Quick SummaryNanoTech coating is a self-cleaning layer applied after professional cleaning, using anti-reflective, anti-static, photocatalytic, and superhydrophilic properties to resist dust and boost output 2–8% beyond a spotless, uncoated panel. It typically lasts 5 to 10-plus years, backed by a 3-year warranty, and dramatically reduces how often manual cleaning is needed.

Cleaning restores your panels to baseline. Coating goes further — a transparent, molecular-level layer that actively resists dust, sheds rain evenly, and boosts light absorption beyond what a spotless uncoated panel can achieve on its own.

Four Active Properties

  • Anti-Reflective — reduces light reflection so panels absorb more usable sunlight and generate more electricity, independent of cleanliness.
  • Anti-Dust & Anti-Static — suppresses static charge, giving dust particles less surface to cling to in the first place.
  • Photocatalytic Reaction — uses sunlight itself to automatically break down organic dirt and stains.
  • Superhydrophilic Surface — water sheets off evenly instead of pooling, carrying dust away every time it rains.

Life After Coating

Once applied, there's no more manual brushing, scrubbing, or chemical cleaning needed. A plain water rinse during extended dry spells is typically all that's required — the coating handles everyday dust and grime on its own.

How Long It Lasts

The coating typically lasts a minimum of 5 years, often performing well past 10 years, depending on dirt and pollution buildup at your specific site. The 3-year warranty included with Ultimate Protection is a guaranteed minimum commitment — the coating is very often still performing well beyond that window.

"After a year of using their service, they finally came for the first inspection. Despite living along a busy street with constant traffic passing by, my solar panels are still in pristine condition! Their nano-technology really makes a difference."

Ann AlejandrinoGoogle Review
★★★★★

"I'm impressed! My solar panels are effectively more reliable since I've had them nano coated by the company. It has lowered down the cost of my electricity up to 30%! The team was very reliable and easy to talk to as well."

Frequently Asked Questions

Does coating void my panel warranty?

It depends on the installer, but almost all of our clients' installers have had no issue with our coating. Since it's applied only at the surface level — no connections, wiring, panel openings, or inverters are involved — it typically falls outside what a manufacturer's warranty would even cover.

Are new panels too early to coat?

No — coating works best on glass that's still in good condition, so newer panels often get the fullest, longest-lasting benefit. Waiting until panels are already worn or scratched means the coating has a less ideal surface to bond to.

Can I add coating later if I only get cleaning now?

Yes — coating can be added to a system that previously had cleaning only, as long as the glass is in good condition. There's no requirement to start with coating on day one to benefit from adding it down the line.
