Abstract
Within this study, single-cable propagation facilitated by PV strings’ wiring characteristics
is considered for an adapted design of PLC electronics. We propose to close the communications
signal path, resulting in a ring topology where a resonance condition could be implemented. A
PLC topology using the resulting circular closed-loop path of a PV series string as its physical
communication support is designed and leveraged for practical use. When the path length or the
number of transceivers is changed, the resonance properties that come with the circular path as
the physical support are affected but are shown to be preserved with the application of automatic
adjustable tuning. This automatic tuning guarantees that the resonance improves propagation
parameters and reverts the system to its optimal values at the chosen carrier frequency.
