Rooftop solar is often treated as a set-and-forget asset, but climate
exposure makes performance drift unavoidable. Dust, coastal humidity,
seasonal rain residue, and winter events accumulate into losses that
are rarely cleaned at the frequency needed for stable KPIs.

One rooftop system — different climate challenges

Outcome:
Automated routines stabilize surface condition and reduce variability
in performance reporting.
Automated routines stabilize surface condition and reduce variability
in performance reporting.
Humidity turns dust into stubborn residue
Moisture combined with dust can form residue that is harder to remove consistently.
Uneven surface condition increases mismatch across strings and arrays.
Manual cleaning quality varies by crew, timing, and access conditions.
Outcome:
Frequent automated dry cleaning prevents loss build-up and keeps output closer
to expected generation.
Frequent automated dry cleaning prevents loss build-up and keeps output closer
to expected generation.
Dust builds up fast after events
Fine dust accumulates gradually and spikes after wind-driven events.
Water and labour logistics limit achievable cleaning frequency on rooftops.
Losses build up between cleanings and remain invisible in day-to-day operations.
Outcome:
Automated clearing supports earlier recovery after snowfall events
and more predictable winter operations.
Automated clearing supports earlier recovery after snowfall events
and more predictable winter operations.
Snow can block generation completely
After snowfall, PV rows may be fully covered, causing immediate production losses.
Recovery depends on weather rather than operational control.
Manual clearing is slow and safety-intensive on rooftops during winter conditions.
SunShiner for rooftops
For rooftops, the system is deployed as a subscription service:
sizing, cleaning frequency, maintenance and replacements
are bundled into a predictable monthly O&M model.

SunShiner removes recurring rooftop cleaning from manual
