A basic active direct photovoltaic module controlled solar water heating system will be installed at this residence. The system will consist of a 40 square foot solar collector and an 80 gallon solar storage tank. The collector will be roof mounted on the utility room roof. The water heater will be installed in an area in the utility room directly below the collector area.
Of special note is that the homeowner will construct a protective enclosure around the solar collector that can be used during hurricanes.
