Accurate Soiling Assessments, Predictions, and Cleaning Analytics

Explore our comprehensive, data-driven solutions

Microscopy

Cheaper and faster alternative to IV curve tracing

Our proprietary method uses image analysis and an optical model to quantify soiling from microscope imagery taken with a portable handheld device. No installs and no reliance on weather windows or operational data availability.

Operational Analytics

Extract soiling trends from your site's performance

We isolate soiling losses from operational data, giving you a clear picture of past losses and current trends. After each cleaning, we measure the resulting performance uplift so you can see the return on your investment.

Predictive Modeling

Plan for future soiling, specific to each site

We combine insights from microscopy and operational analytics with local climate and atmospheric data from NASA's global climate model. A predictive soiling model is tuned for each site (or subsection of a site) for accurate forecasts of losses.

Proactive Optimization

Forecast, prioritize, and budget for cleanings years in advance

We translate DC soiling losses into AC generation impact and factor in site PPA rates and up-to-date cleaning quotes to provide economically optimized cleaning schedules that maximize return on investment across the fleet.

What our customers are saying

“The Solar Unsoiled application helped me identify and prioritize the sites that require washing with an understanding of financial losses and expected payback on the washing maintenance. This helped avoid countless hours of discussions over financial justification. We were able to budget the expenses and schedule our crews nearly three full quarters in advance.”


Dustin Wambeke

Sr. Director of O&M Technical Services at Cypress Creek Renewables

“Solar Unsoiled’s platform has helped us understand our historical soiling and predict future losses. We are getting a ton of value from now being able to make proactive washing decisions. The Solar Unsoiled team has been awesome to work with, and they have drastically improved the way we mitigate soiling across our fleet.”
