Embedded photovoltaic monitoring device, system and method

An embedded PV monitoring device comprises a data receiving unit, a processing unit, a simulating unit and an evaluating unit. An embedded PV monitor system comprises a PV unit, a sensing unit and an embedded PV monitoring device. An embedded PV monitor method mainly utilizes the monitoring device to receive voltage and current parameters of the PV module and an environment working parameter. An output current and an output power of the PV module can be actually calculated, while the output current and the output power of the PV module can be simulated and estimated according to the voltage parameter and the environment working parameter. Thus, the field test monitoring and evaluating on the PV module can be automatically performed and a warning message can be timely outputted. This is advantageous to the detection of the yield of the PV module and the increase of the production quality.
