1. A parking lot device (PLD) adapted to be mounted in a parking lot comprising:
- a solar cell for capturing and converting solar energy into electrical energy;
an energy storage unit adapted to be connected to the solar cell for storing the electrical energy and providing electrical power supply to the PLD;
an energy level detector adapted to be connected to the solar cell for providing an indication when a level of energy captured by the solar cell is below a predefined energy level threshold set in such a manner to be indicative of a presence or absence of an obstacle shadowing the solar cell;
a memory storing a parking lot identifier associated with the parking lot;
a short range radio frequency transceiver (PLD SR RF Transceiver) adapted to be activated when the solar energy level is determined by the energy level detector to be below the predefined energy level threshold for transmitting a short range radio frequency signal comprising the parking lot identifier, wherein the transmitted signal is adapted to be received by a short range radio frequency transceiver associated with a parking vehicle device (PVD) located at vehicle parked inside the parking lot.

Abstract
There is provided a parking system comprising a parking lot device and a parking vehicle device configured for an enhanced management of power consumption such that the parking lot device uses self-generated energy and conducts tasks requiring a lower power consumption level and wherein the parking vehicle device uses the vehicle battery and is configured to conduct tasks requiring a higher power consumption level, where both the PLD and the PVD are configured to work in a coordinated manner to sleep and wake up only when required in order to minimize power consumption.
