Maintaining your solar panels is essential to ensure their efficiency and longevity. In Cairns’ unique tropical climate, some basic, routine practices can help keep your solar energy system in optimal condition between professional maintenance visits. Here’s an in-depth guide to help you maintain your solar panels effectively.

Regular Cleaning

Dirty panels reduce the ability of the solar PV system to absorb sunlight, hence reducing the amount of power produced by the panels. In addition, solar panels feature electrical technology which demands regular maintenance in order to keep them up and working optimally for many years to come.

How Often Should You Clean Your Panels?

Owing to their nature and position, solar PV panels are often self-cleaning especially during the rainy season when much of the accumulated grime, dust and other dirt is washed away by rain water.

However, Hielscher Electrical’s Fact Sheets advises that any quality solar panel should be cleaned every six months. This should be done during the late autumn or the late spring, but households situated near areas of farming or construction activities should consider cleaning their solar panels more frequently. On the other hand, if you reside in an area that receives regular rainfall, you can reduce the frequency of cleaning or stop cleaning altogether. But whatever the case, ensure your solar panels are inspected by a reliable solar expert before your panels are cleaned.

Professional Cleaning Services

For those who prefer not to handle the cleaning themselves or have panels in hard-to-reach places, professional cleaning services are a great option. Hielscher Electrical offers comprehensive solar panel cleaning services to ensure your panels are maintained to the highest standards. Our team uses specialized equipment and techniques to safely and effectively clean your panels, maximizing their efficiency and lifespan. Regular professional cleaning can also include inspections to identify any potential issues early on.

Impact of Clean Panels on Energy Production

Clean solar panels are more efficient at converting sunlight into electricity, which directly translates into more energy production and greater savings on your electricity bills. Dust, grime, and bird droppings can significantly reduce the efficiency of your panels. By keeping your panels clean, you ensure that they operate at peak performance, providing you with the maximum return on your solar investment. Regular cleaning can lead to a noticeable increase in energy production, especially in areas with high dust or pollen levels.

Here My Helpful Solar Panel Cleaning Tips:

1. Turn Off the System: Ensure the solar system is turned off to avoid any electrical hazards.
2. Use Soft Tools: Use a soft brush or sponge and a hose to gently remove dirt and debris.
3. Avoid Pressure Washers: High-pressure water can damage the panels.
4. Dry Properly: Let the panels air dry or use a soft cloth to wipe them down.

Visual Solar Inspections

Routine visual inspections are a simple yet effective way to monitor the health of your solar panels. Look for physical damage like cracks, chips, discolouration, or warping. Check for any loose wiring or connections, and ensure the mounting frames are secure and free from corrosion.

Solar Inspection Checklist:

• Glass Surface: Check for cracks or chips.
• Wiring and Connections: Look for loose or exposed wires.
• Mounting Structure: Ensure it is firmly in place and not corroded.

Checking for Shade

Shade can significantly impact solar panel performance. Regularly inspect your installation for new shading issues caused by growing trees, new constructions, or other obstacles. If shading becomes a problem, you might need to trim trees or consider relocating your panels.

Steps to Manage Shade:

1. Identify Sources of Shade: Trees, buildings, or other installations.
2. Trim or Remove Obstructions: Trim back trees or remove other obstacles.
3. Panel Relocation: If shade issues persist, consider relocating your panels to a more exposed area.

Monitoring System Performance

Many modern solar systems come equipped with monitoring software that allows you to track performance. Regular monitoring can help you notice any significant drops in energy production, which could indicate a problem that requires further investigation.

How to Monitor Performance:

• Use Monitoring Software: Tools like SolarEdge or Fronius offer real-time data.
• Check Daily Output: Compare daily energy production to expected values.
• Look for Anomalies: Significant drops may indicate a need for professional inspection.

Keeping a Maintenance Log

Maintaining a log of all cleaning and maintenance activities, along with any observations or issues noted during visual inspections, can be very useful. A detailed log provides valuable information to maintenance professionals, aiding in quicker diagnosis and resolution of any issues.

What to Include in Your Log:

• Dates of Maintenance: Record when cleaning and inspections were performed.
• Observations: Note any issues or anomalies detected.
• Actions Taken: Detail the steps you took to address any problems.

Electrical and Solar Safety First

Safety should always be a priority when performing maintenance tasks. Ensure you have the necessary safety gear and are comfortable working at heights if you plan to clean or inspect the panels yourself. For safer and more thorough maintenance, consider hiring professional services.

Safety Tips:

• Wear Protective Gear: Use gloves, safety glasses, and non-slip shoes.
• Use Proper Equipment: Ensure ladders and other equipment are secure.
• Hire Professionals: When in doubt, hire a certified solar maintenance professional.
