Solar power has been increasingly in popularity exponentially over the past few years. Today, not only is solar energy cost-effective, it is at the forefront of the green energy revolution, actively decreasing our global carbon footprint, and helping to offset some of the damage caused by non-renewable energy sources. When maintained properly, solar panels can produce high amounts of electricity without damaging the environment, whilst saving you money year-in, year-out, for many years to come.

Solar Panels require little maintenance aside from regular cleaning in order to work at maximum efficiency. Rain water alone is insufficient in cleaning, and so a versatile scrubbing brush tool is required. We review the best solar panel cleaning pools available today, with feature breakdowns, pros, cons, and reviews.

Solar panels require little maintenance, and can last many years without requiring replacement parts. However, one thing all solar panels do require, in order to operate at maximum efficiency, is a regular cleaning. A dirty solar panel may be producing 15-25% less electricity than a clean one. In other words, the cleaner your solar panels are, the more efficient they will be, the more electricity you’ll produce, and the more money you’ll save.

When looking for cleaning tools and supplies to keep your solar panels sparkling, you’ll be glad to learn that there are myriad products available to you. In this list, we discuss our top five choices for solar panel cleaning tools, examining their features, pros, and cons. It’s our hope that by the end of this article you’ll feel ready to make an informed decision and an educated purchase. Let’s dive in.

How Do Solar Panel Cleaning Tools Work?

Whilst these products are fairly straight-forward, it’s worth taking a brief look at the inner workings of the brushes and flow-through panel cleaners reviewed in this article, so that you are fully aware of what you’re looking at.

Generally speaking, solar panel cleaning tools consist of a long, telescoping (extendable and retractable) pole with a brush at one end and an easy-grip handle at the other. Some of these tools can be connected to a hose or outdoor faucet so that you can pump water through the pole and out at the brush end to enhance the tools’ cleaning potential.

Whilst small variations do exist from product to product, there are some standard parts and processes which we’ll now discuss.

Brush Head

The brush end of solar panel cleaning tools holds a soft-bristled brush, sometimes with two layers of brushes (one for lifting dirt, one for brushing it away). The bristles are designed to be soft enough that they’re not liable to scratch the surface of your expensive solar panels (obviously an important feature). In short, the brush head works as does any domestic brush.

Telescoping Pole

The pole onto which the brush head is attached is telescoping, meaning that it can be extended up to a maximum reach, clipped into place there (so that it is secure), and then retracted for storage or for more accessible cleans. The reach range of solar panel cleaning products varies greatly, from just 4-6ft, to 6.5-20ft. The poles are made of a wide range of materials, all lightweight, with the very best being made from aerospace-quality aluminium (strong and light).

Handle

The handle of solar panel cleaning brushes tends to be made of material which makes it easy to grip, usually some sort of foam or plastic.

Hose Attachment/Water Functionality

Whilst not included in all solar panel cleaning products, the best tend to be compatible with outdoor faucets and hoses in one way or another. Hoses and/or faucets may usually be screwed onto the handle-end of the solar panel cleaning tool, from which they send water up the telescoping pole to spray out of holes in the brush end. This water functionality enhances the cleaning experience by ensuring that dirt is not only lifted and brushed away, but washed away with clean, fresh water, too. Some solar panel cleaning tools even have ON/OFF buttons to regulate the flow of water as and when needed.

How to Choose a Solar Panel Cleaning Tool

Now that you know what components go into the construction of solar panel cleaning brushes, let’s answer a few questions you need to consider before purchasing one.

Location of Solar Panels

The accessibility of your panels will be the biggest factor affecting your decision to buy a panel cleaning kit. As we stated earlier, cleaning tools for solar panels tend to have telescoping poles of varying lengths. It’s the length of the pole which you need to consider. If your panels are mounted on the roof of your house, then it’s very likely you’re going to need a tool which can extend up to 20 feet. However, if your panels are ground mounted, say in your garden, then you could of course get away with a cleaning brush which has a much shorter extension range.

