The importance of solar panel cleaning for optimal performance

Solar panels are an essential investment for anyone looking to use solar energy to power their electrical appliances and depend less on electricity. However, to ensure that your solar panels are operating at peak efficiency, it’s ideal to keep them clean. Dirty solar panels can significantly reduce energy output, impacting your solar system’s overall performance.

Why you need to clean your solar panels 

Maximising solar panel efficiency

Solar panel efficiency can be affected by dirt. Even the big tech giant, Google, noticed that the energy output from their solar panels increased efficiently after cleaning them after being used for a period of 15 months. This is because, dust, bird droppings, and other debris can accumulate on the surface of the panels, blocking sunlight from reaching the cells and reducing their ability to generate electricity. Regular cleaning makes your solar panels free from these obstructions, allowing them to absorb as much sunlight as possible and convert it into solar power. According to the solar industry, panels may lose up to 5% of their efficiency if not cleaned properly.

Preventing long-term damage

Keeping your panels clean not only improves efficiency but also helps prevent long-term damage. Dirt and debris can cause scratches on the surface of the panels, which can lead to severe damage over time. Additionally, accumulated dirt can cause hotspots, which can further degrade the panels’ performance and lifespan. But with regular cleaning your solar panels, you can avoid these issues and extend the life of your solar installation.

Enhancing energy production

Clean panels are essential for maximising energy production. When solar panels are free from dirt and debris, they can generate more electricity, ensuring that you get the most out of your investment. This is especially important for residential solar systems, where every bit of energy production counts. Therefore, keeping your solar panels clean can reduce your reliance on grid power and lower your energy bills.

The best way to clean your solar panels

You may have noticed that your solar panels are not performing like they used to. This could be a result of poor maintenance, which can likely cause damage to the panels if left unchecked. Hence, cleaning of solar panels is a task worth doing to protect your investment. Let’s have a look at smart ways to clean the panels.

Using the right cleaning solutions

To clean your solar panels effectively, it’s important to use the right cleaning solutions. Harsh chemicals can damage the panels, so it’s best to use a gentle soap or a specialised solar panel cleaning solution. These solutions are designed to remove dirt and grime without causing any harm to the panels’ surface. Be sure to follow the manufacturer’s instructions for the best results.

DIY cleaning tips

If you prefer to clean your solar panels yourself, here are a few key tips to keep in mind. First, always turn off your solar system before cleaning to ensure safety. Next, use a soft brush or sponge to remove loose debris, and then gently wash the panels with a soapy water solution. Rinse thoroughly with clean water to remove any soap residue. Avoid using high-pressure water, as this can damage the panels. Even though DIY is a way to clean solar panels, you need to be very careful because you will be dealing with height, water, and electricity. Hiring a solar panel cleaning specialist is your best bet.

Hiring professional solar panel cleaners

For those who want the best results without the hassle, hiring professional solar panel cleaning services is a great option. Professional cleaners have the expertise and equipment to clean your panels safely and efficiently. They can also inspect your solar system for any potential issues, ensuring that your panels are in top condition. Professional cleaning is especially beneficial for large or hard-to-reach solar installations.

The benefits of professional solar panel cleaning

Expertise and experience

Professional solar panel cleaners have the knowledge and experience to clean your panels effectively. They understand the best cleaning methods and solutions to use, ensuring that your panels are thoroughly cleaned without any risk of damage. This expertise can save you time and effort while providing superior results.

Regular maintenance

Hiring a professional cleaning service also provides the benefit of regular maintenance. At Nanotech Coatings, we offer scheduled cleaning services, ensuring that your panels are cleaned at the optimal frequency. This regular maintenance helps keep your panels in peak condition, improving their efficiency and lifespan. 

What if I told you there’s a way to keep your panel clean for as lonag as 2 years without regular maintenance? 

Yes! There is. We will get to that shortly. Read on.

Safety considerations

Cleaning solar panels can be risky, especially for rooftop installations. Professional cleaners are trained to work safely at heights and have the necessary equipment to protect themselves. With professionals, you can avoid the risks associated with cleaning your panels yourself and ensure that the job is done safely and correctly.

How often should you clean your solar panels?

Factors affecting cleaning frequency

The frequency of cleaning your solar panels depends on several factors, including the local climate or your location, the amount of dust and debris in your area, and the angle of your panels. In areas with high levels of dust or pollen, or if you live near a busy road or construction site, your panels may require more frequent cleaning. Similarly, panels with aa shallow angle may collect more dirt and need to be cleaned more often. Also, if your panels are installed close to trees where birds frequently visit, you will have more bird droppings on your panels.

Recommended cleaning schedule

As a general rule, it’s recommended to clean your solar panels at least twice a year. However, you should monitor your panels regularly and clean them as needed. If you notice a drop in energy production or see visible dirt on the panels, it’s time to clean them. But, most times, these dirts can clean themselves through the natural effects of sunlight, rain and snow. Regular cleaning helps maintain optimal performance and ensures that your solar panels are always working efficiently.

The impact of clean solar panels on energy production

Increased efficiency

Clean solar panels are more efficient at converting sunlight into electricity. With little dirt and debris, you allow more light to reach the photovoltaic cells, increasing the panels’ efficiency. This boost in efficiency translates to more energy production and better overall performance for your solar system.

Cost savings

A well maintained solar panel can save you money on your energy bills. Increased efficiency means that your panels generate more electricity, reducing your reliance on grid power. Over time, these savings can add up, making regular cleaning a cost-effective way to maximise your investment in solar energy.

Environmental benefits

Clean solar panels contribute to a greener environment. With cleaner energy production, you reduce the need for fossil fuels and decrease your carbon footprint. Regular cleaning helps ensure that your solar panels are always performing at their best, allowing you to make a positive impact on the environment.

Keep your solar panels clean and efficient

Maintaining clean solar panels guarantees peak performance. You can choose to clean your panels yourself or hire professional services. By keeping your panels clean, you can ensure that your solar system is generating as much electricity as possible, saving you money and reducing your environmental impact.
