How To Clean Solar Panels

March 31, 2023

Picture this: it’s a hot summer day, and you’re lounging on your deck, sipping a cold beverage, and basking in the sun. You look up and notice something that ruins your idyllic moment: your solar panels are covered in dirt and grime.

It’s a frustrating sight to see, but fear not my friends, for cleaning solar panels is easier than you think. As someone who’s cleaned more solar panels than I care to count, I’ve learned a thing or two about the process, and I’m here to share my insights with you.

Now, I know what you’re thinking. “Harry, I don’t have time to clean my solar panels. I have a life to live!” And believe me, I get it. But cleaning your solar panels is an essential part of maintaining their efficiency and ensuring they last for years to come. Trust me; I’ve seen too many people neglect their panels, and it always ends in tears.

Let me tell you a story about my friend Dave. Dave was the proud owner of a shiny new solar system, and he loved showing it off to anyone who would listen. But he made one fatal mistake – he never cleaned his panels. Fast forward a few years, and Dave’s once-impressive system was barely producing any energy. His panels were covered in dirt, bird droppings, and who knows what else.

Dave finally realized his mistake and hired a professional to clean his panels. But it was too late. The damage had already been done, and his system was never the same. Don’t be like Dave, my friends. Take care of your panels, and they’ll take care of you.

Now, let’s talk about how to clean your solar panels like a pro. First and foremost, safety is key. Before you start cleaning, make sure to turn off the power to your panels. And don’t try to clean your panels from a precarious position or without proper equipment. Trust me; falling off a roof is not worth a few dirty panels.

Once you’re safe and secure, it’s time to get down to business. Here’s what you’ll need:

Solar Panel Cleaning Equipment

  • A soft-bristled brush or sponge
  • A bucket of warm, soapy water
  • A squeegee or soft cloth
  • A hose or pressure washer (optional)
  • Non-abrasive, non-toxic cleaning solution

How To Clean Solar Panels

The cleaning process is reasonably simple. But, you need to be careful, and you need the right equipment. First, use a soft-bristled brush or sponge to remove any loose debris from the surface of the panels. Then, fill a bucket with warm, soapy water and use a soft cloth or sponge to clean the panels gently. Be careful not to use any abrasive materials or chemicals that could damage the panels.

Rinse the panels with a hose or pressure washer to remove any remaining dirt or soap residue. Finally, use a squeegee or soft cloth to dry the panels and remove any excess water.

Now, I know what you’re thinking. “Harry, this all sounds great, but what about the hard-to-reach spots? What do I do then?” Fear not, my friends. There are plenty of professionals out there who specialize in cleaning solar panels. So if you’re not comfortable doing it yourself, don’t hesitate to reach out to the experts.

Solar Panel Cleaning FAQs

How often should I clean my solar panels?

It’s recommended to clean your solar panels every 6-12 months, but this can vary depending on your location and the amount of debris that accumulates on your panels. If you live in a particularly dusty area, or a location with lots of trees overhead, you may need to clean your panels more frequently.

Can I clean my solar panels with just water?

While water can be effective in removing some surface dirt and debris, it’s usually not enough to get your panels completely clean. Using a non-abrasive, non-toxic cleaning solution will help to remove stubborn grime and ensure that your panels are running at optimal efficiency.

Can I use a pressure washer to clean my solar panels?

Yes, you can use a pressure washer to clean your solar panels, but you should be careful not to use too much pressure, as this can damage the panels. It’s best to use a low-pressure setting or to use a soft-bristled brush or sponge if you’re unsure.

Is it safe to clean my solar panels myself?

Chances are, if you’re asking this question – it may not be. Cleaning your solar panels can be a safe task if done correctly. However, it’s important to turn off the power to your panels before cleaning and to avoid using any abrasive materials or chemicals that could damage the panels. If you’re not comfortable cleaning your panels yourself, consider hiring a professional. (cough, Westy’s Pressure Washing)

Will cleaning my solar panels increase their lifespan?

Yes, regular cleaning can help to extend the lifespan of your solar panels. Removing dirt and debris from the surface of the panels can prevent microcracks from forming, which can affect the panels’ performance and lifespan over time.

Solar Panel Cleaning Tips

Now, I know some of you may still be hesitant to clean your solar panels, even after hearing Dave’s story. But let me tell you, the benefits far outweigh the effort it takes to clean them.

Not only will cleaning your panels ensure that they are running at optimal efficiency, but it can also help you save money on your energy bills in the long run. And let’s face it, who doesn’t want to save a few bucks?

Plus, cleaning your solar panels is a great excuse to spend some time outside and soak up some of that vitamin D. It’s a win-win, my friends.

But before you grab your cleaning supplies and head up to your roof, let’s go over a few more tips and tricks to ensure that you’re cleaning your solar panels safely and effectively.

Tip #1: Clean your panels in the early morning or late evening when they’re cool to the touch. This will prevent the soap from drying too quickly and leaving streaks.

Tip #2: Use a non-abrasive, non-toxic cleaning solution to avoid damaging the panels or harming the environment. There are plenty of eco-friendly options available, so do your research and choose wisely.

Tip #3: Be careful not to step on the panels or apply too much pressure when cleaning. This could cause damage to the panels and affect their energy output.

Tip #4: If you’re not comfortable cleaning the panels yourself, consider hiring a professional. They have the proper equipment and expertise to ensure that your panels are cleaned safely and effectively.

And there you have it, folks. Cleaning your solar panels may not be the most glamorous task, but it’s an important one. So grab your cleaning supplies, put on some sunscreen, and get to work. Your panels (and your wallet) will thank you.
