Common Solar Panel problems

As with anything, there are many ways that solar panels may malfunction. The best way to determine what has gone wrong would be to contact a professional (such as the provider/engineers who initially installed them for you). 

Common solar panel issues may include:

  • Not generating electricity
  • Generating less electricity than expected
  • An inverter or other component developing a fault
  • Incorrect installation of the panels
  • Faulty monitoring equipment
  • The installation doesn’t meet the agreed specifications

REMEMBER:

It’s important not to assume that a reduction in electricity generation automatically means the panels are faulty. Solar panel electricity generation can vary depending on factors such as weather, daylight hours, shading and the condition of the system.

If you’re concerned that your solar panels aren’t performing as they should, your first step should be to contact the company that installed or supplied it to submit a formal complaint.

Before submitting a Solar Panel complaint…

Before reaching out to the provider who installed the panels for you, it’s usually worth gathering evidence in preparation to strengthen your complaint and increase its chances of success.

Here’s what we recommend you should do!

1. Check your Solar Panels

No matter what your complaint is about, it’s always worth gathering some basic information that clearly demonstrates what went wrong, and eliminates any room for confusion.

For example, you might want to check and make note of:

  • When you first noticed the problem
  • How much (if any) electricity the solar panels are generating
  • Whether your inverter or monitoring system is displaying an error
  • Whether the problem is constant or intermittent
  • Whether any equipment appears damaged

It can also be useful to take photographs or screenshots of error messages, monitoring information or any visible issues.

Don’t attempt to repair electrical equipment yourself! 

If you believe there may be an electrical fault or safety issue, it’s always advisable to contact an appropriately qualified professional to carry out any repairs. Not only is it safer, but if you try and fix the issue yourself and accidentally damage anything further, you could also make it harder to prove who was liable for the issue in the process.

2. Check your paperwork

Before contacting the installer, locate any documents relating to your solar panel installation. 

This could include:

  • Your contract or order confirmation
  • The installation specification
  • Invoices or receipts
  • Guarantees or warranties
  • Details of any maintenance or servicing agreement
  • Emails or messages exchanged with the installer
  • Information about the system’s expected performance

What was promised? What did you agree to originally? 

These documents can help you establish what you were told you were purchasing and what services the company agreed to provide.

3. Contact your solar panel installer

Finally, after having gathered the relevant evidence and made a clear account of events, your next step should normally be to give the provider an opportunity to investigate and resolve the problem.

Filing a formal complaint with the provider and giving them an opportunity to put things right is usually a key requirement for most forms of complaint escalation later down the line – such as using Alternative Dispute Resolution (ADR), or going to court.

For example, you may ask them to:

  • Inspect the system
  • Repair or replace faulty equipment
  • Correct an installation problem
  • Investigate why the system isn’t generating as expected
  • Provide information or documentation that you were promised
  • Refund or compensate you where appropriate
