Claim:
1. A method for calculating a solar radiation amount, comprising an information processor collecting a power value generated by a photovoltaic (PV) array and output from a power conditioner of an emergency management system (EMS) unit, and storing the power value in a storage unit for: calculating a first solar radiation amount and a panel temperature based on a measured power value of a solar panel; calculating a first temperature correction coefficient; calculating a power value of the solar panel based on the first solar radiation amount, the panel temperature, and the temperature correction coefficient; calculating a correlation coefficient by comparing the measured power value and the calculated power value of the solar panel; determining whether the correlation coefficient has a highest value; adjusting, based on the determination, the first temperature correction coefficient to a second temperature correction coefficient so that the correlation coefficient has the highest value; calculating an outside air temperature based on the panel temperature using the second temperature correction parameter corresponding to the correlation coefficient having the highest value; calculating a second solar radiation amount based on the calculated outside air temperature; and using the second solar radiation amount to perform energy management on an EMS associated with the solar panel.
