How to keep your solar panels performing

Keeping your solar panels performing at their best is essential. With energy prices rising and the long-term return on solar being tied to efficiency, it’s important to protect your system from performance drops. Fortunately, a few simple steps can make a big difference.

Regular cleaning makes a big difference

Cleaning your solar panels regularly is one of the easiest and most effective ways to maintain output. 

Dust, leaves, bird droppings and grime can block sunlight, reducing the system’s ability to convert solar energy into electricity. While rain might wash off some debris, it won’t give panels a proper clean. This is where professional solar panel cleaning comes in. In Melbourne’s urban, coastal and regional areas, we offer solar panel cleaning services that remove build-up without damaging your system, helping restore efficiency and output.

System health checks

System health checks are another key part of long-term maintenance. These inspections cover the condition of your panels, wiring, inverter, and overall system performance. Faults or wear aren’t always obvious to the eye, and issues like panel degradation or loose connections can quietly reduce your energy yield. Our solar panel health checks help detect and resolve problems before they become expensive repairs or impact your energy savings.

Bird proofing is also an important but often overlooked step. Birds nesting under panels can cause wiring damage and leave droppings that create hotspots, both of which reduce performance. Bird proofing can prevent this, using weather-resistant mesh to keep birds out without interfering with panel airflow or roof integrity. It’s a one-time solution that protects your system year-round, starting from just $15 per metre.

Alongside professional services, it helps to monitor your system regularly. Many solar inverters and monitoring apps let you track output and spot irregularities. If you notice a sudden dip in production, it might be time to check for debris, damage, or system faults. While some homeowners attempt DIY maintenance, there are limits to what you can do safely and effectively. Working at heights and handling electrical components carries risk. By working with experienced solar technicians, you’re investing in long-term performance, safety and peace of mind. Book a service now with Cleantek and keep your solar system performing at its peak.
