  • Solar photovoltaic systems for rural communications

    Publication Year: 1990, Page(s):137 - 140
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (272 KB)

    By their very nature, rural communications systems require a large number of pieces of equipment operating in distributed locations, often in remote areas. Traditional forms of generation are ill equipped to provide small amounts of power in isolated locations. Solar electric photovoltaic (PV) systems, by contrast, are ideally suited to this set up. They are modular so can be easily configured to ... View full abstract»
