METHOD FOR SIMULATION-CALCULATING SOLARLIGHT GENERATING AMOUNT AND COMPUTER READABLE DATA STORAGE MEDIUM WITH CALCULATING PROGRAM RECORDED THEREIN

摘要

PROBLEM TO BE SOLVED: To solve the problem that since a general method for drawing I-V, P-V curves in a designated solar radiation intensity/solar battery temperature from characteristics values (Isc, Iop, Vop, Voc,α,β, Rs, K) in a reference state (solar radiation intensity 1 kw/m<2> , solar battery temperature of 25 deg.C) of the solar battery is not established, a method for accurately calculating the monthly and yearly solarlight generating amounts by simulating for general purpose is not sufficiently established. SOLUTION: A method for calculating by simulating the solarlight generating amount comprises the steps of (1) obtaining basic characteristic value (IL, Co, n, Rsh, Rs) at 20, b and c deg.C as a general purpose method for forming the I-V curve at the solar radiation intensity, solar battery temperature designated from the I-V curve of the reference state, obtaining the basic characteristic values at the designated temperature by a curve interpolation, obtaining the values by a Newton method by using these values, and forming the I-V curve. Or, the method comprises the steps of (2) converting the points of the I-V curve of the reference state via a 'practical I-V curve conversion formula', and forming the I-V curve. The generating amount is calculated by simulating by applying these two methods to a practical use and as a core part of the 'solarlight generating amount simulating calculating program'.
