<p>A system for monitoring a state of operation of a photovoltaic panel (P). The system comprises a transponder (T) for connection to the panel (P), wherein, when the panel (P) is in a first state of operation, the transponder (T) transmits an individual identifier code in response to a pre-determined received signal and wherein, when the panel (P) is in a second state of operation, the transponder (T) does not transmit the individual identifier code.</p> |
