PV SoilSayer

Solar Cleaning Optimization made easy with Enlighten Energy: Web-based, state-of-the-art modeling software calculates soiling losses in PV modules throughout the year to estimate O&M budgets and align PV system performance models with optimal cleaning cycles.


On-site, sub-panel measurements provide insight into soiling patterns, accurately measure non-uniform soiling losses in PV modules, prevent hot spots due to soiling and model soiling losses in PV modules 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 solar panel cleaning cycles and user configurable alerts and alarms.

PV SoilSayer
Clean Cycle Optimization analysis

Improve the accuracy of baseline performance models and increase asset valuation

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

Accurately estimate soiling losses in PV modules 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 Web-based software platform, developed by Enlighten Energy that helps PV owners and operators estimate energy losses due to soiling well ahead of PV system construction as well as providing automated clean cycle updates based-on long-term weather forecasts, for operational projects. 

The PV SoilSayer utilizes computer learning algorithms combined with local weather, PV performance models, soiling loss estimations, and system cost trade-offs to forecast energy losses and calculate the optimal cleaning cycles.

Why PV Soil Monitoring ?

0 %

Up to 60% energy losses due to soiling in a single month in desert region

Soiling losses in PV panels are specific to design, technology and local weather conditions

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

0 %

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

Waterless Automated Soiling Pattern Pod (WASPP)

Optimize PV system performance

Prevent hotspots

Minimize solar cleaning costs

Maximize returns from PV assets​

How it works


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


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


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