More affordable than a full-house solar system, the SunSource Comfort System is a solar-assist technology that combines solar energy and electricity to reduce peak demand on home electric use. It operates in a wide range of sunlight and temperature conditions and is Energy Star qualified. The way it works is during peak daylight hours, the SunSource Comfort System gets help from a solar panel to heat and cool a home. It uses renewable solar energy to power the outdoor fan motor, reducing the utility-provided electricity needed for operation. The solar assist increases the system efficiency, reducing the power consumed by as much as 8%.
