I would highly recommend Hawaii Solar & Window Cleaning Company. if you're looking for value, quality & availability in getting your solar panels hand cleaned. For optimal output, panels should be cleaned at least twice a year.

"Great job! The work was very thorough and the service friendly and professional I highly recommend this company. I will use them again."
Katherine Kean: Keaau, HI
"I requested an estimate and within a few days Mike was able to come over and do the work. My panels are about 12 years old and never professionally cleaned. The top rows were nearly solid brown. Mike did a fantastic job. The panels are as shiny as new, and producing at least double the output as I had been getting recently! I expect my next electric bill will be much lower than last month. I can highly recommend Hawaii Solar and Window Cleaning!"

Why is insurance important? Are you insured?
Why is insurance important? If damage occurred to your home by a contractor, or an injury on your property you could easily be held responsible. Always ask for proof of insurance.

Commercial Projects usually will require an on-site estimate.
Do you offer any discounts?
Yes! We offer a 10% "Bundle Discount" if you have your solar panels & windows are cleaned on the same day.
What method do you use to clean solar panels?
We use deionized water and a soft nylon bristled brush to clean solar panels. Never use a pressure washer to clean your solar panels!
For commercial jobs we use a water-powered rotary brush which uses a power washer to propel the brush.
Does rain clean solar panels?
Rain fall will provide a rinse of loose dirt or dust. However, it will not remove mold and mildew that is common on the Big Island.
How often should I have my solar panels cleaned?
It is recommended to be clean solar panel twice a year. It also depends on your budget, the micro-climate of your home, the pitch of your roof and other factors like birds, salt spray, volcanic ash, dirt roads, trees, and damage from pressure washing.
Some of our customers have their panels cleaned 3x/yr. while others can go as long as 2 years between cleanings.
Do I need to be home for my solar panel cleaning appointment?
No, you don't have to be home. We will keep you updated by SMS/Text messages and photos.
Is there anything I need to do to prepare for my solar panel cleaning appointment?
If you have a water catchment tank then you can divert the water to your tank before we arrive. We can do this for you but cannot be held responsible for damages. Downspouts tend to get brittle over time from sun exposure.
Is a there a difference between a professional window cleaning and a house cleaning service?
The short answer is emphatically “yes!”. Mike is a window cleaning specialist and is dedicated in his profession. Mike is trusted to clean the windows for the Hilo International Airport Traffic Control Tower, multi-million dollar homes and his favorite... cleaning windows for residential customers on the Big Island!

Is there anything I need to do to prepare for my window cleaning appointment?
If you are having your exterior windows and screens cleaned (no interior window cleaning) then we recommend removing the screens and placing them outside next to the window it came from. Most modern screens are removed from the inside. We will replace the screens from the outside. If you have older style screens that are removed from the outside then we will remove them.
If you are having your interior windows cleaned then we recommended moving furniture about 2-3 ft. from the windows. We can move heavier items for you. Please also put away items that are fragile like vases that can be knocked over.
What if it rains after my windows are cleaned?
Professionally cleaned windows really shouldn’t spot if it rains. Dirt makes your windows dirty, not rain.
