Sparkling Clean: Your Ultimate Guide to Solar Panels Cleaning

Solar energy is a fantastic way to harness the power of the sun while reducing your carbon footprint and saving on electricity bills. However, like any other investment, solar panels require some care and maintenance to perform at their best. Solar panels cleaning is an essential part of the maintenance. In this article, we will dive into why, when, and how to clean your solar panels to keep them running efficiently for years to come.

Why Do You Need to Clean Solar Panels?

Solar panels need cleaning for maximize energy production. Any buildup of dirt, dust, or grime can hinder efficiency, known as soiling, which can reduce sunlight absorption by up to 7% annually in some regions. While natural rainfall can often keep panels clean, periodic thorough cleaning offers significant advantages.

Clean panels capture more sunlight, leading to increased energy production and potentially lower electricity bills. Additionally, removing debris helps maintain the panels' integrity, prolonging their lifespan. Regular cleaning also enhances overall system performance and allows you to identify potential issues like cracks or damage before they escalate.

How Often Should Solar Panels Be Cleaned?

Cleaning your solar panels can be done once or twice a year, although this can vary based on your location. For instance, if you reside in a rainy area, you may not need to clean them as often compared to a place that experiences dry, dusty conditions with significant debris accumulation.

In desert climates, such as parts of the Southwestern United States, more frequent cleaning is necessary due to the buildup of dust and sand, which can hinder solar system performance.

Areas close to highways, factories, and airports are often subject to higher pollution levels. Therefore, it's advisable to clean solar panels more regularly in these locations.

Additionally, if you live in a region with dense tree cover, it's important to clean the panels frequently to remove any overgrown vegetation or bird droppings that may obstruct sunlight.

How to Clean Solar Panels?

Cleaning solar panels is not a difficult task, but it does require some care to avoid damaging the panels. Let’s explore two popular approaches: DIY cleaning and hiring professional services.

Professional Cleaning Services

While you can certainly handle solar panel maintenance on your own, sometimes it is worth considering professional cleaning services for added convenience and safety. Hiring experts can ease your mind about the process, particularly if the panels are located on the roof.

• Safety and expertise: Professional cleaners are trained to work at heights and are familiar with the best practices for cleaning solar panels.
• Cost consideration: Hiring a professional typically costs between $150 and $300, which breaks down to about $15 to $30 per panel.
• Variety of services: There are different types of professional cleaning services available. Some use semi-autonomous robots to clean panels with minimal human intervention, while others employ soap-less brushes to eliminate the risk of harmful residues. Cutting-edge methods, like waterless vibration technology, are also being developed to enhance cleaning efficiency. 

Common Mistakes to Avoid for Solar Panel Cleaning

Cleaning solar panels is a straightforward task, but there are some common mistakes that can damage your panels or reduce their efficiency. Let us go over the top mistakes to avoid.

• Cleaning in direct sunlight: Avoid cleaning your panels on a hot, sunny day. The extreme heat can cause the water to evaporate quickly, leaving streaks or spots behind. Early morning or late evening are the best times for cleaning, as the panels will be cooler, and you’ll avoid direct sunlight.
• Ignoring safety precautions: If your solar panels are on the roof, ensure you have the right equipment, like a stable ladder and harness if necessary. Never put your safety at risk whencleaning your panels.
• Lack of proper experience: Attempting to clean solar panels without the necessary experience or training can result in damage to the panels or personal injury. It’s safer to hire a professional to ensure effective and safe cleaning.
