Feasibility study of a small SPV power plant added to existing rooftop BTS

This paper proposes a modification to the existing rooftop Base Transceiver Station (BTS) located in urban area. Due to growing subscriber base the telephone service providers (TSPs) are forced to install more rooftop BTS in densely populated urban areas amid tall concrete buildings. Due to huge running cost incurred on electric energy bills, fuel purchase and rentals, the TSPs are unable to run/maintain a wide spanning network. This scenario can be averted by adding a small solar photo voltaic power plant to existing rooftop BTS. This paper describes techno-economic optimum sizing of a small SPV power plant connected to existing rooftop BTS located in urban area. The prime concern is to determine PV array size for existing battery bank with limited area to install PV modules on rooftop.
