distinguish a communication issue from an actual production loss
- Interpret fault codes for your specific inverter make and model
- Help you identify which safe checks to perform
- Determine whether the issue likely requires onsite work
- Provide written findings and recommended next steps
When a Qualified Onsite Technician Is Needed
- Electrical testing of the inverter, strings, or breakers
- Physical inspection of panels, wiring, or connections
- Equipment replacement or repair
- Rooftop or panel-level access
We do not perform electrical repairs, rooftop inspections, or equipment replacement. When onsite work is needed, we coordinate referrals to qualified local contractors with your permission.
What Our Service Delivers
- A remote review of your monitoring data and fault information
- An assessment of whether the issue is communication-related or a true production loss
- Interpretation of fault codes for your specific equipment
- Written findings explaining what is likely happening
- Recommended next steps, including when to contact a manufacturer or onsite technician
Pricing and Approval
Submitting a request is free. Technical support is quoted separately, and paid work begins only after you approve the scope and price. Each situation is different — we review your details and provide a quote based on the specific work involved.
Equipment-specific evidence and next steps
Compare the last reporting timestamp with a daytime production interval. On Enphase systems, distinguish a gateway-to-cloud outage from individual microinverters not reporting to the gateway; neither alert alone proves zero generation. On SolarEdge systems, use the instructions for your exact model: LCD-equipped and LED-only models have different indicators. Do not open equipment or repeatedly reset breakers.
Independent review or manufacturer first?
Start with manufacturer support for an active safety fault, a documented model-specific error, or a possible warranty replacement. Independent review is useful when production, communications, and utility records disagree, or you need an organized evidence package across vendors.

Sample homeowner findings report — illustrative example
Fictional educational example, not a customer case, verified diagnosis, or evidence of past results. It illustrates the written findings format; your agreed scope determines the actual deliverables.
- Question and agreed scope
- Is the monitoring gap evidence of lost production? Remote review of owner-provided screenshots and accessible status indicators; no onsite measurements.
- Evidence reviewed
- Illustrative gateway alert: last cloud update at 10:15 on the day the owner changed Wi-Fi credentials. A subsequent daytime status screenshot reports generation. Model-specific manufacturer reconnection instructions consulted. No credentials or financing records requested.
- Findings and confidence
- The sequence is consistent with a gateway-to-cloud connection loss. The later status is evidence of generation at that moment only. It does not establish total energy yield during the reporting gap or exclude separate equipment faults.
- Recommended actions and responsibility
- Owner: follow the manufacturer’s app-based network reconnection instructions for the installed gateway. Monitoring provider: address account/cloud access if reconnection fails. Qualified onsite technician: inspect hardwired gateway power or persistent device faults when manufacturer support recommends it.
- Verification and escalation
- After reconnection, confirm current timestamps and a complete daytime reporting interval. Escalate persistent fault alerts to the manufacturer with the model and event history. Do not treat estimated backfill as measured production.
- Limitations and handoff
- No enclosure opened, wiring tested, rooftop accessed, warranty remedy authorized, or savings guaranteed. A real report would identify its named preparer, issue date, evidence received, unresolved questions, and the agreed follow-up.
