Five Tips For Maintaining Rooftop Solar Panels

Posted on: 17 June 2024


Maintaining your rooftop solar panels is essential to ensure they operate at peak efficiency and provide the maximum energy output. Regular maintenance helps prevent potential issues and prolongs the lifespan of your solar investment. Here are five tips to help you keep your rooftop solar panels in top condition.

Regularly Inspect Your Panels

To ensure your solar panels are functioning correctly, perform regular visual inspections. Look for signs of dirt, debris, or damage that might affect their performance. Pay special attention to cracks, chips, or discoloration in the panels. Inspect the surrounding area for any potential obstructions, such as overhanging branches that could cast shadows and reduce efficiency. Scheduling these inspections quarterly can help you catch and address problems early.

Keep Panels Clean

Dirt, dust, bird droppings, and other debris can accumulate on the surface of your solar panels, significantly reducing their efficiency. To maintain optimal performance, clean your panels regularly. Use a soft brush or a microfiber cloth to remove loose dirt, followed by a gentle rinse with water. Avoid using abrasive materials or high-pressure washers, as these can damage the panels. For stubborn spots, a mild, non-abrasive soap solution can be effective. Ideally, cleaning should be done in the early morning or late afternoon when the panels are cool to prevent water spots and streaks.

Monitor System Performance

Keeping an eye on the performance of your solar panel system can help you detect any issues early on. Most modern systems come with monitoring software that allows you to track their efficiency in real time. Look for significant drops in energy output, which can indicate underlying problems such as shading, dirt buildup, or technical malfunctions. Regular monitoring helps you address potential issues promptly, ensuring your system remains efficient.

Check for Physical Damage

Extreme weather conditions, such as hailstorms, high winds, or heavy snow, can cause physical damage to your solar panels and their mounting structures. After any severe weather event, inspect your panels and the surrounding area for damage. Look for signs such as bent or broken mounts, loose wiring, or panel misalignment. Address any damage immediately to prevent further complications and ensure the safety and efficiency of your system.

Schedule Professional Maintenance

While regular inspections and cleanings can be done on your own, it's also essential to schedule professional maintenance at least once a year. Professional technicians have the expertise and tools needed to perform comprehensive inspections, testing, and repairs that you might not be equipped to handle. They can check the wiring, inverter performance, and overall system health, ensuring everything works efficiently and safely.
