The document proposes installing solar photovoltaic systems at two bus stands in Coimbatore, India. It assesses the solar potential and estimated electricity loads at the sites. The Moffusil Bus Stand system would have a 26 kW capacity and the Town Bus Stand system 32 kW capacity. Cost estimates are provided for installing the systems, which would save money on electricity costs and reduce carbon emissions. Installation is recommended along with estimated payback periods and carbon credit benefits.
