PURPOSE: A solar energy utilization system for a vehicle is provided to expand the usage range of solar energy and use the energy efficiently. CONSTITUTION: A solar energy utilization system(100) for a vehicle comprises a solar battery module(110), an engine operation circuit, an engine stoppage circuit, and a circuit selection switch(170). The solar battery module changes solar light into electric energy. The engine operation circuit is operated while an engine(190) is driven, and charges the battery(124) of a vehicle by using electric energy generated through the driving of an engine and the solar battery module. The engine operation circuit stores the energy output from the solar battery module in the battery according to the temperature in the outside, or supplies the energy to the blower(152) in a HVAC(Heating, Ventilation and Air Conditioning) of a vehicle or the preheating device(162, 164) of a vehicle. In case ignition ON signal is received, the circuit selecting switch cuts the circuit while engine driving and connects the circuit at the same time while engine being stopped. In case ignition OFF signal is received, the circuit selecting switch connects the circuit while engine driving and cuts the circuit while engine being stopped at the same time. |
