Signs Your Solar Panels Need Cleaning

& How MPV Solar Can Help

Solar energy is a smart investment, providing clean, renewable power while reducing your energy bills. To keep your solar panels operating at peak efficiency, regular cleaning is essential. But how do you know when it’s time for a professional clean?

Here are some common signs that your solar panels may need attention:

Significant Drop in Energy Production Despite Ideal Conditions

Your solar system monitoring app or device might show that your panels are producing less energy than usual, even when the weather conditions are optimal: clear skies, no clouds, and good sunlight. This discrepancy is often due to dirt, dust, or other contaminants blocking sunlight. Regular cleaning can restore your panels’ performance.

Visible Dirt, Dust, and Debris on the Surface

A quick visual inspection can reveal a layer of grime, bird droppings, leaves, or other debris on your panels. Over time, these contaminants accumulate and hinder sunlight absorption. If you notice a dull or streaky appearance, it’s time for a professional clean to enhance efficiency.

Screen or Monitoring System Alerts

Modern solar systems often come equipped with digital monitoring tools that notify you when energy output drops unexpectedly. These alerts can serve as early warning signs that your panels are dirty or obstructed, prompting timely cleaning before efficiency declines significantly.

Change in Panel Appearance – Dull or Cloudy Look

A clean solar panel typically has a shiny, reflective surface. When coated with dirt or grime, it can look dull or cloudy. This visual change reduces sunlight absorption and indicates the need for cleaning.

Accumulation of Environmental Particles

In areas prone to dust storms, pollen, bird activity, or pollution, panels can quickly become coated with particles. If you notice pollen or dust settled on the surface, especially after periods of windy or dry weather, professional cleaning can prevent reduced efficiency.

Reduced Power Generation After Storms or Windy Days

Storms and high winds can kick up dirt, leaves, and debris that settle on your panels. Even if the panels are physically unaffected, the buildup can impair performance. Regular cleaning after such events helps maintain optimal energy output.

Reduced Return on Investment (ROI)

If your solar system isn’t performing as expected, cleaning might be a simple yet effective step to maximise your ROI. Dirt buildup can cause as much as a 20% loss in energy production, which directly impacts your savings.

Book a Solar Panel Clean

Regular panel cleaning is essential for maximising power output, enhancing both efficiency and performance, and increasing the lifespan of your panels, ensuring you get the most out of those sunny days.

FAQs about Important Tips for Removing Solar Panels

Your questions about removing solar panels answered.

How often should I clean my solar panels?

Typically, solar panels should be cleaned at least once or twice a year. However, in areas with high dust, pollen, bird activity, or pollution, more frequent cleaning, every 3-6 months is recommended to maintain optimal efficiency.

Can I clean my solar panels myself?

Yes, cleaning your panels yourself is possible using soft brushes or sponges with water. However, to avoid damaging the panels or voiding warranties, it’s best to hire professional solar panel cleaners like MPV Slolar who use specialised equipment and eco-friendly cleaning solutions.

Will cleaning my solar panels damage them?

When done correctly by trained professionals, cleaning will not damage your panels. Using improper techniques or harsh abrasives can cause scratches or other damage, which is why it’s advisable to rely on experienced service providers like MPV Solar.

Is cleaning solar panels necessary in cloudy or rainy weather?

Cloudy or rainy weather can help wash away some dirt naturally, reducing the need for cleaning. However, ongoing dirt buildup from other sources still requires periodic cleaning to maintain maximum efficiency.

How much does professional solar panel cleaning cost?

Costs vary depending on the size and accessibility of your system, as well as your location. On average, professional cleaning services range from $250 to $500 plus GST. It’s a worthwhile investment to ensure your system performs optimally and lasts longer.

Do dirty solar panels affect my energy production significantly?

Yes. Dirt, dust, and debris can cause a reduction in energy output by up to 20% or more, depending on the level of contamination. Regular cleaning ensures your system operates efficiently and maximises your energy savings.
