A solar gardening system includes a cultivation box； an LED lamp assembly for illuminating the cultivation box； and a power source including a photovoltaic system including a plurality of solar modules electrically connected together, a controller electrically connected to the solar modules, and a rechargeable battery electrically connected to the controller wherein the controller is configured to cause the rechargeable battery to supply electricity to the LED lamp assembly. The LED lamp as light source for plant growth can save energy and prolong lifecycle. Further, the LED lamp can emit monochrome with narrow wavelength. Moreover, the number of LED lamps can be increased or decreased depending on growth seasons so as to provide sufficient illumination to plants being grown. Thus, plants can be well grown.一種植物栽培系統，包括栽培箱、植物生長燈及用於對負載供電的電源，該植物生長燈為發光二極體(下稱LED)燈，該電源至少包括光伏發電系統，該光伏發電系統包括依次連接的太陽能電池元件、控制器和蓄電池組，該控制器直接或間接地與該LED燈連接。通過太陽電池進行光電變換成電能，可有效的代替傳統電源或作為補充電源的動力，並實現照射光的合理配置，可以得到更好的植物生長效果。
