METHOD FOR EVALUATING PHOTOVOLTAIC ENERGY PRODUCTION AND EVALUATION AND MANAGEMENT UNIT IMPLEMENTING THE METHOD

The invention concerns a method for evaluating photovoltaic energy production for an energy supply facility (11) installed on a site (1), the energy supply facility (11) comprising at least one electricity production unit (12) having at least one photovoltaic module (14); characterised in that the photovoltaic energy production evaluation method comprises the following steps: - determining past or predictive irradiance values for the site (1) on which the energy supply facility (11) is installed, the determination being carried out for time intervals of between one second and two years, and - evaluating the photovoltaic power generated as a function of the determined irradiance values and numerical values prerecorded in a database (30), this database (30) including, for each day of the year and different times of each day, prerecorded numerical values for determining the photovoltaic electrical power generated as a function of the irradiance. 本发明涉及一种对安装在场地(1)上的供能设施(11)的光伏发电进行评估的光伏发电评估方法，所述供能设施(11)包括至少一个具有至少一个
