Core mechanisms · 01

Four mechanisms, matched to site profile.

Coatings work through different surface-chemistry mechanisms. The mechanism that suits your asset depends on rainfall pattern, dominant pollution type, panel technology and access cost. We match formulation to context, not the other way around.

M-01

Hydrophilic — water-film sheeting

Super-hydrophilic surface chemistry (contact angle below 8°) allows rainwater to spread into a continuous water film that lifts particulates from the panel surface. Designed for rain-rich climates where natural precipitation can do the cleaning work.

Key specs

  • Contact angle < 8°
  • Continuous water-film formation
  • Rain-assisted particulate sheeting

Best for

General PV · coastal & humid Australian climates

M-02

Hydrophobic — lotus-effect beading

High water-contact-angle formulations cause water to bead into spheres that roll across the surface, picking up loose particulates. Designed for dust-prone, lower-rainfall climates where shedding outperforms sheeting.

Key specs

  • High water contact angle
  • Lotus-effect droplet roll-off
  • Self-cleaning particulate transport

Best for

Inland dust-prone climates · semi-arid Australian sites

M-03

Photocatalytic decomposition

A TiO₂-based active layer breaks down organic deposits — bird droppings, organic dust, biofilms — under UV exposure. Provides ongoing surface activation across the coating's service life, rather than a one-time cleaning event.

Key specs

  • TiO₂ photocatalyst layer
  • Organic decomposition under UV
  • Ongoing surface activation

Best for

Bird-active areas · agricultural / organic dust profiles

M-04

UV-to-visible spectral conversion

One supplier partner has disclosed a light-conversion mechanism that converts sub-400 nm UV wavelengths into usable visible-spectrum light — potentially broadening the absorption window of underlying PV cells. Single-supplier disclosure; broader Tier 2 cross-validation is pending.

Key specs

  • Sub-400 nm UV conversion
  • Visible-spectrum redirection
  • Single-supplier disclosure

Deployment · 03

Three ways to put coating on glass.

Application method is selected on site economics — access constraints, asset scale, panel type and timeline. We size the pilot deployment around the realities of your operation, not the other way around.

D-01

Manual scraping application

Hand-applied with calibrated scraping tools across cleaned, dried panel surfaces. Used for small-to-mid distributed sites where access cost and crew mobilisation are key constraints.

Coverage

20 – 80 m² / L

Heavier soiling profiles use 20–40 m²/L; lighter soiling 60–80 m²/L

Best for

Commercial rooftops · small-to-mid distributed PV

Constraints

  • Manual labour required
  • Suitable for small-to-mid scale
  • Curing: 24 h ambient

D-02

Robotic / mechanised application

Supplier-engineered robotic applicator combines surface cleaning and coating deposition in a single pass. Designed for large-area utility-scale and multi-site portfolio deployments.

Coverage

Scaled to area

Robot pre-cleans and coats; throughput depends on row design and panel orientation

Best for

Utility-scale farms · multi-site portfolios

Constraints

  • Requires supplier equipment access
  • AU import + logistics review required
  • Pilot-validation before scaled rollout

D-03

Spray application

Pressurised spray application for hard-to-access retrofits and ARC-glass surfaces. Particularly useful for coastal solar assets and irregular module configurations.

Coverage

15 – 25 m² / L

Overspray accounted for; higher consumption rate than scraping

Best for

ARC-glass coatings · retrofit · coastal assets

Constraints

  • Higher material use
  • PPE + ventilation requirements
  • Manufacturer warranty review required for ARC-coated modules

Technical backing · 04

Science with receipts.

Behind each formulation sits a documented R&D base — published standards, patent filings, peer-reviewed publications and institutional research linkages. SolarShield is responsible for matching that documentation to Australian compliance and pilot evidence requirements.

I-01

Aligned with a published national standard

Supplier R&D base is aligned with a published Chinese national standard for TiO₂-based photocatalyst dispersions, providing a formal reference framework for material composition and performance characterisation.

I-02

Patents & peer-reviewed publications

Across the supplier portfolio: 20+ Chinese invention patents, international PCT filings and peer-reviewed publications in coating-chemistry journals. SolarShield is documenting which IP applies to which formulation as part of supplier due diligence.

I-03

Research institution linkage

One supplier partner's R&D team includes researchers with affiliations to a national photochemistry research laboratory and bionic-interface materials groups at a tier-1 Chinese university. Forms the academic backbone of the photocatalysis approach.

I-04

Self-healing mechanism (R&D path)

One supplier R&D path proposes a negative-expansion stress-compensation self-healing mechanism: embedded nano-tubes contract under stress and release surfactant repair agents into micro-cracks. Currently at academic-trial maturity, not yet in the commercial product matrix.
