Pain-point clusters · 01

Mapping overseas references to Australian pain points.

We group the supplier's case-study portfolio by the dominant soiling or operating context, so Australian operators can match their own asset profile to comparable overseas conditions. Note the Australian-relevance caveats under each cluster — climate, compliance and access constraints differ.

Methodology · 03

What these numbers do — and do not — confirm.

SolarShield operates a three-tier evidence hierarchy. Overseas supplier case studies sit at Tier 2: useful for qualified statements, but never substituted for Australian pilot data. We also publish the methodology questions still open against the supplier dataset.

Evidence hierarchy

Tier 1

In preparation

Australian pilot data

NATA-accredited testing, customer-approved Australian case studies, panel-manufacturer warranty confirmation, AICIS review record and Australian-format SDS/GHS. Required for strong public claims.

Tier 2

Currently available

Overseas supplier evidence

Overseas third-party reports (SGS, DEKRA, TÜV), supplier technical documents, overseas commercial case studies, raw A/B trial data and controlled-trial datasets with cleaned-only control groups. Supports qualified statements only.

Tier 3

Internal positioning only

Marketing material

Supplier brochures, before/after photos and percentage claims without methodology. Used only to inform internal positioning; never quoted as public proof.

Open methodology questions

Q-01

Net coating effect vs cleaning + coating

Across the broader case-study portfolio, reported figures generally combine surface cleaning with coating application. Controlled A/B/C trial data with cleaned-only control groups has been disclosed by one supplier partner for select formulations — published separately under our trial methodology disclosure. For the remaining case set, the independent net coating effect has not been disaggregated in supplier material.

Q-02

Irradiance / weather normalisation

Whether energy data was normalised for irradiance, ambient temperature, rainfall and seasonality is not consistently stated across the supplier case summary. Where controlled-trial datasets exist, normalisation is documented for the corresponding inverter pairs only.

Q-03

Monitoring period

The duration of post-application monitoring used to derive each percentage varies. Supplier-disclosed windows range from 14 days (controlled trials) to ≈12 months (selected commercial customer studies). SolarShield Australian pilots target a minimum 3-month, preferably 6–12-month, monitoring window.

Q-04

Independent verification

Reported gains have not been confirmed by an independent third party across the full dataset. NATA-accredited testing and customer-approved Australian case studies sit above supplier case lists in our evidence hierarchy.

Q-05

Transferability to Australia

Pollution profile, climate, panel technology, tilt, cleaning baseline and access constraints differ materially between Chinese industrial sites and Australian commercial rooftops or utility-scale farms. Local pilot data is required before any Australian performance claim is made.

Open trial methodology disclosure

Controlled A/B/C trials, test methods and the Australian pilot protocol — Tier 2 → Tier 1.

Performance disclaimer

Product performance may vary depending on site conditions, panel type, weather exposure, pollution source, cleaning frequency and application method. Any performance figures from overseas supplier case studies are indicative only and do not guarantee Australian site outcomes. Commercial application is subject to product-specific compliance review, site assessment and pilot validation.

Australian pilot · 04

Help us produce the Tier 1 evidence.

SolarShield is seeking selected commercial rooftop, industrial solar and O&M partners to participate in small-scale Australian pilot projects. Each pilot is designed as a controlled A/B trial — cleaned-only control versus cleaned-plus-coated — so the resulting data can sit at Tier 1 of our evidence hierarchy.
