SOLAR POWER GENERATION AMOUNT PREDICTION DEVICE, SOLAR POWER GENERATION AMOUNT PREDICTION SYSTEM, PREDICTION METHOD, AND PROGRAM

摘要

A power generation amount record acquisition unit (4) acquires, from a power amount measurement device (3), a power generation amount record for the amount of power generated by a solar power generation system (2). An extraterrestrial solar radiation amount calculation unit (7) calculates the extraterrestrial solar radiation amount on a designated day and in a designated time period at the location at which the solar power generation system (2) is installed. A weather information acquisition unit (10) acquires weather forecast information for each time period of a day for which a prediction is to be made. A power generation amount record classification unit (8) classifies power generation amount coefficients, obtained by dividing a power generation amount by an extraterrestrial solar radiation amount, into a given number of power generation amount record groups associated with weather attributes. A predicted power generation amount calculation unit (11) calculates a predicted power generation amount on the basis of the extraterrestrial solar radiation amount in each time period for which a prediction is to be made, and the power generation amount record group associated with a weather attribute corresponding to the weather forecast information.
