description The invention discloses a photovoltaic tracking support start-stop control method and a photovoltaic tracking system, so as to reduce the damage probability of a rotating mechanism, a photovoltaic module and a photovoltaic tracking support. The photovoltaic module, an attitude sensor in the photovoltaic tracking system and the photovoltaic tracking support are always kept in the same attitude. Themethod comprises the steps of acquiring an inclination angle theta 1 of the photovoltaic module in the east-west direction and a rotation acceleration a1 of the photovoltaic module in the east-west direction by using the attitude sensor; judging whether theta 1-theta lim1 is less than or equal to theta th or theta 1-theta opt1 is less than or equal to theta th is met or not, wherein theta lim1 and theta opt1 are the limit angle and the expected angle of the photovoltaic module in the east-west direction respectively, and theta th is a set threshold value; if yes, sending a stop instruction toan east-west rotating mec
