According to the SEIA, residential solar installations across the USA reached record levels for the sixth consecutive year in 2022. That’s thanks to increased federal incentives and growing awareness of environmental concerns due to carbon emissions.
Not only will a solar installation help you save the planet, but it can also help you slash your electricity bills if you know how to maximize its potential. Cleaning your solar panels regularly is one way to ensure they work at their best.
It’s easy to go wrong when you attempt this simple task, and mistakes with solar system cleaning can cost you thousands of dollars in lost savings.
Avoid these blunders to ensure you get the best bang for your buck when you install solar panels.
Slacking on Solar Panel Cleaning
Most solar companies recommend you clean your residential solar system once a year, but it’s best to inspect it at least once every three months.
The longer you leave dust and dirt on your solar panels, the harder it will be to clean them. So, if you notice your panels looking a little dingy, clean them as soon as possible.
Dirt and grime decrease the efficiency of your solar panels by blocking the sun’s rays. Yet, over-cleaning them can lead to scratches and permanent damage.
It’s important to set up a solar system cleaning routine and only use approved methods for cleaning your solar panels.
Mistakes With Solar System Cleaning Tools
Always keep a stock of solar panel cleaning supplies so you can attend to your solar panels when necessary.
Avoid using abrasive materials like steel wool to clean your panels; these materials can damage them. Rather, use a soft cloth, soft bristle brush, or sponge and a mild soap solution made specifically for solar panels.
A vacuum cleaner or window squeegee also works well for loosening dirt without causing any damage.
Before you start cleaning your solar panels, take note of any contaminants that might be stuck to their surfaces. Plain water is rarely enough to remove things like tree sap or bird droppings.
Never use chlorine bleach or acid to clean your solar panels. Vinegar is a better choice for removing stubborn dirt.
Many homeowners use regular window cleaning solutions to clean their solar panels. These solutions contain chemicals that can damage your solar panels’ protective coating.
Using the incorrect supplies to clean your solar panels can cause streaking. This will reduce their effectiveness.
Overcleaning solar panels is another common mistake that many homeowners make. Using too much cleaning product or mixing it incorrectly may also result in streaking or leave a visible residue on your PV panels.
Always follow the manufacturer’s instructions to the letter when cleaning your solar panels.
Cleaning Solar Panels in Direct Sunlight
Direct sunlight will cause cleaning materials to dry on your solar panels and may result in streaking.
Always clean your PV panels during the coolest times of the day, such as early in the morning or late in the afternoon. This will give you enough time to rinse your panels properly before the cleaning solution dries.
Misjudging the Necessary Water Pressure
Rinse off all soap residue after you’ve cleaned your solar panels. Otherwise, dirt will stick to it and collect between the tiles of your solar panels.
Distilled water is best for cleaning your PV panels, as tap water contains minerals that can build up on their surfaces. Any residue left behind can cause overheating, reduced efficiency, and solar panel failure.
For this reason, you should use plenty of water when rinsing your PV panels, but also avoid using too much, or you will eventually reduce the solar panels’ ability to absorb sunlight.
If you don’t have distilled water, you can use clean tap water you’ve left out for at least 24 hours to allow the chlorine to dissipate.
When you rinse your solar panels, use a pressure washer. This gives you control over how much force you apply during the rinsing process.
You should apply only enough pressure to clean off the dirt, so set the nozzle at its lowest setting. This is usually sufficient pressure to rinse the panels effectively without damaging them.
Not Checking for Solar Panel Damage First
Regular solar panel inspections are vital for ensuring your solar system meets your expectations. Before you clean your solar panels, check for faulty wiring, wear and tear, corrosion, and broken parts.
If you notice anything unusual, contact a solar repair technician immediately. Faulty solar panels are a fire hazard, and you could cause serious damage if you clean a solar panel with a cracked veneer or loose wiring.
Disregarding Safety When Cleaning Solar Panels
Water and electricity can be a recipe for disaster.
Never reach into pools of standing water near electrical components. You might experience a nasty shock or even get electrocuted.
It’s best to wear approved safety gear when cleaning your solar panels. Insulated rubber gloves and rubber-soled shoes are vital for ensuring you’re safe during this task.
Cleaning your solar panels also involves further risks associated with working at height. Always wear a safety harness when you climb onto the roof of your home.
Work slowly and methodically, and never become careless about safety around solar panels.
By far the safest way to ensure effective, safe solar panel cleaning is to get in touch with an experienced solar company to assist you with this routine task.
