Clean Solar Panels Hawaii was founded in 2016 by Dorian Takahashi. Dorian decided to start the company when he couldn't find anyone in Hawaii to properly clean and maintain his own solar panels. With a background in solar sales and installation and marketing, he recognized the need in the market and decided to begin researching solar panel cleaning. 6 months of contacting different companies and doing research led to the proper technique and equipment of cleaning solar panels.


The company started with a small capital investment from Dorian’s parents, a used Ford F150 truck, and a lot of hardwork and door knocking. Within the first 6 months the company cleaned roughly 160 solar panels and in the second year they cleaned roughly 2000 solar panels. In 2020, we now have 3 vehicles, 8 employees, have cleaned over 100,000 solar panels, and have serviced on all the major Hawaiian islands. Services have also expanded from residential cleanings to include commercial cleanings and became the exclusive distributor and installation company for Diamond Fusion solar panel coating in the state of Hawaii.


Dorian Takahashiattributes a lot of his success to his background in marketing, focus on customer service, and attention to detail.





With the recent heat, homeowners’ electricity usage is steadily increasing. Homeowners are realizing the need to clean and maintain their solar panel system. Cleaning solar panels the wrong way can void warranties and can be extremely dangerous. Hiring a professional is highly recommended. Whether you hire a professional or do it yourself, there are 5 things you should consider when cleaning solar panels.



1. Harsh chemicals should never be used as it can damage solar panels. Chemicals that are too harsh and will remove the anti-reflective coating on your panels. This coating increases the capture of light and helps the solar panels achieve at its peak performance.


2. Deionized and/or RO filtered water is key to cleaning. Using normal hose water will leave calcium and other mineral deposits that are contained in hard water, will be left on the glass. For example, if you spray your car’s windshield with a hose and let it dry, it will be filled with hard water spots and will be harder to see through. Filtered water should be used to ensure you get the most amount of sun to the panels.

3. Using the right equipment is key. Brushes that are too abrasive will damage panels. Most professionals will use a specially designed, non-abrasive brush on a long carbon fiber pole to avert from stepping on panels. It is not recommended to use aluminum poles or any other metal that is highly conductive when working near electricity.


4. Never pressure wash! It is never recommended to use high pressure on solar panels. High pressure can damage the panels’ reflective coating and even break the glass. Also, if the pressure washer is not using filtered water, hard water spots will remain on the panels.






5. Inspect your system. Many times, hidden fire hazards are created by leaves and animal nesting. Other common occurrences are malfunctioning or broken equipment. Most solar panel cleaning companies will offer an inspection of the solar system. Many homeowners lack the knowledge and specialized equipment to inspect the system themselves.
