SOLAR BATTERY POWER GENERATING AMOUNT SIMULATOR

摘要

PROBLEM TO BE SOLVED: To provide a solar battery power generating amount simulator capable of simulating a power generating amount of a solar battery based on an accurate temperature of a solar battery module without diverging. SOLUTION: The solar battery power generating amount simulator comprises a reference current arithmetic unit 4. The arithmetic unit 4 obtains an I-V curve at a solar radiation energy of 1 kW/m2 and a solar battery temperature of 25 deg.C when the generating amount at each temperature is obtained when the energy is 1 kW/m<2> . That is, the unit 4 calculates a generating current I at each voltage value in the above-mentioned reference state. Then, as the energy, a value stored in a database 5 is used corresponding to a standard day of a season for simulating the generating amount. The simulator further comprises a power generating amount correcting unit 5. The collecting unit 5 corrects the generated current and voltage in the I-V curve corresponding to the temperature to be simulated by using a correction formula for correcting the generated current according to the temperature.
