Solar Panel Maintenance: How to Keep Your System Performing at Its Best
Investing in solar energy is a smart, sustainable choice—but to get the most out of your solar system, regular maintenance is essential. Just like any technology, solar panels benefit from a bit of care to ensure they’re working efficiently year after year.
Whether you’re a new solar user or have had panels for a while, here’s how to keep your system in peak condition.
Why Solar Panel Maintenance Matters
Solar panels are designed to be durable and long-lasting, with many systems performing well for 25 years or more. However, dirt, dust, bird droppings, and even extreme weather can reduce performance if left unchecked.
A well-maintained system ensures:
Maximum energy output
Lower energy bills
Longer lifespan of equipment
Better return on investment
Cleaning Your Solar Panels
How often should you clean solar panels?
In most residential settings, panels should be cleaned once or twice a year—more frequently if you live in a dusty area or near trees.
Best time to clean?
Early morning or late afternoon, when the panels are cool. Cleaning them in the middle of the day risks cracking the glass from sudden temperature changes.
How to clean them:
Use a soft brush or sponge and a hose (never a pressure washer).
Avoid abrasive cleaning tools that can scratch the surface.
For stubborn dirt, a gentle detergent diluted in water will do the trick.
Tip: If panels are difficult to reach, consider hiring a professional cleaning service to avoid injury or damage.
Routine Visual Checks
Inspect your system periodically (ideally every few months) for the following:
Cracks or discolouration on the panels
Loose cables or exposed wiring
Inverter error messages or warning lights
Obstructions such as overgrown branches or fallen debris
These simple visual checks can help catch small issues before they turn into costly repairs.
When to Schedule Professional Inspections
While basic maintenance can be DIY, an annual check by a certified solar technician is highly recommended. A professional will:
Test the output and performance of your system
Inspect all electrical components
Ensure your inverter and battery (if applicable) are operating properly
Clean hard-to-reach areas
Many solar providers offer affordable maintenance packages or include inspections as part of their service plans.
