Your Best Guide on Cleaning Solar Panels in Chicago

Solar panel service worker is cleaning a solar panel

Chicago is also known as Windy City since our city is naturally kind of breezy. And when it breezes, there is dust. Over time, it accumulates on panels and lowers system efficiency. Dust acts like a tiny blanket on the panel’s surface, reducing the sunlight that reaches the solar cells beneath, hindering their ability to convert light into electricity.

Dust often accumulates unevenly, creating shaded areas on the panel. These shaded areas become less productive and may not generate electricity at the expected level.

Whether you’re a business owner, property manager, or homeowner, you should acknowledge the importance of cleaning solar panels so they can effectively convert sunlight into electricity, living up to your expectations.

At the same time, when cleaning solar panels on the roof and other sites, it’s crucial to rely on professionals so your panels are properly maintained and work as efficiently as possible, maximizing electricity generation.

Firstly, check the battery. If it has the Power switch on the main switchboard, turn it into the Off position. If you have a separate inverter, look for a switch called a solar AC isolator. Never touch electrical components while the system is on.

Common Mistakes When Cleaning Solar Panels in Chicago

First of all, we’d recommend using a mild cleaning solution for solar panels, as harsh components irreversibly damage the coating of photovoltaic cells.Work only during moderately warm weather, from 55°F to 70°F. Avoid cleaning on hot days as the panels can be very hot and increase the risk of burns.

Don’t use pressure washing while cleaning your solarpanels, as you may not accurately estimate the perfect amount of water pressure. Incorrect washing can irreversibly damage the panels.

We also don’t recommend cleaning solar panels with hard water, as it hasa high concentration of dissolved minerals. Usually, it’s calcium and magnesium ions that stay on the panel. These deposits can act like a film, reducing sunlight that reaches the solar cells and hindering their ability to convert light into electricity.

Self-Cleaning Solar Panelsfor Lazy Homeowners

There’s a bit of a nuance with “self-cleaning” solar panels. Their hydrophobic or hydrophilic coating is water-repellent for dust but attractive to water, creating a thin water layer that washes away the dust.

Some coatings additionally use titanium oxide, which activates with UV light. Once the panels catch the Sun’s rays, they develop a mild chemical reaction that loosens dirt and promotes easier rinsing with water.

Is Cleaning Solar Panels on the Roof More Dangerous?

Cleaning solar panels on the roofis generally more dangerous than cleaning them in the field. Therefore, we recommend hiring certified cleaners to clean your panels safely and prolong their lifespan.
