Why Commercial Solar Panel System Maintenance Matters: Costs & Common Issues
Solar power has become an increasingly popular and sustainable energy solution for businesses across the UK. But just like any other long-term asset, solar systems require regular care and attention to keep performing at their best. That’s where commercial solar panel repair, servicing, and ongoing maintenance come in.
In this blog, we’ll explore why proactive solar PV maintenance is essential, what common issues might occur, the cost implications of neglect, and how your business can benefit from regular solar panel servicing.
Why Does Commercial Solar Panel Repair Matter?
Investing in solar panels is a smart decision for cutting energy costs; however, maintaining them is what ensures long-term return on investment. For commercial properties especially, system downtime can lead to significant financial losses in missed energy generation and, ultimately, higher bills.
Regular commercial solar panel repair helps:
- Optimise energy output
- Protect your business’s investment
- Extend the system lifespan
- Support your sustainability and net-zero goals
- Ensure compliance with warranties and insurance requirements
Routine servicing and timely repairs can prevent small issues from becoming larger and more expensive problems.
Common Commercial Solar System Issues
Understanding what can go wrong with a solar PV system will help your business stay ahead of potential problems. Some of the most frequent repair and servicing requests we handle at GGRS include:
Solar Inverter Repairs
The inverter is a crucial component of your solar PV system, converting DC electricity into usable AC. If your system isn't generating as expected, the inverter may be to blame. Common issues include:
Communication faults
- Overheating
- Ground faults
- Inverter failure after warranty

Panel Damage or Degradation
Cracks, hot spots, delamination, or water ingress can affect panel performance. This may be caused by:
- Environmental wear and tear
- Poor initial installation
- Animal interference (like birds nesting under panels)

Electrical Faults
Wiring issues, connection failures, or fuse blowouts are common in larger commercial systems and can lead to safety risks or a complete system shutdown.
Dirty or Blocked Panels
Dust, bird droppings, moss, and pollution can cause shading and lower output. Regular cleaning is often overlooked but can make a noticeable difference in system performance. Our professional solar panel cleaning service helps restore maximum efficiency.
