Case Studies


The art & science of soiling sensor placement


How many soiling stations are needed for a particular site? Determining correct soiling sensor placement is both an art and a science, but this case study should provide a good overview of the various factors we examine with each new project.

Manual cleaning comparison


Comparing the soiling loss measurement of Fracsun’s ARES device with the inverter outputs of two similar PV arrays, wherein one of the arrays is manually cleaned
periodically and the other is naturally soiled. In this study, we see how closely ARES soiling loss measurements correlates to inverter measurements.

Solar Risk Assessment 2021


What is the Solar Risk Assessment?

Industry experts in solar production risk have partnered to publish the new ‘Solar Risk Assessment 2021’ report to advance the solar industry. Designed intentionally for a non-technical financial community, this report will be refreshed every year to provide investors with the latest insights on the evolution of solar generation risk. Fundamentally, it is our hope that this report will serve as a guide for investors who recognize the importance of allowing data-based insights to inform the deployment of capital.
