Abstract: A novel method for monitoring the operation of a solar thermal system such as the healthy home system or the like. The present device includes a hardware housing with a processor device coupled to a bus and one or more memory devices. The processor device can be coupled to one or more input devices wherein the one or more input devices are coupled to at least the solar array. The input devices can be coupled to the electric panel, the space heater, the water heater, as well as other components of the healthy home. The method includes a variety of steps such as establishing connection to associated hardware in the healthy home system, running diagnostic checks to determine system health, validating acquired data, and displaying the data through text display and graphical illustrations. The method also includes updating the system information according to a schedule scheme such as a polling scheme, interrupt scheme, or others.
