When can I schedule an appointment?
Call us at (808) 427-3197 or use contact us by email.
How do I pay my bill?
Check or any credit card is fine.
What products do you use to clean the solar panels?
We use de-ionized water through a water-fed brush. De-ionized water is what you get when you run our ground water (tap) thru special resin beads, which remove all of the TDS (total dissolved solids, such as calcium, magnesium, silica) from the water. This results in water that leaves no hard water marks or any marks if dirt is put into solution and rinsed well. We use a pole with a white pad if there’s additional residue not easily cleaned with water.
How often do you suggest the solar panels be cleaned?
Manufacturers suggest an annual cleaning. Some warranties require an annual cleaning.
Do I need to be home for the solar panel cleaning?
No.
Do I need to turn my panels off for the solar panel cleaning?
No.
Why should I have my solar panels cleaned?
Solar panels work by harnessing the sun’s energy (photons). The more sunlight (photons) that pass thru the glass on the solar panel the more electricity the panel can produce. Dirt, kaka, and even salt buildup can impact a solar panel efficiency resulting in a lower production of electricity.
Will the cleaning my solar panels void my warranty?
No.
Can I hose my solar panels down?
Using a hose to clean panels with ground water (tap) is not recommended because of buildup of hard water marks. If you don’t have access to purified water of some sorts, I would recommend cleaning while it rains. Be safe.
