The invention relates to a multistage reduced pressure distillation separation device and method for photovoltaic bio-oil, the multistage reduced pressure distillation separation device comprises a reduced pressure distillation unit, the reduced pressure distillation unit comprises a flask and a vacuum distillation column, the flask is filled with bio-oil to be distilled, the feeding unit is connected with an inlet of the flask, and the multi-stage condensation unit is connected with the outlet of the vacuum distillation column and is used for realizing step-by-step separation and refining ofthe bio-oil. The reduced pressure distillation instrument disclosed by the invention has the characteristics of rectification and membrane separation, so that bio-oil colloid removal and residue separation can be effectively realized, and multi-component continuous separation can be effectively realized through the multi-stage condensing device. The photovoltaic power generation device is used forreplacing conventional po
