APS' Own Solar System

APS is now 100% Powered by the Sun! See what our very own system is producing right now. Use the "How Solar Works" or "Graph" functions to view APS's Solar System performance over time. Monitoring systems give both the user and the installer the information needed to assess system performance. Additionally since most monitoring systems are web-based, you can check your system performance from anywhere.
SolarEdge Monitoring

SolarEdge Monitoring System

Take a look at this APS customer, located in Sonora, CA.. The SolarEdge System allows each panel to be individually monitored. It also shows system performance over time for each panel, as well as the system as a whole. Systems based on this architecture are the most tolerant of shading on panels, maximizing performance when localized shading is a factor. See it in action (opens a new window).
