Solar panels are a fantastic investment for clean energy and long-term savings. However, like any technology, they can occasionally experience issues that affect performance. The good news is that most solar panel problems are minor and easily resolved with proper knowledge and maintenance.
In this guide, we’ll explore some of the most common solar panel issues, how to identify them, and what you can do to troubleshoot effectively. Whether you're a homeowner, business owner, or solar enthusiast, this quick guide will help keep your system running smoothly.
And remember—choosing high-quality panels, like those from PRBS, a professional manufacturer of premium solar panels, significantly reduces the likelihood of problems in the first place.
1. Low Power Output
Symptoms:
Your solar system is producing less energy than expected.
Possible Causes:
Dirty or shaded panels
Faulty inverter
Wiring issues
Aging panels
Troubleshooting Tips:
Clean your panels regularly—dust, leaves, and bird droppings can block sunlight.
Check for shading, especially during different times of the day or year.
Use your monitoring system to verify if one panel or the entire array is underperforming.
Consult your installer to inspect inverter status lights and ensure all connections are secure.
2. Inverter Problems
Symptoms:
Error messages or red lights on the inverter, no energy output despite sunny weather.
Possible Causes:
Software bugs
Faulty components
Grid disconnection
Troubleshooting Tips:
Reset the inverter (follow the manufacturer's instructions).
Check that your solar system is still connected to the grid.
Read the error code and consult your installer or the inverter manufacturer.
PRBS panels are fully compatible with most modern inverter systems and undergo strict quality testing to minimize incompatibility issues.
3. Wiring or Connection Failures
Symptoms:
Fluctuating performance, system intermittently shutting down.
Possible Causes:
Loose or corroded wires
Water ingress
Poor installation practices
Troubleshooting Tips:
Inspect visible wiring for damage or looseness (do not attempt to fix live systems).
Ensure weatherproofing is intact.
Have a certified technician perform a full system inspection.
PRBS uses high-grade materials and connectors in our solar panels to ensure long-lasting, secure electrical connections.
4. Hot Spots and Micro-Cracks
Symptoms:
Panels show discoloration or burn marks; unexpected performance drops.
Possible Causes:
Manufacturing defects
Hail or heavy impact damage
Poor ventilation
Troubleshooting Tips:
Use an infrared camera or thermal imaging to identify hot spots.
Regularly inspect panels, especially after storms.
Contact your manufacturer if you suspect a defect.
All PRBS panels undergo rigorous testing—including thermal cycling and impact resistance—to prevent micro-cracks and hot spots.
5. Monitoring System Failures
Symptoms:
Inaccurate or missing data on your solar app or platform.
Possible Causes:
Faulty sensors
Software bugs
Internet connectivity issues
Troubleshooting Tips:
Reboot your monitoring device or app.
Check your Wi-Fi connection.
Update your software or firmware if necessary.
PRBS recommends pairing our panels with smart monitoring systems for real-time insights and early issue detection.
6. Weather-Related Performance Drops
Symptoms:
Lower energy production during cloudy, rainy, or snowy weather.
Explanation:
This isn’t a fault—it’s a natural result of reduced sunlight. However, quality panels can still generate power even in poor weather.
