Solar Panel Cleaning Tips 

Switching to solar panels is a smart move, not just for your wallet but also for the environment. As solar installation costs decrease and energy prices rise, many homes and businesses opt for solar power. With tax incentives available, the future looks bright, with projections suggesting that one in seven U.S. homes will have a solar PV system by 2030.
At Solar Earth Inc., we emphasize two critical factors in solar design: reliability and longevity. Well-maintained solar panel cleaning is crucial to ensure optimal performance and energy cost control for years.

Questions to Consider for Solar Panel Cleaning Needs

When pondering the cleanliness of your solar panels, consider the following questions:

  • Do you live in an area with heavy pollution, smog, or smoke?
  • Are tall trees surrounding your home?
  • What is the pollen count in your area?
  • How often does it rain?

Factors like dirt, dust, pollen, bird droppings, leaves, and other debris can impact solar panel efficiency. Monitoring your energy bills and observing power output changes before and after cleanings can guide you on how often to clean solar panels. Most panels require minimal cleaning, thanks to their slanted installation that allows debris to wash away during rainstorms.

What NOT to Do When Cleaning Solar Panels

Avoid these actions to prevent damage to your solar PV system:

Walking on Panels: Never walk on solar panels as it can scratch or fracture the solar panels, reducing power output.

Using Pressure Washers: Pressure washers can scratch and damage photovoltaic solar panels, potentially causing water to enter the panels.

Efficient Steps for Cleaning Solar Panels

Understanding your solar panel system’s unique characteristics is crucial for proper maintenance. Most solar panel manufacturers provide comprehensive guides that offer valuable insights into their products specific needs and recommended cleaning procedures. Take the time to read and familiarize yourself with the manufacturer’s guide – a document often overlooked but rich in information.

Manufacturers often include detailed instructions on the best cleaning agents, acceptable tools, and frequency of maintenance. Some solar panels may have specific recommendations, such as whether the system should be shut down during cleaning. Consulting this guide can help you tailor your cleaning routine to meet the particular requirements of your solar panels.

Choose the Optimal Time for Cleaning

Solar panels are most effective when they receive direct sunlight. However, cleaning them while they are in direct sunlight can result in watermarks or soap smudges. To avoid this, schedule your cleaning sessions in the morning, evening, or overcast days when the panels are not under direct sunlight.

Cleaning during these times ensures a thorough job without compromising efficiency and minimizes the risk of overheating the panels. By picking the right time, you maximize the benefits of the cleaning process and contribute to the sustained performance of your solar energy system.

Handle with Care – Be Gentle During Cleaning

While solar panels are durable, handling them with care during the cleaning process is essential. Avoid using metal objects, abrasive detergents, or high-pressure washers, as these can cause damage to the system. Instead, opt for a gentle approach using mild dish soap, a soft sponge, or a squeegee.

These gentler cleaning tools and solutions effectively remove dirt and grime without jeopardizing the integrity of the solar panels. By adopting a cautious cleaning strategy, you ensure the longevity of your solar panels and maintain their efficiency over the long term.

How Often Should Solar Panels Be Cleaned

Clean your solar panels at least twice annually, regardless of weather or location. This routine reduces Solar panels that can get hot very quickly when they’re out in the sun. We suggest you clean your solar panels in the morning, early evening, or on a cool, cloudy day to keep two things from happening.

When To Clean Solar Panels?

Solar panels can get hot quickly when they’re out in the sun. We suggest you clean your solar panels in the morning, early evening, or on a cool, cloudy day to keep two things from happening.

For one thing, if it’s hot, the rapid cold water could break the glass. For another, if the water dries too quickly, it could leave behind droplets on the panels. These two things would make the solar system less useful.
