Guaranteed clean irradiance measurement
-
Unique patented solution using proprietary technology
Proprietary Measurement Technology
Our PV reference technology provides a real metric to evaluate solar soiling. Unlike other methods such as optical sensors, ARES calculates powerful and actionable data - whereas optical sensors are only able to estimate this data.
PV Reference | Optical Sensor |
|---|---|
PV sensor response is highly correlated to array response | Optical sensor response is poorly correlated to array response |
No calibration needed as it accounts for all soiling materials natively | Needs constant re-calibration to account for different types of soiling materials |
Measures all wavelengths for soiling calculations | Is only able to measure 1 wavelength |
Uses a clean solar cell for reference | Does not use a reference cell |
Calculates real-time soiling data | Uses estimated soiling data |
"After deploying the soiling monitoring hardware, we were able to see that we weren’t washing often enough. Optimizing our cleaning schedules allowed us to maximize overall site performance and reduce costs.”

Testimonials
Will Carleton,
General Manager Solar O&M
Clearway Energy Group
"The equipment has given us monitoring capability to compare soiling levels to generation and helped us determine at what soiling percentage do we engage the contractor so that we don’t have greater generation loss due to contractor scheduling. We can watch the soiling rate and determine ahead of time to schedule the contractor."

“Fracsun's soiling management solution is the first truly complete solution available to the market, and it actually makes managing solar assets easier by using sophisticated software to proactively analyze your data and cost-benefit calculations.”
Cannon Michaels, President
Bowles Farming Company
“Before implementing the ARES solution near an agricultural facility our team had difficulty determining when it was the best time to clean the array. After deploying the soiling monitoring hardware, we were able to see that we weren’t washing enough and we were able to bring cleaning in-house, saving a substantial expense on every cleaning event.”
