Your solar panels work hard every day—don’t let dirt, mould, and bird droppings slow them down. The build-up of grime blocks sunlight, reducing energy output and costing you both efficiency and money.
Cleaning your solar panels is a simple, safe, and highly effective way to keep them running at peak performance. Using modern equipment, we remove the dirt and debris that diminish their efficiency, helping you prevent power loss and ensure they last for years to come. Regular solar panel cleaning is key to maximising both performance and longevity.
So, how much does solar panel cleaning cost? On average, solar panel cleaning ranges from $10 to $20 per panel, with larger homes typically paying around $480 or more. Want to know what drives those costs?
At i Clean Bundaberg, we’re here to help. We’ll provide a clear estimate, break down the factors that influence the price, and show you how clean solar panels can save you more in the long run. This guide will help you make the best decision for your home.
Estimated Cost of Solar Panel Cleaning
Before you book a service, it’s important to plan your budget. Here’s a standard price guide to help you:
| Number of Solar Panels | Estimated Cost |
|---|---|
| 20 panels | $240-$600 |
| 40 panels | $480-$1,200 |
| Over 40 panels | $500+ |
Now that you have an idea of the cost, let’s explore the factors that influence solar panel cleaning prices.
Factors That Influence Solar Panel Cleaning Costs
1. Property Location
Where you live and the type of property you own can impact the cost. City cleaning services are often pricier due to higher living costs and pollution, which can make solar panels harder to clean.
2. Solar Panel Placement
Ground-level panels are easier and cheaper to clean. Panels installed on steep or high roofs require special tools and safety measures, which can increase costs.
3. Solar Panel Condition
If your panels haven’t been cleaned in a while, heavy dirt and debris may require a deeper clean, adding to the cost. Dirt from animal waste, dust, leaves, and soot can accumulate quickly, making regular maintenance essential.
Latest Solar Panel Cleaning Methods
As technology advances, solar panel cleaning techniques have also evolved. Traditional cleaning methods like brushes, coatings and robotic cleaning devices have been modernised, making it easier and more efficient to clean panels.
1, Robot Cleaning
This is one of the most common and effective methods for cleaning solar panels. The latest development in this method uses a robot to control the brush, even without water.
2. Heliotex Cleaning System
Using installed sprinklers at various points in the solar plant, this device automatically sprays water onto the surfaces of the panels to clean them.
3. Electrostatic Cleaning
Electrostatic cleaning has become quite popular lately. It works by covering your solar panels with a clear, electrically charged sheet. When a high voltage is applied to this sheet, the dust is simply shaken off your panels.
4. Coating Method
Imagine covering your panels in a protective layer to keep them sparkling clean. That’s what coating methods do. There are two types of coating: hydrophobic and hydrophilic.
- Hydrophobic coatings: These coatings are like water repellents. Water forms tiny droplets and slides off, carrying dirt with it.
- Hydrophilic coatings: These are like sponges, soaking up water and washing away grime.
5. Vibration Cleaning Method
This method uses a machine called a mechanical vibrator to shake dust off your solar panels. Strong vibrations with force loosen the dirt, causing it to fly off.
6. Forced-Air Cleaning System
With the use of a blower through the panels, a forced-air cleaning system helps to remove dirt, dust and debris. By this method, solar panels can be cleaned with no sweat.
Pros and Cons of Cleaning Methods
| Method | Pros | Cons | Efficiency to Clean Panels |
|---|---|---|---|
| Robot Cleaning | Good option for all climates | Mechanic assemble is complex | 99.5% |
| Vibrating Cleaning System | Good when soiling is mainly due to dry dirt | Requires external power source for the motor | 95% |
| Manual Cleaning | Simple execution | Requires lots of consumables and manual labour | 90.67% |
| Forced-Air Cleaning System | Good when soiling is mainly due to dry dirt | Requires external power source for the air pump, and piping for the air distribution | 86.4% |
| Heliotex Cleaning | Effective for non-sticky dirt | Uses a lot of water | 12.5% |
| Hydrophobic and Hydrophilic Coating | Does not require extra consumables and labour | Coating hinders the panel efficiency by itself | 6.62% |
| Electrostatic Cleaning | Good for dry dust; doesn’t use mobile parts | Requires high voltage source, costly design | 3.35-11.5% |
Learning about the latest cleaning methods helps you discover which is most efficient and decide what is best for your solar panel care.
