Ejina Solar Tech
Advanced anti-soiling, anti-reflective, and self-cleaning solar photovoltaic cells for maximum energy efficiency
Who We Are
Problems To Solve
Soiling Impact
Soiling on solar panels can reduce efficiency by up to 70%. Organic/inorganic buildup lowers light transmission and causes power loss (7% annually), shading, degradation, and hotspots.
Dew and Cementation
Dew increases dust adhesion, while hygroscopic particles cement onto panels after absorbing moisture, making cleaning harder and costlier.
Optical Reflection Loss
Light reflection at the air-glass interface wastes 10-20% of incident light. Anti-reflective textures can worsen dust accumulation, further reducing solar output.
Weather Conditions
Snow and ice buildup on PV cells can reduce electricity generation by up to 80%, even with just 2 cm of snow cover. Current snow removal methods are manual, energy-intensive, or environmentally harmful.
Ineffective Cleaning Methods
Traditional cleaning is water-heavy, costly, and unsustainable. Alternatives like EDS are not yet viable, with global soiling losses reaching CAD 3 - 5 billion yearly.
Our Solution
Advanced Nano-Coating Technology
Ejina Solar Tech is applying an ultra-thin (~500nm) nano-textured fluoropolymer coating that is reducing soiling by 50–70% and is preventing dust cementation, while maintaining high light transmission with minimal cleaning.
Multi-Height Configuration Design
We are implementing an innovative multi-height surface design that is minimizing dust adhesion and dew formation, enabling self-cleaning panels with detachment force nearly 100 times lower than uncoated cells.
Enhanced Optical Performance
We are reducing light reflection by 70–90% while maintaining anti-soiling properties, allowing more sunlight to reach PV cells without attracting excess dust like traditional textured glass.
Weather Resistance Innovation
We are preventing snow and ice buildup on PV cells with our coating, eliminating the need for manual or chemical removal and ensuring year-round protection with lower maintenance.
Superior Durability Technology
We are outperforming conventional coatings with drop-wise condensation technology that is delivering combined anti-soiling, anti- reflection, anti-dew, anti-icing, and self-cleaning performance in a single, durable application.
