Projects — Contextualized Evidence for SolarEX Coatings
SolarEX project references are presented as engineering evidence: controlled comparisons, study-specific rooftop data, model-based commercial scenarios, and qualitative field observations. Each reference demonstrates SolarEX performance through controlled comparisons, monitored studies, commercial models, and field observations.
Proof Must Match the Site Context
SolarEX performance is evaluated through site-relevant technical evidence. Outcomes depend on the intersection of climate zone, soiling and contamination profile, UV irradiance availability, cleaning regime, module type and age, application quality, and monitoring method and duration. The project references provide a strong basis for pathway selection, pilot design, and commercial evaluation.
SolarEX presents its project references with explicit evidence-type labeling so that asset owners, engineers, and procurement leads can assess applicability to their own sites.
Context-Dependent Performance
Yield uplift, cleanliness improvement, and cleaning burden reduction are all functions of site-specific variables. A result observed under Scandinavian low-UV conditions does not predict outcome in a high-irradiance desert environment, and vice versa. Reference results demonstrate how SolarEX performs under defined operating conditions and support product selection for comparable site profiles.
Evidence-Type Transparency
SolarEX categorizes all evidence as: controlled comparison, expert study with interval monitoring, qualitative field observation, or financial model. Each category gives buyers a clear view of technical performance, observed field behavior, and commercial value modelling.
Pilot-Before-Scale Logic
Reference evidence supports pathway selection and pilot design — and provides a practical framework for site-specific deployment planning. Controlled pilot deployment with a defined monitoring protocol is the recommended path before large-scale coating procurement or deployment.
Three Reference Contexts
SolarEX maintains three distinct project reference contexts, each representing a different evidence type, geography, and coating pathway. Together, these references demonstrate product performance across different climates, mechanisms, and commercial use cases.
Three Project Reference Contexts
Controlled Comparison
Scandinavian Quartz — Controlled Test
Geography: High-latitude Northern Europe
Pathway: Quartz / passive SiO₂ (no-UV)
Evidence Type: Controlled coated vs. uncoated comparison
Result Type: Quantitative, test-specific
Commercial relevance: Applicable only under equivalent low-UV, temperate conditions
Expert Study
Titan Expert Rooftop Study
Geography: UV-sufficient rooftop environment
Pathway: SolarEX Titan — active TiO₂ photocatalytic coating
Result Type: Qualitative only — visible cleanliness improvement post-rain
Commercial relevance: The reference demonstrates visible cleanliness improvement in a high-dust, water-scarce operating environment.
Controlled Comparison
Test-Specific Data
Scandinavian Quartz Controlled Test
The Scandinavian Quartz test was conducted in a high-latitude Northern European environment selected specifically to evaluate passive SiO₂ coating performance under conditions of limited UV availability. Quartz was selected as the appropriate pathway because it functions without relying on UV-activation, making it suitable for temperate, low-irradiance climates where UV-dependent coatings may underperform. The controlled comparison pitted coated modules directly against uncoated equivalents under equivalent environmental conditions over a 26-month monitoring period.
The test recorded an approximately 10% output advantage for coated modules within that specific context. Reduced cleaning burden and water consumption were also observed in source framing. The result demonstrates Quartz’s commercial relevance in high-latitude PV environments and supports its positioning as the preferred UV-independent pathway for passive soiling control.

Study-Specific Data
Titan Expert Rooftop Study
The Titan expert study is the most instrumented reference context in the SolarEX evidence base. Conducted on a UV-sufficient rooftop installation, the study monitored 63 coated modules over 360 continuous days using 15-minute interval data collection — a granularity sufficient to isolate coating contribution from environmental noise across diurnal and seasonal cycles. String-level segmentation enabled differential analysis across three independently monitored circuit paths.
The study recorded an average yield uplift of +5.15% across all coated modules versus matched control modules. String-level results were +5.62%, +5.22%, and +4.62%, reflecting internal variance consistent with rooftop microclimate and application uniformity factors. The study provides validated 360-day evidence for Titan, supporting product evaluation, commercial modelling, and pilot planning in UV-sufficient PV environments.

Field Reference
Post-Rain Cleanliness Improvement
Middle East Cleanliness Reference
The Middle East cleanliness reference was conducted in a high-dust, high-irradiance, water-scarce operating environment — conditions representative of utility-scale and commercial installations across the Arabian Peninsula and adjacent arid regions. These environments present significant soiling challenges: fine particulate accumulation is rapid, cleaning water is expensive and operationally constrained, and manual intervention frequency is a key cost driver.
Coated panels in this context demonstrated visibly improved post-rain cleanliness compared with untreated reference panels in the same installation. The hydrophilic surface characteristic of the SolarEX coating facilitated more complete particulate removal during precipitation events, reducing residual soiling visible to field inspection.
Commercial Models
SolarEX ROI models translate coating performance into commercial value using defined regional inputs for irradiance, energy price, coating cost, and expected uplift.

From Reference Evidence to Site-Specific Pilot
Reference project data supports pathway selection and pilot design. It creates a practical path from documented SolarEX evidence to site-specific scale-up planning. The following four-step pathway describes the recommended transition from reference evidence to actionable, site-validated performance data.
Each step produces discrete deliverables that feed the subsequent phase. Site assessment outputs inform application design; controlled application creates the coated/control differential; performance monitoring generates the site-specific dataset; and evidence review produces a defensible go/no-go recommendation for large-scale deployment. This process is the correct engineering path before significant capital commitment.
Recommended Pilot Measurement Framework
A well-designed pilot generates site-specific data that is comparable to reference contexts and defensible to internal and external stakeholders. The following measurement parameters constitute the minimum recommended framework for a SolarEX coating pilot. A complete pilot dataset improves confidence, comparability, and commercial decision quality.
Baseline Yield
Pre-coating yield data for all modules, irradiance-normalized, minimum 30-day baseline before application. Establishes the differential reference for post-coating comparison.
Cleaning Frequency & Water Use
Documented cleaning events, volumes, and labor inputs for both coated and control sections. Enables operational cost benefit quantification independent of yield data.
Contamination Profile
Soiling type, deposition rate, and seasonal variation characterization. Determines coating pathway suitability and expected self-cleaning mechanism activation frequency.
Irradiance / UV Availability
On-site pyranometer data and UV index logging. Critical for validating coating pathway selection (UV-dependent vs. passive SiO₂) and normalizing yield comparison.
Coated vs. Control Modules
Matched module pairs or strings — same manufacturer, age, orientation, and tilt. Isolation of coating contribution requires statistical equivalence in all other variables.
Monitoring Interval & Duration
Minimum 15-minute data intervals recommended, consistent with the Titan expert study methodology. Minimum 90-day duration; 360 days preferred for seasonal representativeness.
