Troubleshooting Your Solar Panels: Common Issues and Solutions

Understanding Solar Panel Problems

Solar panels are a fantastic investment for your home. However, like any technology, they can encounter issues. Knowing how to troubleshoot these problems can save you time and money.

1. Inverter Faults

Inverters are the heart of your solar system. Common brands like Solis, Sunsynk, and GivEnergy sometimes fail due to blown fuses, firmware bugs, or configuration errors. A flashing red light or no lights at all usually means it’s time to call in an expert.

Signs of Inverter Issues

• Flashing red light

• No lights at all

• Inconsistent energy output

  
  

If you notice any of these signs, it’s crucial to act quickly.

2. Loose or Damaged Cables

Rodents can chew through cables, or MC4 connectors may become loose due to poor installation. If your app shows low or zero output, cable damage might be the cause.

How to Check for Cable Issues

• Inspect visible cables for chew marks or wear.

• Ensure connectors are securely fastened.

• Use your monitoring app to check for output levels.

  
  

3. Shading and Dirt Buildup

Even a few leaves, pigeon mess, or lichen growth can block solar production. Check your panels if safe to do so or book a maintenance check.

Cleaning Your Solar Panels

• Remove any debris from the surface.

• Schedule regular maintenance to keep panels clean.

• Consider professional cleaning services if needed.

  
  

4. “System Offline” on Your App

If your monitoring app says the system is offline, check your Wi-Fi and inverter status first. If the inverter is working but offline, it could be a router issue. If not, your system might be completely disconnected.

Steps to Resolve Offline Issues

• Restart your Wi-Fi router.

• Check inverter connections.

• Contact your installer if the issue persists.

  
  

5. Check the Consumer Unit

Tripped breakers or isolated fuses can cut power to your system. A simple reset might solve the problem, but only do this if you feel confident and it’s safe.

Troubleshooting the Consumer Unit

• Locate your consumer unit.

• Check for tripped breakers.

• Reset any tripped switches carefully.
