If your solar panel system isn’t performing as efficiently as it should, it may be time for a service or repair.

Regular maintenance ensures your solar setup continues generating maximum renewable power.

Solar panel servicing vs full replacement

• Servicing/repair: Ideal for maintaining efficiency, extending lifespan, and preventing bigger faults. It’s typically inexpensive and quick to complete
• Replacement: Often best if panels are more than 15–20 years old or repeatedly underperform. New panels may improve efficiency and qualify for updated warranties

A qualified solar panel engineer can test each component and let you know if repair or replacement is the best long-term option.

How long do solar panels last?

High-quality solar panels usually last 25 years or more, though inverter components may need replacing sooner.

What are the benefits of regular solar panel servicing?

Benefits of regular solar panel servicing include:

• Maximised energy efficiency and lower electricity bills
• Early detection of electrical faults or damage
• Compliance with manufacturer warranties
• Improved system safety and reliability

Maintenance of solar panels

To keep your solar panels performing efficiently:

• Schedule a solar panel clean and inspection every 1–2 years
• Check for dirt, debris or bird droppings that block sunlight
• Keep nearby trees trimmed to avoid shading

Never attempt to inspect your roof-mounted solar panels — always hire a qualified solar panel engineer for safe roof-access cleaning and system testing.
