PROBLEM TO BE SOLVED: To provide an inexpensive mechanism for monitoring whether or not a photovoltaic system generates power as initially planned.SOLUTION: A power generation amount indicated by electrical energy information DEtransmitted from a photovoltaic system 1-m is the latest hourly actual power generation amount Eof the photovoltaic system 1-m, and electrical energy E produced by substitution of an air temperature Tand a quantity of solar radiation Gs in meteorological information DM transmitted from a meteorological information delivery server apparatus 60 into Equation (5) is the latest hourly assumed power generation amount E' of the photovoltaic system 1-m. Whether there is an anomaly in the power generation status of the photovoltaic system 1-m is determined on the basis of the power generation amounts. |
