Sunlight and rain keep module surfaces clean — less manual maintenance, longer module life, higher output.
A 50 nm textured surface cuts reflection; the 100 nm film raises visible-light transmission.
Contact angle below 20°: rain gets under grime and floats it off.
Surface resistance below 10⁹ Ω — dust and sand do not cling, and shed easily.
Low surface energy keeps airborne organics from sticking.
100% inorganic; no chalking after 600 h; about five years of full effect.
After application, the transmittance gain plus self-cleaning typically adds around 3% or more generation.
Sand and bird droppings create hot spots and short-circuit risk; frequent washing damages panels. The coating stops soiling at the source.
Super-hydrophilic, anti-static, higher transmittance
PV glass — higher generation efficiency
Silica, titanium oxide, siloxane compounds
| Metric | Result |

| 发电量提升 | 约 +3% |
| 表面电阻 | < 10⁹ Ω |
| 水接触角 | < 20° |
Feibo lab and project data; real gains depend on site conditions.
Confirm feasibility, assess environment, define a control array.
Trial area verifies conversion efficiency and current output.
Soft neutral water with dedicated cleaner — no dust, no oil film.
Once dry, semi-automated brush or spray for an even film.
About 4 h to form a dense photocatalytic film.
Monitor generation gain and deliver a full project report.
Less soiling plus higher transmittance keeps output up without constant washing.
The anti-static layer keeps dust from clinging; rain or plain water removes what lands.
Wholesaler, distributor, builder, developer, engineer, designer or asset manager — Feibo tailors self-cleaning solutions to your project
