The modules are coated with a "self-cleaning film." Advanced nano-interface modification and sol-gel technology simultaneously endow the modules with triple benefits: super-hydrophilic self-cleaning, dynamic antistatic dust prevention, and optical anti-reflection and anti-reflection enhancement. Rainwater washes away floating dust, static electricity no longer attracts dust, and full-spectrum light transmittance is improved simultaneously. Actual abrasion resistance is ≥15,000 cycles, hardness ≥3H, and it does not peel or degrade over long-term outdoor use. This reduces maintenance cleaning frequency and water consumption while directly increasing power generation throughout the entire life cycle—a single investment yields two benefits.
