Abstract
Provided are a power line communication device and the like capable of keeping attenuation of electric power of a control signal to a minimum. The power line communication device includes a communication unit (220) and a switch unit (SW). The communication unit (220) is connected in parallel to a PV panel (10) that is connected in series to a power line (PL), and communicates the control signal relating to power generation by the PV panel (10) through the power line (PL). The switch unit (SW) is connected in parallel to the communication unit (220).
