You may be thinking that if you're going to make this investment, you'd really like to be able to monitor the performance of your solar system. While this used to be an expensive extra on solar electric (PV) systems, in the last few years it has become standard from the major inverter manufacturers. Whether you have micro inverters or string inverters on your solar system, it is now easier than ever to get robust graphical performance monitoring via the web so your operations manager or any interested stakeholders can see how your system is performing at any point in time. Many are leveraging the educational benefits too.
Solar water heating systems have less sophisticated monitoring than solar electric, but there have been significant improvements in recent years here as well. While a robust, web-based monitoring system typically adds a premium for a solar water heater, SES always installs a basic energy meter to quantify the system's production, at no extra charge.