Cleaning Requirements

Most of the tools on this list are compatible with hoses and outdoor faucets, but that’s not the case for every item reviewed here. Before you buy, it’s worth considering whether you want the ability to wash your panels with water directly through the brush or not. If your panels are roof-mounted, water-compatibility is probably a good option, since you can’t always rely on rain water, and it would be hard to get up there with a bucket of water yourself. However, if the panels are more easily accessible, then you may feel you only need a dry brush.

Budget

As always, budget is a necessary consideration for most of us. Thankfully, these tools tend to be pretty affordable, especially in relation to the panels. Most come in at under $50, with still others as cheap as $25-30. The difference tends to come from functionality and materials used, and whilst not always true, in this case a little more cash does seem to buy you a more quality product.

Solar Panel Cleaning Tools Buyer’s Guide

What are the features to look out for?

Hose-Compatibility

Does the cleaning tool come with a hose, or even the ability to be attached to an existing hose or outdoor faucet? Such cleaning tools make the scrubbing and washing of hard-to-reach and roof-mounted solar panels much, much easier, whilst those without require either a dry-clean or manually retracting and dipping the brush head time after time until the panels are clean.

Cleaning-Product Compatibility

Is it possible to use cleaning products directly through the brush? Some brushes can be preloaded with your preferred glass cleaner or cleaning product, which can then be sprayed from the head, whilst others are only compatible with cold water, and still others are dry brushes only.

Materials (Bristles vs Silicon)

What materials is the cleaning kit you’re looking at made of? Is the pole made of flimsy stuff, or aerospace-grade aluminum? Is the handle easy-grip? Has the brush got soft bristles (ideal for lifting layers of dirt) or a silicon mop head (only good for light cleaning)? Depending on how often you intend to clean your panels, and how dirty they tend to get, these are important considerations to make.

Warranty

A product with a warranty (whether 1-year or lifetime) is without doubt more trustworthy than one without. If a manufacturer isn’t offering their customers a warranty, chances are the product isn’t going to last very long before breaking or malfunctioning.

Final Verdict

Solar panels don’t require much maintenance, but keeping them clean is essential to their performance. A clean panel can be up to 25% more efficient than a dirty one. Whilst some solar panel owners opt to wash them down with just a hose, this is insufficient and leaves lots of tough dirt and grime on the panels. Taking into consideration the potential reach, functionality, compatibility and price of all the solar panel cleaning kits we’ve reviewed here, it seems clear to us that the very best product available on the market has to be the EQUIPMAXX Water Fed Pole Kit. With a pole extending up to 20-ft, soft yet hardy bristles, and a water-feeder which comes with its own lightweight, flexible hose, this is your best bet if you want to keep those roof-mounted solar panels clean and optimised for performance.

FAQs

Q: Doesn’t rain clean my solar panels enough already?

A: Unfortunately, no. Rain can help to clear off a bulk of heavy particulates but does not effectively rid the glass of smaller dirt and grime. Keep in mind that sap, smog, pollen, bird droppings, and other things that can greatly decrease the efficiency of your panels accumulate quickly, and require more regular, deeper cleaning than you can depend upon from rain alone.

Q: Is it okay to use cleaning chemicals on my solar panels?

A: To some extent, yes. Cleaners can help to rid the glass of sticky or heavy buildups. Do keep in mind, however, that the wires underneath the panels do not need cleaning and that some cleaners can be corrosive. It is also important to remember that some cleaners can leave a residue. Residue can build up and decrease the efficiency of your panels over time. Check with your manufacturer’s recommendations and restrictions before deciding to use a cleaner, and always thoroughly rinse your panels after cleaning.

Q: Is it important that my cleaning tool hooks up to a water source?

A: This depends upon the accessibility of your panels. If you have a two-story home and your panels are on the roof, for instance, it might be difficult to safely get water and cleaners to the roof without a cleaning kit which has water compatibility/a sprayer head built-in.

Q: How often should I clean my solar panels?

A: A general recommendation is about every three months, however, if you have severe rain, smog, wind, or snow; it might be a better idea to clean them more often, perhaps once a month.
