ARES directly measures soiling loss in order to optimize solar efficiency

Direct Soiling Measurement
ARES generates a daily soiling rate value by making a comparative measurement of clean and a soiled reference cells. This is done automatically without the need for manual cleaning and measurement.
Wash with Confidence

With a direct soiling measurement and our special algorithms that factor in the array data, you can wash with the utmost confidence. Get notifications and schedule cleanings of your array when it's financially responsible.

Maximize ROI

Wash with real data. Cleaning is often incorporated without true knowledge of the current effect of soiling loss at the time of scheduled cleaning. Cleaning too often or not often enough will both impact ROI (and LCOE) negatively.

Measure
ARES generates a daily soiling rate value by making a comparative measurement of clean and a soiled reference cells. This is done automatically without the need for manual cleaning and measurement.
Calculate
Using this value along with other site parameters (energy yield, cost to clean, value of energy, rain, etc.) server-side calculations then determine the most economic times to clean the system which is sent to the system management.
Aggregate
Utilizing anonymous data collection from ARES devices in the field, Fracsun is able to provide site specific soiling estimates. This will allow unprecedented understanding for project developers and system financiers.
