Solar Panel Washing FAQs
Do solar panels need washing?
Solar panels benefit from routine washing to clear efficiency-reducing buildup and contaminants. In Honolulu‘s unique conditions, panels collect volcanic ash and other debris that can reduce efficiency by as much as 20-25%. Research indicates that clean solar panels produce markedly better performance than dirty ones. Most manufacturers advise maintaining your array at least every 3-6 months in locations like Hawaii to ensure optimal performance.
What is the best method of cleaning solar panels?
The best method for cleaning solar panels involves ultra-pure filtered water and soft cleaning tools to prevent damage. Harsh cleaning chemicals should be kept away from panels as they can deteriorate the panel’s finish and possibly nullify manufacturer guarantees. Soft-bristle brushes attached to extension poles allow for safe cleaning without endangering yourself. Our specialized equipment uses pure water filtration systems that prevents water spotting while effectively removing stubborn buildup.
How often should solar PV panels be cleaned?
Here in Honolulu, we recommend cleaning your solar PV panels every 3-4 months to ensure peak performance. Arrays positioned adjacent to coastal areas may benefit from additional maintenance due to marine layer deposits. During vog events, extra cleanings may be required to remove ash deposits. Numerous system owners opt for a routine service agreement that guarantees maximum output year-round.
Does rain clean solar panels?
While rain offers some cleaning benefit, it simply isn’t adequate to effectively clear solar panels, especially in Hawaii. Rain can help with rinsing surface dirt, but it doesn’t adequately clean stubborn contaminants that impact panel performance. Natural rainfall offers limited cleaning and often leaves behind water spots when it dries. In Oahu specifically, rain often brings atmospheric debris like volcanic ash that can eventually create a residue on your panels. Proper maintenance removes stubborn buildup that rain leaves behind, including salt deposits and environmental coatings. Scheduled maintenance is still required to preserve peak output of your panel system.
What happens if solar panels are not cleaned?
Failing to clean your solar panels causes accumulated buildup that reduces light penetration and diminishes power output. In Oahu specifically, unmaintained panels can see a decrease of as much as 20-25% of their efficiency due to volcanic ash and various residues. With prolonged neglect, the higher temperatures caused by contaminant layers can increase wear on materials, potentially shortening system lifespan of your panel system. Regular professional cleaning eliminates these negative effects and guarantees your solar system continues to performing optimally for many years to come.
