A case study of Solar Powered Base stations
ABSTRACT Green power, environment protection and emission reduction are key factors nowadays in the telecom industry. Balancing of these modes while reducing the capital
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.
Cellular base stations powered by renewable energy sources such as solar power have emerged as one of the promising solutions to these issues. This article presents an overview of the state-of- the-art in the design and deployment of solar powered cellular 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.
The following configurations are common for solar powered BSs: Solar stand alone: The BS is powered solely by solar power and the batteries. Grid-connected: The BS is powered by energy har- vested from PV panels, but in case it falls short, power from grid is used.
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.
