What Our Solar Panel
Cleaning Services Include?

Among the various causes of reduced solar panel efficiency, dirt and buildup are one of the main culprits. Get them cleaned now and start saving on your energy bills again with our professional solar panel cleaning services.

Professional Panel Washing with Pure Water

We use purified or deionized water along with soft brushes to gently but thoroughly wash each panel. This method removes dust, pollen, bird droppings, salt residue, and other grime without scratching the glass or leaving streaks, ensuring maximum sunlight absorption. We use Diluted Sodium Hypochlorite and Biodegradable Surfactants for tough build-up like mildew or sticky residue.

Visual Inspection for Damage or Wear

During every cleaning, our team performs a basic visual inspection to check for cracks, discoloration, loose wiring, or visible hotspots. We notify clients if we spot anything that might affect their system’s performance or safety.

Performance Check & Efficiency Tips

After the cleaning, we offer feedback on your system’s condition and simple tips to help you maintain your solar performance between professional visits. This could include ideal cleaning frequency, tilt-angle adjustments, or nearby shade-related suggestions.

Sudden Increase in Your Electricity Bill

Noticed your electric bill rising unexpectedly even though your habits haven’t changed? It could be dirty panels reducing your system’s efficiency and causing you to draw more power from the grid.

If your panels look dusty, stained, or discolored from the ground, they’re likely covered in bird droppings, salt spray, mildew, or general grime—blocking sunlight and reducing power generation.

If it’s been 12+ months since your last solar panel cleaning, or you’ve never cleaned them at all. Even panels that “look” clean can lose up to 30% of efficiency.

In tropical or rainy areas like Hawaii, excess moisture promotes mildew growth on solar panels. Regular cleaning helps prevent buildup and long-term damage to the panel surface.

Flat or low-angle panels don’t shed water and debris as easily. This makes them more likely to accumulate standing water, mildew, and dust, all of which interfere with sunlight absorption.

Panels near highways can collect road grime. Coastal homes may suffer from salt deposits. And if you have overhanging trees nearby, pollen and sap are also common culprits. All of these reduce efficiency.

Frequently Asked Questions
About Our Solar Panel Cleaning Services

Why do solar panels need to be cleaned?

After a residential solar installation, cleaning is important because dust, dirt, bird droppings, and pollution can block sunlight from reaching the photovoltaic cells. Regular cleaning keeps panels efficient, ensures maximum energy output, and extends the life of your solar system.

It’s recommended to clean your solar panels at least twice a year. However, in dusty areas or places with frequent bird activity or pollen, quarterly cleaning may be more effective. If you don’t want your solar panel cleaned after some time, you’ll see a heavy drop in energy efficiency of up to 30%.

While it’s possible, cleaning them yourself can be risky, including falls and electrical hazards. Panels are often hard to access, and using the wrong tools or detergents may damage them. Professional cleaning ensures safety and the right methods. We use a custom, eco-friendly cleaning solution made for each property. It usually includes water, safe surfactants, and a small amount of sodium hypochlorite, the same stuff used in pool cleaning and even drinking water treatment. It’s great for removing bacteria, algae, and dirt without harming your solar panels or the environment.

In Hawaii, solar panel cleaning costs between $150- $330, and the per-panel cost is between $8-$25. Pricing depends on the size of your system, panel accessibility, and location. We provide free quotes with no hidden fees and affordable pricing.

  2. Extension Poles with Water-Fed Brushes (For safe &streak-free cleaning)
  3. Purified/Deionized Water (Leaves no spots or mineral buildup)

  5. Low-Concentration Sodium Hypochlorite (remove algae & mold)
  6. Glass-Safe Cleaning Agents (for stubborn buildup)

We don’t provide solar panel cleaning services during heavy rain, strong winds, thunderstorms, or extreme heat. These conditions can create safety risks for our team and reduce cleaning effectiveness. For best results and safety, we schedule cleanings during mild, dry weather when visibility is clear and surfaces are safe to walk on.

Cleaning solar panels typically takes between 30 minutes to 4 hours, depending on the number of panels, their condition, and how easy they are to access. Smaller residential systems are usually cleaned quickly, while larger or hard-to-reach setups may take more time to ensure every panel is properly cleaned and inspected.

We offer solar panel cleaning services across Hawaii, including Hilo, Kailua, Kalapana, Keaau, Kona, Kurtistown, Milolii, Naalehu, Pahoa, and Waikoloa. Contact us to check availability in your area.

Yes, it’s highly recommended to shut off your solar system before cleaning. This ensures the safety of both the cleaning technicians and your equipment. Solar panels generate electricity as long as they’re exposed to sunlight, even if it’s cloudy. Cleaning while the system is live can pose an electrical shock hazard, especially when water and cleaning tools are involved. If you’re unsure how to turn off your system safely, our team can guide you through the process or handle it during the service.

Yes, we service commercial solar panel systems of all sizes. Our team can handle large-scale arrays on rooftops, parking canopies, and solar farms.
