PURPOSE: A greenhouse is provided to get a power that is needed to heat the greenhouse; to control the heating temperature of greenhouse and to manage the amount of artificial light which is needed for the cultivation of crops. CONSTITUTION: A greenhouse comprises a solar cell array(101) which converts with photoelectricity from the light energy of the sun into the electricity, a sunlight condenser(102) which condenses the electricity which has been through photoelectric conversion from the solar cell array; a planar heating element(200) which emits heat getting the condensed power in the sunlight apparatus sunlight condenser; an LED lightening(300) which lightens getting the condensed power from the sunlight apparatus sunlight condenser; a control unit which controls the switching of power supply for the operation of the planar heating element and the LED lightening according to the preset condition controlling the power supply which is condensed in a sunlight condenser; and multiple cultivation shelves(500) having the multilayer structure of rent building type. The solar cell array is installed in a semi circle type on the roof of green house in ultra thin form. The LED lightening is formed combining one or more than two of the first LED lightening which is arranged in the center of ceiling along with the length direction of green house; the second LED lightening which is arranged on the left or right side following the length direction of the green house; and the third LED lightening arranged on the side of multiple cultivation shelves which is installed inside of the greenhouse. The control part additionally includes a temperature sensor(401) to measure the internal temperature of the greenhouse.
