Robot Fleets Allow Swift Deployment to Combat Soiling
Full-sized truck equipped with
water tank and battery charging
stations to service robots
Four robots operate at any one
time; robots require minimal
maintenance between shifts
Two operators manage the robot
fleet and service robots with
batteries, water as needed
throughout site

Robotic Cleaning Just Part of a Broader Automated and Integrated O&M Solution
Predictive Modeling
Simulation modeling tools
help to optimize panel
cleaning schedule and
minimize the impact of
soiling on plant production
Real-time Monitoring
Remote performance
monitoring can
automatically trigger
O&M response
In-field response
Module cleaning is one
example of O&M activity
that can be automated;
still room for more
innovation
Oasis cleaning robots
