This document was created and published by the City of Tallahassee, Florida. It reports on the City’s use of a “Liberty Box”, which is a solar thermal system that provides power to water heaters. The technology was created by Energy Design Solutions, and was tested on an apartment complex in Tallahassee. Since the system utilizes wiring and not piping like a normal solar thermal system, the team was able to outfit the 2nd floor of the apartment building which can often prove difficult. The Maximum Potential Power Tracker (MPPT) system utilizes DC to provide current to resistive loads in water heaters, and the City found their test run to be successful.
