How Solar Energy Systems are Revolutionizing Communication Base Stations?
Various policies that governments have adopted, such as auctions, feed-in tariffs, net metering, and contracts for difference, promote solar adoption, which encourages the use
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 stateof- the-art in the design and deployment of solar powered cellular base stations.
Multiple requests from the same IP address are counted as one view. Energy efficiency and renewable energy are the main pillars of sustainability and environmental compatibility. This study presents an overview of sustainable and green cellular base stations (BSs), which account for most of the energy consumed in cellular networks.
4.1.1. System Model of Solar-Powered BS A solar-powered BS typically comprises photovoltaic (PV) panels, batteries, an integrated power unit, and the load as shown in Figure 6. Connected via an open switch, the DG acts as a backup power source in the case of malfunctions as discussed in the second paragraph of Section 4.1. Figure 6.
A feasibility study conducted on a solar PV system in grid-connected BS sites was presented in [ 116 ]. To achieve the most economically feasible configuration, BSs in Bangladesh must have 2.5 kW PV and sixteen batteries in two parallel strings, as well as two 4 kW DGs with an energy cost of $ 1.657/kWh.
