Utility-scale PV
On large sites, soiling losses become a KPI and revenue issue.
Cleaning is not a single event — it is a routine that must stay
consistent across blocks, seasons and dust events.

Why Automation

High-frequency automated cleaning helps
recover energy that would otherwise be
lost to soiling — commonly ~25–35%
in harsh conditions (site-dependent).

Routine-based operation
SunShiner is a ground-mounted utility PV cleaning system
designed for frequent dry-cleaning routines. It operates
row-by-row and can be deployed across blocks to support
consistent performance at scale.
