Anti?Dust & Self-Cleaning Modules

01.Dust Accumulation Pain Point – Power Generation Loss

How does dust directly affect power generation?

Dust covers the module glass surface and directly blocks sunlight; effective irradiance drops, and module output power decreases continuously with dust accumulation.

Local overheating or hot spots reduce overall efficiency and accelerate module performance degradation.

Increased diffuse reflection prevents some light from entering cells effectively, causing extra optical loss.

02.Dust Accumulation Pain Point – Safety Risks

Hot spots are a critical defect in PV modules;
they cause sharp local temperature rise, material damage, and fire risks.

Cells in hot?spot areas stop generating power and act as a “load”,
consuming electricity from other cells and reducing total output by 10%–30%.

VS

03.Dust Accumulation Pain Point – High O&M Cost

Disadvantages of Current Cleaning Methods

High cost, poor cleaning effect, frequent cleaning, easy to have glass scratching, etc.

There is an urgent need for a solution that reduces cleaning frequency, keeps surfaces clean,
improves long?term power output, and delivers low cost & high return.

Integrated Solution 1 – Dust?Resistant Frame (2% Gain)

Dust?Resistant Frame

Special frame design: short side parallel to glass surface,
less dust buildup, easier cleaning & maintenance.

Conventional Frame

Long &Short sides both have A-surface design,Obstructs the sliding of dust and snow,
leading to dust accumulation in the long term

Integrated Solution 2 – Self?Cleaning Glass (4% Gain)

Super Hydrophilic + Anti?Static + Photocatalytic + Nano?Coating Technology

Micro?Nano Structure

Principle: Nano?scale rough structure reduces contact area between dust and glass, weakening molecular adhesion.

Effect: Reduces physical dust adhesion

Anti?Static

Principle: Standard glass builds static electricity and attracts charged dust; conductive additives discharge static instantly.

Effect: Suppresses static; charged dust does not adhere easily.

Super Hydrophilic

Principle: Super hydrophilic coating spreads water into a uniform film instead of droplets.

Effect: A small amount of rain or dew are enough to create a cleaning water film.

Photocatalytic

Principle: Special coating activates photocatalytic reaction under sunlight.

Effect: Decomposes organic contaminants in dust.

Performance Advantages vs. Traditional Coatings

Multi?dimensional comparison shows clear advantages of self?cleaning coatings.

	Traditional AR Coating	Self?Cleaning Coating
Self?Cleaning Function	Not Available	Available
Anti?Static Ability	Not Available	Available
Durability	Average hardness, wear resistance, and durability	Excellent hardness, wear resistance, and durability
Maintenance Cost	Requires frequent cleaning	No frequent cleaning needed
