PV power boost · Case study

Hillside PV plant power-boost coating

Hillside modules soiled by dust and bird droppings now self-clean in rain, with less manual cleaning and more output.

Plant typeHillside ground-mounted plant

Applied toCrystalline silicon PV modules

MethodSpecialist cleaning + semi-automatic spray

ProductFeibo PV power-boost coating

Background

The problem

Modules on the hillside were covered by wind-blown sand, dust and bird droppings, cutting light transmission and creating hot spots. The terrain made manual cleaning slow and costly, and frequent cleaning risked damaging the modules.

Scope of work

What we did

Site survey and selection of a comparison test array
Small-area trial to measure power and current gain
Cleaned modules with soft neutral water and specialist detergent — no dust, no oil film
Semi-automatic spray once dry, ensuring even coverage
Ambient cure ~4 h; collected generation data and delivered a report

Results

Results and value

The modules now carry a super-hydrophilic, anti-static film: dust does not cling and rain washes it off. With the anti-reflective effect, plant output rises by about 3% or more while manual cleaning and O&M costs fall sharply.

Desert PV plant power-boost coating

Sandstorms and dust hit desert plants hardest; the anti-static coating stops sand clinging so rain or a light rinse restores clean modules.
