[0060] Finally, the actual output electric power of the photovoltaic panel 3 is calculated by considering the parallel resistance in the equivalent circuit of the photovoltaic components in the photovoltaic panel 3.

[0061] The controller controls the alarm based on the temperature sensor. The controller compares the actual output power of the photovoltaic panel 3 with the preset output power range.
