Solar Panel Maintenance: Essential for Longevity and Efficiency

Your solar panels are constantly exposed to the elements, from Perth's hot summers to dust, sea spray, and occasional rain. While solar panels are designed to be robust, regular maintenance and cleaning are crucial to ensure they operate at peak efficiency and provide maximum energy output throughout their lifespan. Neglecting your system can lead to reduced power generation, effectively costing you money.

Cleaning Your Solar Panels

The primary goal of cleaning your solar panels is to remove any accumulation of dirt, dust, bird droppings, or other debris that can obstruct sunlight and reduce efficiency.

• Frequency: In Perth, due to dust and occasional rainfall patterns, a general recommendation is to clean your panels every 6 to 12 months. Homes near busy roads, agricultural areas, or the coast might require more frequent cleaning due to higher dust or salt build-up.
• DIY vs. Professional Cleaning:
  • DIY Cleaning: For easily accessible panels, you can undertake cleaning yourself. Use a soft brush or sponge with plain water, or a mild, non-abrasive cleaning solution specifically designed for solar panels. Avoid harsh chemicals or abrasive tools that could scratch the panel surface. The best time to clean is on a cool, overcast day or early morning/late afternoon to prevent water from evaporating too quickly and leaving streaks. Always ensure your system is turned off before cleaning for safety.
  • Professional Cleaning: For panels on high roofs or those with difficult access, engaging a professional solar panel cleaner is highly recommended. They have the right safety equipment, specialized tools, and expertise to clean effectively without damaging the system or risking injury. Many professional cleaners also offer inspection services as part of their package.
• Impact of Dirt: Studies have shown that dirty solar panels can experience a significant drop in efficiency, sometimes as much as 15-20% or even higher in heavily soiled conditions. This directly translates to less electricity generated and higher electricity bills.

Regular Inspections and Troubleshooting

Beyond cleaning, routine inspections are vital to catch potential issues early and maintain optimal system performance.

• Visual Checks: Periodically inspect your panels from the ground for any visible damage such as cracks, chips, discolouration, or delamination. Look for signs of corrosion on the frame or mounting hardware. Also, check for any obstructions like overgrown branches or new structures that might be casting shadows on your panels at different times of the day. Shading, even partial, can drastically reduce a panel's output and affect the entire string in some systems.
• Performance Monitoring: Most modern solar systems come with monitoring apps or online portals. Regularly check your system's performance data. A sudden drop in output, inconsistent generation, or error messages are clear indicators that something might be wrong. Compare current output with historical data or expected generation for the time of year.
• Wiring and Connections: While best left to professionals during routine maintenance, be aware that loose or damaged wiring can impact performance and pose safety risks.
• When to Call a Professional: If you notice any physical damage, significant drops in performance not attributable to weather, or receive error codes from your inverter, it's time to contact a Clean Energy Council (CEC) accredited solar electrician. They can safely diagnose and repair issues, ensuring your system remains safe and efficient.

Maximising Your Investment: Understanding Solar Panel Performance in Perth

To truly maximise your solar investment in Perth, it's essential to understand how your system generates power and what factors influence its output. Solar panels convert sunlight into direct current (DC) electricity, which is then converted into alternating current (AC) by an inverter, making it usable for your home appliances.

The performance of your solar system is influenced by several factors:

• Sunlight Intensity: Perth enjoys high solar irradiance, making it an ideal location for solar power.
• Temperature: While sunshine is good, extremely high temperatures can slightly decrease the efficiency of some panels.
