Solar panels not only help reduce your energy bills but also contribute to a greener environment.

However, like any technology, the panels on your roof can face their fair share of challenges – and knowing how to fix these problems is key to keeping your costs down and maximising your savings

To help you quickly identify and resolve common solar panel problems, we’ll cover:

  • Why choosing the right panel is important
  • How to understand common solar panel problems
  • Simple solutions for the most common solar panel problems
  • Practical tips when you’re choosing new panels

Read on as we dive into the most common problems you might face with a home solar system.


  • Regular cleaning and maintenance maximises energy production and extends panel lifespan, preserves warranty.
  • Bird-proofing prevents damage to panels, maintains energy production and preserves rooftop aesthetics.
  • Proper panel placement maximises sunlight exposure, reduces shading issues, and boosts energy generation.
  • Upgrade ageing panels to restore panel efficiency, increase energy output and reduce long-term costs.

Why Choosing the Right Solar Panel Matters

Choosing high-quality panels and a reputable installation company from the outset can significantly reduce the chances of encountering these issues.

Quality panels are designed to withstand environmental challenges and come with warranties that offer peace of mind.

A reputable installation company will ensure proper placement, maintenance, and bird-proofing, helping you avoid costly repairs down the road.

Regular maintenance and cleaning are key to keeping your panels in top condition. Neglecting these simple tasks can result in decreased energy production and costly repairs.

Consider scheduling regular check-ups with professionals who understand the specific needs of panels in Adelaide’s unique climate.

Understanding Common Solar Panel Problems

Dust and Dirt Accumulation

Rooftop solar systems can sometimes come into contact with dust and dirt particles that settle on your panels. Over time, this layer of grime can reduce the efficiency of your panels, making them less effective in harnessing solar energy.

Regular cleaning and maintenance are vital to keep your panels performing optimally.

Bird Nests and Droppings

Birds often find the area beneath panels a cosy spot to build nests or leave their droppings.

These obstructions can hinder your panels’ efficiency and potentially damage them. Proper bird-proofing measures are essential to protect your investment.

Shading Issues

Trees and buildings can cast shadows on your panels, reducing their energy production. It’s crucial to consider your panel placement carefully to minimise shading issues and maximise sunlight exposure.

Panel Age and Degradation

Like all electronic devices, panels degrade over time. This natural aging process can lead to a decrease in their efficiency.

Keeping an eye on your panels’ performance and considering upgrades when necessary is essential to maintain optimal energy generation.

Solutions for Common Solar Panel Problems

Cleaning and Maintenance


  • Maximises energy production
  • Extends the lifespan of solar panels
  • Preserves your warranty

Dust and Dirt Accumulation:

Regular cleaning is essential to prevent the buildup of dust and dirt on your panels. A clean surface allows sunlight to be efficiently absorbed, maximising energy production.

Cleaning can be done with a soft brush, mild detergent, and a hose, or you can hire professional cleaning services for a thorough job.

Maintenance Tips:

  • Inspect your panels for any signs of damage.
  • Clean your panels at least twice a year, or more often if you live in a dusty area.
  • Check for loose connections and tighten them if necessary.



  • Prevents damage to solar panels
  • Avoids the disruption of energy production
  • Maintains the aesthetics of your rooftop

Bird Nests and Droppings:

To prevent birds from nesting under your panels, consider installing bird-proofing measures such as mesh or netting. These barriers deter birds from accessing the space beneath your panels while still allowing for proper ventilation.

You can also place reflective objects or noise devices nearby to discourage birds from landing on your roof.


  • Hire professionals to install bird-proofing measures for best results.
  • Regularly inspect for signs of bird activity and reapply deterrents if needed.

Proper Panel Placement


  • Maximises exposure to sunlight
  • Reduces shading issues
  • Boosts overall energy generation

Shading Issues:

Careful consideration of your panel placement during installation is crucial to avoid shading issues. Ensure that there are no nearby trees, buildings, or obstacles that cast shadows on your panels.

Solar tracking systems can also be used to follow the sun’s movement throughout the day, optimising energy capture.


  • Consult with an expert to determine the best placement for your specific location.
  • Periodically assess your surroundings for any new shading issues that may arise.

Upgrading Ageing Panels


  • Restores efficiency to aging panels
  • Increases energy production
  • Reduces long-term costs

Panel Age and Degradation:

As panels age, their efficiency naturally decreases. Consider upgrading to newer, more efficient panels to maintain optimal energy production. Modern panels often come with improved technology that offers higher performance and longer lifespans.


  • Monitor the performance of your panels regularly to identify when efficiency begins to decline significantly.
  • Consult with a specialist to discuss the benefits and feasibility of upgrading your panels.

How to Choose the Right Solar Panel Solution

Now that we’ve explored the common problems faced by solar panels and the solutions available, it’s time to delve into the factors you should consider when choosing the best option for your solar setup in Adelaide.

Location and Climate

Adelaide’s climate is known for its hot summers and mild winters. When selecting a solution for your panels, it’s essential to consider your specific location within Adelaide and the prevailing climate conditions.

If you live in an area with high dust or bird activity, prioritising regular cleaning and bird-proofing measures is crucial.

In regions with significant shading issues due to nearby buildings or trees, ensuring proper panel placement and possibly investing in solar tracking systems can make a significant difference.

Tailoring your solution to your location’s unique climate challenges will help you maximise energy production and minimise potential issues.

Budget and Cost-Efficiency

Budget constraints often play a significant role in determining the best solution. Cleaning and maintenance are relatively low-cost options, but they require regular attention.

Bird-proofing measures may involve a higher upfront cost but can provide long-term protection. Panel placement and upgrading ageing panels can have varying costs depending on your specific circumstances.

It’s essential to assess your budget and weigh it against the potential benefits and long-term savings each option offers.

While it may be tempting to opt for the most cost-effective solution initially, remember that investing a bit more upfront can lead to greater savings and efficiency over time.
