Two Revolutionary Coating Technologies
SolarEX SiO₂
Silicon dioxide nanocoating creates hydrophobic surface that repels water, oil, and dust. Self-cleaning lotus effect keeps panels cleaner with minimal maintenance.
  • 2-10% efficiency gain
  • Hydrophobic protection
  • UV-stable durability
SolarEX Titan TiO₂
Titanium dioxide coating provides photocatalytic self-cleaning that actively breaks down organic contaminants using sunlight energy.
  • 5.15% proven efficiency gain
  • Photocatalytic cleaning
  • Superhydrophilic water sheeting
How SiO₂ Nanocoating Works
Advanced Nanostructure Technology
SolarEX SiO₂ forms a transparent 100-150nm thick film of silica nanoparticles. This ultra-thin layer creates hydrophobic and oleophobic properties that repel water, oil, and dust particles.
The coating mimics the lotus effect - water beads and rolls off, taking contaminants with it. This passive self-cleaning reduces manual maintenance while maintaining optimal light transmission.
01
Surface Preparation
Thorough cleaning removes all residues for optimal bonding
02
Nanocoating Application
Spray or wipe application at 5-15 mL per m² coverage
03
Rapid Curing
30-second initial dry, 24-hour full cure without UV equipment
TiO₂ Photocatalytic Action
UV Activation
Sunlight excites TiO₂ electrons, creating powerful hydroxyl radicals
Organic Breakdown
Radicals decompose organic contaminants into harmless water and CO₂
Water Sheeting
Superhydrophilic surface spreads water evenly for streak-free cleaning
Unlike passive coatings, SolarEX Titan actively cleans panels continuously during daylight hours. The photocatalytic process breaks down bird droppings, pollen, and organic films that traditional coatings cannot handle.

Real-World Case Study
Scandinavian Utility Project: Norwegian Solar Farm
A major utility-scale PV array spanning 10 MW, located near Tromsø, Norway, implemented SolarEX on a 1 MW section of its panels. This region is known for its challenging climate, including prolonged periods of low sunlight, heavy snowfall, and freezing temperatures, which typically lead to significant energy losses due to soiling and snow accumulation.
Over a rigorous 6-month trial period, from October to March, the SolarEX-coated panels consistently delivered a 10% higher energy yield compared to an adjacent control group of uncoated panels under identical environmental conditions. This translated to a sustained performance boost, even amidst harsh winter conditions.
Plant operators reported a remarkable 75% reduction in annual water usage for panel cleaning, moving from weekly to monthly cleaning cycles. This substantial decrease not only minimized operational costs associated with water consumption and specialized cleaning equipment but also significantly reduced labor hours required for maintenance, leading to substantial personnel savings. The self-cleaning properties of SolarEX also prolonged panel lifespan by reducing abrasive cleaning, and minimized downtime traditionally needed for manual cleaning.
The testing methodology involved a side-by-side comparison of 1,000 coated panels against an equivalent control group of 1,000 uncoated panels within the same array. Advanced data logging systems meticulously recorded energy output, panel temperature, and environmental factors (irradiance, ambient temperature, precipitation) every 15 minutes, ensuring high-fidelity performance metrics.
10%
Energy Increase
Consistent higher output throughout the entire 6-month trial, boosting overall energy production even in low-light conditions.
75%
Water Reduction
Dramatic decrease in cleaning water usage and frequency, leading to significant cost savings and environmental benefits.
80%
Soiling Reduction
Coated panels maintained significantly cleaner surfaces, reducing energy losses from dust, grime, and snow accumulation.

Extended Financial Impact: For a typical 1 MW system operating in Norway, the 10% energy gain translates to an additional 100-200 kWh per day, generating an extra €30-€60 in daily revenue based on average EU energy rates (€0.30/kWh). Over a year, this equates to an additional €10,950 - €21,900 per MW. When factoring in the 75% reduction in cleaning costs (estimated at €5,000-€10,000 annually per MW) and reduced labor, the total annual savings and increased revenue can easily exceed €20,000 per MW, ensuring a rapid return on investment. The project manager stated, SolarEX proved indispensable for maintaining optimal performance and significantly cutting operational expenses in our challenging Nordic environment.
