Your solar panels convert sunshine into sustainable energy every single day. No noisy buzzing, no regular maintenance. There are not even any moving components to worry about. But even though they’re low-maintenance, they’re not no-maintenance. They still need some regular care. What can you do to keep them running smoothly for years to come? Let’s find out.

 

Solar Panel Maintenance – keeping clean

Over time, dirt, dust, bird droppings, pollen and leaves can build up on the surface of your panels. When sunlight can’t reach the cells properly, it reduces your system’s ability to produce energy efficiently. Even a thin layer of grime can make a difference.

Most of the time, nature does the job for you. A decent bit of rain will wash away surface dirt. But you might need to step in in drier months or if your panels are under trees. If your energy output seems lower than usual or you notice visible buildup, it’s time for a clean.

Use lukewarm water, mild detergent, and a soft sponge or brush. Skip the pressure washer or abrasive tools since they can damage the panel surface. If your roof is high or steep, call in a professional cleaner. It’s better to spend a little extra than risk a fall.

 

Monitor Your System’s Performance

Most solar systems today come with an app or online portal. These let you see how much energy your system generates daily, weekly, and monthly. Watch for any unexpected decreases in output. It’s worthwhile looking into why your system suddenly starts producing 12 or 14 kWh per day when it normally produces 20. Simple things like dirt on the panels or an unusual shade might be the cause. Alternatively, it can indicate a problem with one of the panels, the wiring, or the inverter.

 

Book Annual Inspections

Your solar panel system requires an annual inspection. A certified professional can check your inverter, mounting brackets, wiring, and overall system performance. They will also search for any indications of deterioration, such as loose joints or weather-related harm. 

A good inspection gives you peace of mind and validates your manufacturer’s warranty. If your system includes a battery, this is even more important. Battery systems need special checks to ensure they’re charging and discharging properly.

 

Watch for New Shade

Your solar panel system might have been installed in full sun, but that doesn’t mean it will stay that way. Trees grow and neighbours build extensions, which can cast new shadows over time. Solar panels rely on direct sunlight, so any shading, especially during peak sun hours, can affect performance. 

Check in every few months to make sure nothing has changed. A trim might be in order if a nearby tree is creeping into your panels’ sun path and if something more permanent is blocking the light, ask a professional about solutions.

 

Check Inverter Lights and Error Messages

Your inverter converts the DC power your panels produce into usable AC power for your home or business. Most inverters have a display, or indicator lights, that show the system’s status. A green light? All good. Flashing red or an error code? Something needs attention. Don’t ignore error messages. That’s your system asking for help. It could be a minor fix, but left unchecked, it might affect your system’s output or safety.

 

A Little Care Goes a Long Way

With just some regular attention, your solar panels can run efficiently for 25 years or more. Clean panels and routine inspections give better performance and lower energy bills. Not sure where to start? That’s what we’re here for!
