METHOD OF EVALUATING AMOUNT OF POWER GENERATED BY FIELD PHOTOVOLTAIC POWER GENERATING SYSTEM, COMPUTER-READABLE RECORDING MEDIUM RECORDING EVALUATION PROGRAM, AND EVALUATION SYSTEM

摘要

PROBLEM TO BE SOLVED: To provide a method of forming an I-V curve which is high in accuracy and general-purpose properties, and to provide a method of evaluating the amount of power generated by a field photovoltaic power generating system by the use of the above I-V curve.

SOLUTION: Two methods (one is a monthly temperature coefficient method and the other is a temperature-corrected system output coefficient method) for calculating efficiency obtained by adding a loss caused by a temperature rise to a system output coefficient are developed, and it is made clear that the calculation results obtained through the two methods are very similar to each other. It is found that both methods become more effective when a method of forming an I-V curve through a theoretical formula is employed as a method of forming an I-V curve at an optional insolation intensity and a solar cell temperature.
