In MENA regions, dust accumulation is a constant operational
challenge. Fine sand particles, frequent dust events and low
rainfall lead to rapid soiling of PV modules, causing measurable
energy losses within weeks after installation or cleaning.

Delayed cleaning in desert environments increases thermal
stress and surface wear, especially when fine sand interacts
with dew or humidity. Regular automated cleaning helps mitigate
these risks and support long-term module reliability.

The result is more stable performance, lower operational risk,
and improved bankability for long-term forecasts (P50/P90).

Note: Manual cleaning typically cannot be performed with sufficient frequency
or uniformity. As a result, timing gaps, uneven coverage and access limitations
lead to persistent residual losses — commonly on the order of ~6% over
extended operating periods.

In desert environments, soiling losses scale with time between
cleanings — and become a direct revenue and KPI issue.

How losses accumulate
between cleanings

Chronic underperformance versus
financial models and higher O&M
intervention burden

Long term

Losses typically reach ≥25% in many MENA
locations without cleaning

≈4 weeks

Early yield drop and rising mismatch
across strings as dust builds up after
events

1–2 weeks

Reduces height-work requirements and lowers
incident risk for routine cleaning.

HSE simplification

Avoids microcracks and handling-related
surface damage during routine operations.

No walking on panels

For industrial rooftops, manual cleaning adds safety
risk and can damage PV assets through handling
and accidental loading. Automation removes
the need for routine human access to rooftops.
