Image for 9 Things to Know for Cleaning Solar Panels After Foggy and Humid Weather

If you are a solar panel owner, then we have something interesting for you! Are you ready to know some tips on keeping your solar panels shining bright after those foggy and humid days? You should go through this whole article to learn more about it! 

The Impact of foggy and humid Weather on Solar Panel Efficiency: 

Okay, let’s start with the basics. Fog and humid weather can adversely affect your solar panels. When fog rolls in or humidity rises, a fine layer of residue can settle on your panels. The result is that this residue can block sunlight and worsen solar panel efficiency!  

Example: Suppose you’ve got a foggy week in Chino. Your solar panels soak up all the moisture and end up with a thin film of residue. As a result, they’re not working at their full potential, and you’re missing out on some precious energy savings! 

Why Solar Panel Care Matters: 

Before we begin with cleaning techniques, let’s discuss why it is so important to care for your solar panels. Just like you wouldn’t skip showering for days, your panels need some TLC too! Regular maintenance and solar panel care ensure they function at their best and last longer. 

Tackling Fog Residue and Boosting Performance: 

Now, here’s the exciting part – cleaning those panels! Remember, simple rain might not do the trick. You need a bit more than that to wipe away the stubborn residue. There is nothing to worry about as we’ll share some effective cleaning techniques with you!  

Example: Sarah notices her solar panels covered in fog residue after a week of gloomy weather in California. Instead of waiting for the rain to wash it off, she decides to give them a proper cleaning. With a gentle cleaning solution and a soft cloth, she restores their shine and sees a noticeable improvement in energy production. 

Weather Impact and Cleaning Frequency: 

You might wonder, “How often should I clean my panels after foggy or humid days?” Well, it depends. If you experience several days of these weather conditions, consider cleaning them every few weeks as the weather impact could be severe. But if it’s just a day or two, a monthly cleaning should suffice. 

Professional Help vs. DIY Cleaning: 

If you’re not into climbing ladders or dealing with cleaning solutions, you can always opt for our professional solar panel cleaning services in California. Our experts are equipped with the right tools and knowledge about cleaning your panels effectively and safely. However, if you’re the DIY type, just ensure you follow the right techniques to avoid damaging your panels.  

Cleaning Techniques That Work:  

When it comes to removing fog and humidity residue, gentle cleaning techniques are your best friends. Start by rinsing your panels with plain water to remove the initial layer of dirt. Then, mix a mild soap solution with water and gently scrub the panels using a soft cloth or sponge. Rinse them thoroughly to make sure no soap residue is left behind. This method is to clear the residue without harming the delicate solar cells. 

Spotting Signs of Residue Buildup: 

To determine if your panels need cleaning after foggy or humid weather, keep an eye out for signs. If you notice a hazy or dull appearance on the panels’ surface or a drop in energy production, it’s time for a cleaning session. Regular monitoring ensures you address any residue buildup promptly and maintain optimal efficiency. 

Maximizing Long-Term Benefits: 

Cleaning your solar panels after foggy and humid weather isn’t just a short-term fix; it’s a long-term investment. Regular maintenance doesn’t allow the residue to accumulate. This ensures that your panels consistently generate the maximum amount of energy. Your higher energy savings will give you a quicker return on your solar investment. If you can devote a little time to cleaning for better solar panel performance, then you can ensure a brighter and more efficient solar future for years to come. 

Eco-Friendly Cleaning Solutions: 

When cleaning your solar panels, consider using eco-friendly cleaning solutions. You may opt for biodegradable soaps and detergents that won’t harm the environment. This decision will make your solar energy eco-conscious and contribute to sustainable practices. Moreover, you can be satisfied as you’re not polluting the environment by introducing harmful chemicals while maintaining the performance of your panels. 


The bottom line is that fog and humidity might try to dim the shine of your solar panel. However, your proper care and cleaning can keep them performing at their best!
