Fleet Management Tool for Solar Inverters

Developed under project “Harnessing Sensor Data for Degradation Analytics and Operations & Maintenance Optimization in PV Systems: A Prognostic Approach”, funded by the Solar Energy Technology Office (SETO), U.S. Department of Energy.

Benefits to Industry

Significant reduction of maintenance cost, see below for the example maintenance cost reduction over simulation for 60 years.
