A solar-thermal powered recreational vehicle featuring a solar-thermal air conditioning system integrated with a solar clean energy system to provide a recreational vehicle having improved energy efficiency. In an embodiment employing the principles of the present invention, the solar-thermal powered recreational vehicle can comprise a clean energy system for providing electrical power to the recreational vehicle, whereby the clean energy system features one or more solar photovoltaic panels, a batter bank, and a generator operatively coupled to a hybrid inverter. The solar-thermal air conditioning system is powered by the clean energy system, with the solar-thermal air conditioning system featuring a solar-thermal collector panel functioning to superheat compressed refrigerant prior to the compressed refrigerant being transmitted to the condenser. Because the compressor is the most energy-intensive component in the traditional direct expansion AC system, the use of free solar energy by the present invention to reduce the work load on the compressor significantly reduces the overall energy requirements of the recreational vehicle, thereby providing a recreational vehicle capable of operating on solar and battery power alone for significant periods of time.
