Routine cleaning averts the accumulation of dirt, which harms the protective coating of the panels. Cleaning the panels routinely makes them more durable and preserves their performance.
Lowering Maintenance Expenses
Panels that are cleaned often are less likely to need expensive repairs. Dirt can cause problems, but cleaning can help avoid these issues and save money on future repairs. Cleaning regularly is a cheap way to take care of your panels.
When and How Often Should You Clean Solar Panels?
Due to their high photovoltaic conversion efficiency and smooth surface, mono silicon panels may require less frequent cleaning compared to polycrystalline or thin-film panels. But the frequency of cleaning your mono silicon solar panels is still affected by various factors such as the environment, the season, and the location of the panels.
When to Clean
After Storms or High Winds: Severe storms or strong winds can carry leaves, dust, and even tiny branches. These may settle on the surface of the panels and obstruct sunlight. A quick wash is advisable following such occurrences to restore the efficiency of the panel.
Seasonal Changes: Each season also brings its own set of challenges for the solar panels. During spring and fall, pollen and fallen leaves can be problematic since they can potentially obstruct sunlight should they be left on the panels for a long time. To ensure maximum performance, it is recommended to clean the panels in these seasons.
When Performance Declines: If your panels are not producing energy at their normal capacity, the reason could be a dirt or debris accumulation. Even if there is no apparent grime, if you notice that your performance is decreasing, it is still a good idea to clean the panels.
How Often to Clean
- Environmental Factors: In areas that are susceptible to dust storms, torrential rains, or environmental elements that deposit pollutants on the surface, a good cleaning once or twice yearly should be enough.
- Panel Angle: Solar panels that are installed at flatter angles have a higher propensity to collect dust and dirt and, as such, might have to be cleaned more frequently than their steeper-angle-installed counterparts.
- Personal Judgment: You can also rely on your own judgment based on what you see. If the panels are obviously dirty or performance is considerably less than it should be, it's time to clean them. For most places, cleaning once or twice a year is usually enough.
Solar Panel Cleaning Kit
It is important to have the appropriate tools to clean mono silicon solar panels properly. Improper cleaning techniques or tools can cause scratches and other types of damage that reduce the efficiency of panels.
4 Tools You Need
- Soft Brushes: A soft brush won't scratch as it removes the dirt. Avoid using hard brushes or metal scrubbing pads because they scratch and harm the panel's surface.
- Microfiber Cloth: This product is ideal for cleaning solar panels as it easily removes smudges and fingerprints without causing any damage.
- Telescopic Pole: For hard-to-reach panels, a telescopic pole can help you clean the surface safely without the need to climb on the roof, reducing the risk of accidents.
- Water Hose or Sprayer: Water is one of the easiest and safest ways to remove dirt from the surface of the panels. A gentle flow of water will remove most debris without damaging the panel's surface.
Cleaning Solution
Use Gentle Solutions
Use distilled water or a mild, neutral cleaning solution to wash your panels. Distilled water contains no minerals that will leave deposits on the surface of the panel.
Avoid Using Strong Acidic or Alkaline Cleaners
Abrasive cleaners, such as strong acids or alkaline cleansers, will corrode solar panels. Over time, this will decrease the efficiency of the panel and reduce its lifespan. Gentle cleaning solutions should be used to maintain the integrity of the panels.
Effective Methods for Cleaning Solar Panels
Mono silicon panels usually have a smoother surface, higher efficiency, and better resistance to contamination. During cleaning, the surface is less likely to accumulate large amounts of dirt and dust compared to other types of panels, making the cleaning process relatively simple. But learning the right cleaning techniques ensures that your solar panels remain in top shape. Here's a step-by-step guide on how to clean your solar panels effectively without causing damage.
4 Cleaning Steps
Check the Panels
Prior to cleaning your solar panels, take a good look to see if you can find any damage on them. Look for cracks, loose connections, or any wear and tear that might interfere with the performance of the panel. If you do find any of these problems, your best option is to call a professional to examine and repair them further. Solar panels are fragile, and trying to clean or repair damaged panels on your own may result in additional damage.
Use Soft Brushes to Remove Dust
The initial step in the cleaning of your solar panels is to take a soft-bristled brush and gently sweep off any dust, dirt, or debris that may have settled on the surface. A soft-bristled brush should be used to avoid scratches. Metal scrubbers and hard brushes can lead to permanent damage to the surface of the panel, which can lead to inefficiency. Brush gently—do not push too hard to avoid causing any damage to the panels.
Spray with Water
Once the dust is removed, spray the panels using a hose with a soft stream of water or a sprayer. Water can dislodge stubborn dirt like bird droppings, leaves, or mud. Take care not to use a high-pressure hose. Although mono silicon panels are structurally strong and can withstand some cleaning pressure, high-pressure water should still be avoided. A low-pressure spray is enough to rinse off most of the dirt. It's also important not to spray water directly on electrical parts or connections on the panels.
Wipe the Panels
Following spraying with water, wipe the panels with a microfiber cloth to eliminate excess moisture. Microfiber cloths are best for this purpose since they are soft on the surface and will not leave lint or streaks. Wiping the panels will make sure there is no water residue or dirt left behind, which can otherwise impact the performance of the panels. Make sure the surface is thoroughly dry to avoid water spots.
Check the Cleaning Results
After you've finished cleaning, take a moment to inspect the panels again to ensure that no dirt, debris, or water residue remains. This is an important step, as even small amounts of residue can affect the solar panel's efficiency. Check from different angles to ensure you haven't missed any spots. If the panels still look streaky or dirty, repeat the cleaning process until they are completely clean.
Using the right tools and gentle methods ensures that your cleaning process doesn't damage the panels. If you're cleaning solar panels regularly, a product like the EcoFlow 400W Portable Solar Panel could be a great fit. Its self-supporting design and adjustable angle allow you to position the panel at the perfect angle for cleaning, ensuring it is always operating at its peak performance.
