Solar Panel Cleaning & System Check

Think of it as an annual cleaning & check-up for your solar system!

Panel Cleaning & System Check

An annual cleaning & check-up for your energy system.

When you book a RevoluSun panel cleaning, you don’t just get a sparkling system—you get a certified PV technician performing a full health check on your solar + storage setup. While other companies might just wash your panels, our technicians dig deeper to make sure everything is running at peak performance.

We:
• Inspect all electrical equipment for safety and wear.
• Run inverter diagnostics to pinpoint and resolve errors
• Verify system network communication
• Check battery health and performance
• Ensure firmware is updated to the latest version
• Simulate a power outage to confirm your backup system works when you need it most

This isn’t a surface-level service. It’s a proactive inspection by the same experts who install and service solar every day—because your system deserves more than a rinse, it deserves real care.

Before & After

Solar Panel Cleaning Before-and-After Production Results

Cleaning your solar panels can make all the difference in the world in power output before and after cleaning. Many times, visual inspections give an idea of how much dirt has built up, but the real proof is in the numbers.

Before Cleaning: The voltage of the solar panel may read lower because the sun is “blocked by built-up debris.”

After Cleaning: Voltage readings normally go up, showing immediate changes following the removal of debris.

How Often Should I Clean My Solar Panels in Honolulu?

We suggest an annual cleaning but some people like to clean twice a year to keep their panels at peak production. The frequency of solar panel cleaning in Hawaii really depends on various factors, from the tilt of your solar panels, to environmental factors including proximity to the ocean, major roads or highways, proximity to agricultural farms and new housing developments that increase dust levels, and organic debris.

Solar Panel Cleaning FAQ

Clean solar panels produce more power. In Hawaii, panels are often exposed to salt air, red dirt, dust, and bird droppings — all of which can reduce efficiency. Dirty panels block sunlight from reaching your system’s solar cells, which means less energy production and higher electric bills. Regular solar panel cleaning in Hawaii is one of the best ways to protect your investment and keep your system running efficiently.

Our professional solar panel maintenance service covers both cleaning and a detailed rooftop inspection:

Safe, effective solar panel washing
Visual inspection of racking, mounts, wiring, and roof attachments
Securing loose wires and hardware
Replacing worn zip ties or brackets
Before-and-after photos of your system
A summary report of our findings and any concerns
If we find issues like worn seals, cracked piping, or solar hot water component damage, we’ll notify you and offer repair options. Minor fixes are typically addressed on the spot.

We recommend cleaning your solar panels at least once a year in Hawaii. Homes near the ocean, busy roads, or dusty areas like Kapolei, Makakilo, or Ewa may need more frequent cleaning to maintain performance and qualify for warranties. Also, homes that get frequent rainfall tend to have major build up that affects rows of solar cells.

Regular solar panel maintenance helps ensure your system lasts longer and delivers maximum output year-round.

If we find anything serious — such as exposed wires, damaged racking, or faulty components — you’ll be notified immediately. We’ll walk you through your options and help coordinate repairs. Keeping your system safe and performing is always our top priority.

How do I know if my solar panels need to be cleaned?
If you haven’t had a cleaning or inspection in over a year — or ever — you’re likely overdue. Salt buildup, airborne dirt, and even vog can all accumulate and reduce your system’s output.

Think of solar panel cleaning like a tune-up for your car. You may not notice performance drops immediately, but your system is working harder (and producing less) when it’s dirty.

Not always. While big messes like bird droppings are easy to spot, most dirt builds up gradually and evenly — making it hard to see. It’s like your car windshield after a week of driving: it may look fine until you wipe it down and realize how much was blocking your view.

RevoluSun offers professional residential solar panel cleaning across Oahu. For commercial systems, we service Oahu, Maui, Kauai, and the Big Island. Whether you have a PV system, solar hot water, or energy storage — we’ll help you keep it clean, safe, and operating at peak performance.

Signs You Need Your Solar Panels Cleaned

If your solar system’s output is significantly lower than usual, it could be a result of accumulated dirt, dust, or debris. Monitoring your energy production through your solar system’s app or inverter can help identify any sudden drops that indicate soiling.

A quick visual inspection can reveal if your panels are covered in dust, bird droppings, salt residue, or organic matter. Even a thin layer of dirt can reduce sunlight penetration, affecting energy output.

Frequent rain showers in Hawaii can leave behind mineral deposits or streaks, especially if the rainwater mixes with salt or dust already present on the panels.

Certain times of the year, such as spring or summer, may bring increased pollen, foliage debris, or volcanic ash in specific areas. If you notice these seasonal elements accumulating on your panels, it’s time for a cleaning.

Homes near the coast often experience salt spray buildup, while those near vegetation may see more bird droppings and organic debris. If you’re located in one of these areas, cleaning is likely needed more frequently.

If some panels in your array are performing differently than others, it could indicate localized soiling that needs to be addressed.

Cleaning your panels promptly when these signs appear can restore energy efficiency and protect your investment.

 

 

Oahu Specific Environmental Factors Leading to Buildup on Solar Panels

Proximity to the ocean exposes solar panels to salt-laden air, which can lead to salt deposits accumulating on the surface. This layer of salt not only reduces sunlight absorption but can also cause long-term corrosion if left unchecked.

Tropical trade winds often carry fine dust and dirt particles from surrounding areas. These particles settle on solar panels, creating a film that diminishes their ability to capture sunlight.

Hawaii’s lush vegetation, including nearby trees and flowering plants, contributes to the buildup of pollen, leaves, and bird droppings on solar panels. Organic debris can create sticky, hard-to-remove layers that block sunlight.

In areas close to volcanic activity, such as the Big Island, ash particles can settle on solar panels. This type of soiling is especially abrasive and requires specialized cleaning to avoid scratching the panel surfaces.

While rain is a natural cleaner for solar panels, frequent showers in Hawaii can leave behind mineral deposits and water stains, particularly if the rainwater mixes with existing dust or salt deposits.
