While Hawaii residents have come to rely on photovoltaic (PV) systems and solar power for cost-effective and sustainable energy, homeowners are usually unaware that their solar panels require regular cleaning in order to maintain optimal performance.

And, because solar panels are usually situated atop one’s roof, the “out of sight, out of mind” mentality sets in as dirt, salt air, bird droppings and even road grime can block the sun’s rays from reaching the power-generating system, which can cause up to a 25 percent drop in productivity. Clean Solar Panels Hawaii was launched in 2016 when owner Dorian Takahashi realized how filthy his own solar panels were getting and sought out a solution.


“We offer cleaning of solar panels using a special non-abrasive brush and ultra-pure water,” Takahashi explained. “It’s critical to remember the importance of maintaining your system. You want to be sure to take care of the investment, which in turn pays you back.”

Takahashi noted that Hawaii’s climate produces water that is normally laden with minerals. Using a car windshield as a comparison to solar panels, the areas not covered by swiping windshield wipers over time develop a layer of hard water buildup caused by mineral deposits. Clean Solar Panels uses a special water filtration system to remove minerals from the water used in cleaning dirty solar panels, much like a car being detailed.

“Just like washing a car, you want to make sure that you keep a PV system clean to provide optimal efficiency,” Takahashi said. “The cost of maintaining your system is only a fraction of what you’re missing out on when solar panels are left dirty. The cost of regular maintenance is usually covered with increased energy production.”


Clean Solar Panels offers cleaning services starting at just $10 per panel — an excellent value considering the enhanced performance and cost savings that result in the long run. For more information, log on to cleansolarpanelshawaii.com, and call 454-7565 for a free estimate.
