Solar Panel Cleaning: Should You Hire a Professional Cleaner?

Introduction

Cleaning your solar panels impacts their ability to absorb sunlight and convert it into usable energy. Any obstruction preventing sunlight from reaching the silicon on the panels can affect your system's performance.

Solar panels installed with a sufficient tilt will naturally clean themselves during heavy rainfall, thus, when is it necessary to clean your solar panels and what is its significance?

Numerous Australian homeowners ponder the process of cleaning solar panels and its effect on their system's performance. The most common query revolves around the value of employing a solar cleaning service. This article elucidates essential aspects to consider.

Is it Worth Cleaning Your Solar Panels?

Dirty solar panels may lead to decreased power output as dirt, dust, or debris accumulates on their surface. The degree of power reduction can fluctuate based on factors like dirt level, panel angle, orientation, local dirt type, and buildup duration.
Studies suggest that dirty solar panels may encounter power decreases of 5% to 35% on average. Nonetheless, it's crucial to acknowledge that these figures are rough estimates, and various factors can impact the actual power loss.
Consistent upkeep and cleaning of solar panels are vital to enhance their efficiency and power production. Maintaining clean panels, devoid of debris, guarantees they operate at peak performance, generating the utmost electricity.

Factors Affecting Solar Panel Efficiency?

Impact of Debris

Accumulated dirt and debris on solar panels can lead to notable energy production declines. These particles obstruct sunlight penetration, lowering the panel's energy conversion rate. Hence, regular cleaning is essential to maintain optimal energy production.

Seasonal Considerations

Various seasons pose distinct challenges for solar panel maintenance. Winter snowfall can entirely cover panels, autumn brings fallen leaves, and spring introduces pollen. Each season requires a tailored cleaning approach to uphold panel efficiency

Different environments and locations are subject to worse soiling than others.

What Makes Solar Panels Dirty?

Bird Droppings- While a single bird dropping may not notably impact output, accumulations over time can substantially decrease it. Rainfall alone is often inadequate for cleaning bird droppings.
Dirt Accumulation Around the Frame- Even though rainfall typically removes most dirt from solar panels with a tilt of 10 degrees or more, dirt often accumulates around the aluminum frame. This accumulation can result in losses and the development of hotspots.
Debris- If you have trees nearby or face strong winds, larger debris may gradually get stuck between the panels, leading to shading and affecting the system's output over time.
Fungi, Lichen or Mold- Just as you can encounter growths on your roofing sheets or tiles, you can anticipate similar occurrences over time on your solar panels.
Particulate exhaust or dust- If you reside in an industrial area, you might notice nearby factories emitting byproducts that adhere to solar panels, making them challenging to clean.

When to Clean Solar Panels?

As a general guideline, it is advisable to clean solar panels at least once every 2-3 years to uphold their optimal performance.

The frequency of cleaning residential solar panels can vary depending on factors such as your location, weather conditions, and the environment surrounding your home.

Removing daily dust from solar panels typically occurs naturally during heavy rainfall if the panels are installed at a tilt. Therefore, cleaning solar panels is generally necessary in areas where heavier soiling is present.

Signs that Your Solar Panels Require Cleaning?
