Troubleshooting the Sun: Common Issues with Solar Panel Systems for UK Businesses and How to Fix Them

So you’ve joined the renewable energy revolution, and your business is now proudly powered by a state-of-the-art solar panel system. Congratulations are in order! But as with any technology, hiccups can occur. In this blog post, we’ll explore some of the most common issues UK businesses face with their solar panel systems and offer guidance on how to troubleshoot these problems efficiently.

1. Decreased Energy Output: Where Did All the Sunlight Go?

One of the most common concerns is a sudden drop in the solar panels’ energy output.

Possible Causes: Dust and debris on the panels, or a malfunctioning inverter.

Quick Fix: Regular cleaning of the solar panels can work wonders. If the problem persists, check the inverter, as it’s the device that converts solar energy into electricity. It could be due for a replacement.

2. Inverter Issues: The Heartbeat of Your Solar System

If your inverter is showing error messages or fails to turn on, you’ve got a problem.

Possible Causes: Software glitches, internal fuses, or even age-related wear and tear.

Solution: Consult your inverter’s manual for troubleshooting steps specific to your model. If all else fails, contact the manufacturer or your installer for technical support.

3. Shading: The Cloudy Day Dilemma

An unexpected source of shading can drastically reduce the performance of your solar panels.

Possible Causes: New construction, tree growth, or even bird droppings can create shading issues.

Remedial Action: Trim back any encroaching trees and consider installing bird deterrents if birds are the culprits.

4. Solar Battery Problems: Holding onto the Sun

If you’ve got a solar battery system and it’s not storing energy as it should, this can be a significant issue.

Possible Causes: Battery degradation over time or a faulty charge controller.

Solutions: Check your battery’s warranty, as you may be due for a replacement. If your charge controller is the issue, consult the manufacturer for repair or replacement.

5. Micro-Cracks: Little Cracks, Big Problems

Micro-cracks can develop on the solar panels, affecting their structural integrity and performance.

Possible Causes: Extreme weather conditions or poor handling during installation.

Solutions: Inspect your panels regularly, and if you notice cracks, it’s time to call in the professionals. Many manufacturers offer warranties that cover such damage.

Resource Alert: The Microgeneration Certification Scheme (MCS) lists certified installers and products to ensure you’re getting top-notch quality and support for your system in the UK.

6. Water Leaks: When Solar Meets Rain

Water leaks around the solar panel mounting points can be a severe issue.

Possible Causes: Incorrect installation or deteriorated sealants.

Solutions: This is a job for the professionals. Call your installer to investigate and remedy the situation.

7. System Overheating: Too Much of a Good Thing

Believe it or not, too much heat can lower the efficiency of your solar panels.

Possible Causes: High ambient temperatures and insufficient airflow around the panels.

Solutions: Ensure there’s enough space around the panels for proper airflow and consider installing a cooling system if the problem persists.

In the Event of Issues: Your Action Plan

  1. Check Your User Manuals: They contain valuable troubleshooting steps.
  2. Consult Your Installer: They are your go-to for any installation-specific issues.
  3. Keep an Eye on Warranties: Ensure you know what’s covered so you can take advantage of free repairs or replacements if applicable.

The bottom line is that while issues can occur, they are generally fixable. Regular maintenance, visual inspections, and keeping your eye on the system’s monitoring platform can go a long way in preventing and quickly solving any problems. After all, the sun may go down, but your energy efficiency doesn’t have to.
