solar powered BS typically consists of PV panels, bat- teries, an integrated power unit, and the load. This section describes these components. Photovoltaic panels are arrays of solar PV cells to convert the solar energy to electricity, thus providing the power to run the base station and to charge the batteries.
Base stations that are powered by energy harvested from solar radiation not only reduce the carbon footprint of cellular networks, they can also be implemented with lower capital cost as compared to those using grid or conventional sources of energy . There is a second factor driving the interest in solar powered base stations.
BSs are categorized according to their power consumption in descending order as: macro, micro, mini and femto. Among these, macro base stations are the primary ones in terms of deployment and have power consumption ranging from 0.5 to 2 kW. BSs consume around 60% of the overall power consumption in cellular networks.
This in turn changes the traffic load at the BSs and thus their rate of energy consumption. The problem of optimally controlling the range of the base stations in order to minimize the overall energy consumption, under constraints on the minimum received power at the MTs is NP-hard.
Among these, macro base stations are the primary ones in terms of deployment and have power consumption ranging from 0.5 to 2 kW. BSs consume around 60% of the overall power consumption in cellular networks. Thus one of the most promising solutions for green cellular networks is BSs that are powered by solar energy.
