APPARATUS AND METHOD FOR ANALYZING POWER GENERATION OF PHOTOVOLTAIC POWER GENERATION SYSTEM

摘要

The present invention relates to an apparatus and method for analyzing power generation of a photovoltaic power generation system, which enables a user to easily maintain the photovoltaic power generation system by analyzing the power generation time and rate of photovoltaic power generation during a time period (day, month, or year) designated by the user. The apparatus according to the present invention comprises: a plurality of photovoltaic power generation parts including solar cell modules for converting solar energy into electrical energy and outputting the electrical energy; a photovoltaic power generation measuring part, arranged in each of the photovoltaic power generation parts, for measuring the atmospheric temperature, the temperature of the solar cell modules, the quantity of horizontal solar radiation, the quantity of incident solar radiation, and the power generation time and amount; a photovoltaic power generation analysis part for analyzing the power generation time and rate of the photovoltaic power generation part, per site or overall in which each of the photovoltaic power generation parts is arranged, on the basis of various pieces of information measured in the photovoltaic power generation measuring part; and a photovoltaic power generation monitoring part for monitoring power generation status, surveillance, diagnosis, analysis, and reports in real-time by receiving various information diagnosed by the photovoltaic power generation analysis part over a network.
