Key features

Know exactly when and where to clean
Optimise yield

Maintenance free
Integrated into leading plant management software

DustIQ provides the information for solar energy plant management systems so that you can decide exactly when and where to clean. You can set alarms in your system software to indicate when a certain soiling ratio has been reached and cleaning is needed. Thanks to the cost-effective price, you can install a network of DustIQ units to monitor the variation in soiling over across the plant.
