Answered: Does Windex Damage Solar Panels

Many solar panel owners wonder if using Windex to clean them is a good idea. This question comes up quite often due to the common use of Windex in cleaning traditional glass surfaces. However, it’s important to remember that the materials used in creating solar panels differ significantly from standard windows.

Solar panel manufacturers usually recommend against using soap-based cleaners such as Windex. Why’s that? Well, these types of cleaners have a propensity to leave streaks on the panels. Streaks may appear harmless, but they can actually reduce your panels’ efficiency by reflecting sunlight, instead of allowing it to be absorbed effectively.

Anecdotal evidence from solar panel users supports this stance. For example, many users resort to professional cleaning services every few years. Nearly all these professionals avoid using soap-based cleaners and opt for deionized water instead.

Moreover, some find it effective to rinse their panels with a soft water line. Seasonal factors like Santa Ana wind season or fire incidents can affect the frequency of the cleaning. Impact from weather changes, dust, and ash build-up means you sometimes may need to clean your panels as often as every week.

The use of a De-Ionized (DI) system is a common method favored by panel owners. It typically includes a fibreglass extension pole and a brush, which can be an effective solution.

Every aspect of a solar panel, from the construction materials to the cleaning methods, aims to optimize efficiency and prolong service life. As such, it might be wise to stick with the manufacturer-recommended cleaning methods, bypassing soap-based cleaners such as Windex for alternatives like deionized water.

Paying heed to these effective cleaning methods sets the stage for solar panels to perform at peak efficiency. It’s not just about cleanliness, it’s about getting the most out of your investment in solar power.

Pros and Cons of Cleaning Solar Panels with Windex

There’s a fine balance to consider when we’re talking about cleaning solar panels with Windex. It’s not as clear-cut as you’d like it to be. Even with all its advantages like ease of use and accessibility, there are significant drawbacks to consider.

Sure, Windex is handy, affordable, and easy to use. Its availability in most households makes it a tempting choice for a quick clean-up. Swipe those panels clean and they’re back to power production at full throttle. Or are they? Here’s where you need to slow down and consider the repercussions.

Solar panel manufacturers consistently warn against using soap-based cleaning agents like Windex. Why? They’ve got a good reason. Soap-based cleaners tend to leave unholy streaks on the panels, not your everyday, visible streaks, but those annoying ones that mess with your panels’ efficiency. These streaks reflect sunlight away, bearing a direct impact on the power your panels can produce. Truth is, clean panels are efficient panels.

So, alternating your cleaning methods could save your solar panels’ productive life. Your best bet often could be a De-Ionized (DI) water system with a rinse. No soap, no streaks, just a clean, sunlight-absorbing surface. Some solar panel owners have turned this into a system, even hiring professionals that clean both windows and solar panels using deionized water.

MethodProsCons
WindexEasy to use, affordable, commonly availableLeaves streaks, reduces efficiency
DI Water SystemAvoids streaks, maintains efficiencyPossibly more effort, or higher cost

But let’s not forget about the seasons. If you’re surrounded by the Santa Ana winds whipping up fires and dropping ash all summer, you’re likely cleaning much more frequently. This could make a DI water system more attractive, justifying the higher cost with increased efficiency.

Using Other Types of Liquid Cleaners on Solar Systems

We’re going in-depth about other liquid cleaners you might be considering for your solar panels. Let’s explore their effectiveness, precautions, and how they stack up against streaky culprits like Windex!

What is the Best Glass Cleaner for Solar Panels?

While glass cleaners like Windex are often thought of first, they’re not necessarily the best option for solar panels. Leave the Windex for the windows. For panels, you want something that’s not abrasive, doesn’t leave a residue, and is gentle on the material. Strangely enough, one of the top recommendations is windshield washer fluid. It’s designed to handle bird droppings – a familiar foe for solar panels – and other stubborn grime without damaging the surface or leaving streaks.

What is the Best Liquid to Clean Solar Panels with?

The best advice? Keep it simple with water and mild, biodegradable soap. The trick is in the technique. Avoid hard-bristle brushes and high-pressure hoses. Show patience using soft-bristle brushes and plastic blade squeegees attached to a long pole. This approach removes the loose dirt and grime without the risk of scratching or causing damage to the panels. And stick to cleaning panels during cooler parts of the day to prevent sudden temperature changes that can stress them.

Is Vinegar Good to Clean Solar Panels?

Powered predominantly by user recommendations, a mixture of vinegar and water has become a popular homemade solution for cleaning solar panels. Vinegar is an eco-friendly option, but do note that like all cleaners, it must be thoroughly rinsed off to avoid any residue which could affect panel performance.

Can I Use Dawn Soap to Clean My Solar Panels?

If you’re in the soap aisle, Dawn soap could serve you well as a solar panel cleaner. Not only is it effective – gentle enough to clean yet powerful against grime – but it’s also known for its biodegradability. Once again, proper and complete rinsing is important to ensure no soap residues remain that could hinder your solar power performance.

For a cleaning regimen that balances effectiveness, gentleness, and eco-friendliness, a simple combo of water and mild soap, possibly Dawn, checks all the boxes.
