The invention discloses a solar photovoltaic performance prediction method based on meteorological data analysis, which comprises the following steps of acquiring the real-time power eta of the solarequipment, the temperature Tp of the solar equipment battery panel, and the solar energy irradiation intensity power G eta of the solar equipment; obtaining the power generation E in the sample time by the formula. By the adoption of that technical scheme, a simple method is established to obtain the photovoltaic cell power output E in a certain period of time, a mean solar irradiation intensity,average ambient temperature and average ambient wind speed, which are easily obtained, are introduced into the prediction of photovoltaic power generation E through thermodynamic modeling and analysis. On the premise that the prediction results are accurate enough, the calculation method is simpler, and the dependence of the prediction method on meteorological data can be greatly reduced.
