PV SoilSayer

Before the system is built, state-of-the-art modeling software calculates soiling losses throughout the year to estimate O&M budgets and align PV system performance models with optimal cleaning cycles.

PV Pattern Soiling Station

After the PV system is constructed, Cell-level measurements provide insight into soiling patterns, accurately measure non-uniform soiling losses, prevent hot spots due to soiling and model soiling losses on a wide variety of different PV technologies.

PV Soil Monitoring Portal

Web portal monitoring provides easy access to on-site soiling loss measurements, insightful analytics to optimize cleaning cycles and user configurable alerts and alarms.

PV SoilSayer

Improve the accuracy of baseline performance models

Estimate optimal clean cycles based-on cost trade-offs​

Accurately estimate soiling losses as a function of angle of incidence and site specific weather conditions​

Align performance models and O&M budgets with optimal clean cycles​

Step Into the Future....

The PV SoilSayer is a revolutionary new software that helps PV owners and operators estimate cleaning costs well ahead of PV system construction. The PV SoilSayer utilizes advanced computer learning algorithms combined with annual weather data, PV performance models, soiling losses estimations, and system cost trade-offs to calculate the optimal cleaning cycles.

Why PV Soil Monitoring?

0 %

Up to 35% energy losses due to soiling in a single month in desert regions

Soiling losses are specific to design, technology and local weather conditions​

Non-uniform soiling is a major contributor to hotspot formation and accelerated degradation​

0 %

Cleaning costs account for up to 30% of total system O&M budget

How it works


Specialized soil monitoring hardware platform accurately measures losses due to soiling at any point within the PV system


Measurements are sent to remote servers where the cost trade off between soiling losses vs. cleaning are calculated


Automated notifications alert operators of upcoming cleanings in order to minimize costs and maximize production
