Path-Q Solar
What should I do if solar production remains low after clouds have cleared?
Answer
First verify that the monitoring period, weather, shading, snow, dust, and grid status are normal; then check for alerts, offline devices, and inverter or battery operating states without opening or servicing equipment. If low production persists or is localized, contact the installer or service provider and document the issue for warranty or performance review.
Key points
- Compare current output with similar clear-day history and expected output for the system's orientation.
- Check monitoring communications, inverter status, fault codes, disconnects, and utility outage information.
- Look for new shading, snow, dust, physical damage, or construction near the array.
- Separate whole-system underperformance from one inverter, string, or section being low.
- Do not bypass safety controls or access rooftop and electrical equipment without appropriate qualifications.
What it depends on
- Persistence and extent of the production loss
- Monitoring data quality and system design
- Recent storms, maintenance, outages, or construction
- Warranty, service agreement, and provider response terms
Risks and trade-offs
- A temporary communications problem can look like production failure.
- Repeated resets or unsafe inspection can worsen damage or create shock and fire risks.
- Waiting can increase lost production or allow water, wiring, or thermal problems to worsen.
- A provider may need historical evidence to evaluate a performance guarantee.
Information you may need
- Clear-day production comparisons
- Monitoring screenshots, alerts, and timestamps
- System layout and recent event history
- Warranty and service contact information
Your next step
What to do next
Record the low-output dates and alerts, perform only the user-level checks in the system manual, and open a provider service request if the issue continues.
