Abstract: A solar power system and control for a vehicle with an air conditioning system includes a solar panel unit, a voltage regulator, an electric drive motor, a user interface, and a thermostat controller. The solar panel unit is mounted on the vehicle. The voltage regulator is electrically connected to the solar panel unit and a power storage device of the vehicle. The electric drive motor is mounted to the vehicle and drivingly connected to a compressor of the air conditioning system. The user interface includes a system activate user input device configured to generate and transmit a system activate signal. The thermostat controller is communicatively connected to the user interface to receive the system activate signal; and configured to selectively provide electric power to the electric drive motor, the condenser fan electric motor, and the blower fan electric motor, at least in part, in response the activate system signal.
