solar-powered radio
A solar powered radio is a portable radio receiver powered by photovoltaic panels.{{cite web|url=http://earthship.org/Testimonials/Solar-Powered-Radio|title=Solar Powered Radio|publisher=earthship.org|access-date=2011-07-02}} It is primarily used in remote areas where access to power sources is limited.
History
Sarkis Acopian invented the first solar-powered radio in 1957. An experimental model, developed by General Electric, weighed just 10 ounces and was capable of working without light and recharging. It contained seven solar cells, four transistors and a small battery.{{cite web|url=http://www.ecofriend.com/entry/a-blast-from-the-past-solar-powered-radio-from-the-50s/|title=Blast from The Past – Solar Powered radio From the 50s|publisher=ecofriend.com|access-date=2011-07-02}}{{Cite web|url=http://www.ecofriend.com/a-blast-from-the-past-solar-powered-radio-from-the-50s.html|archive-url = https://web.archive.org/web/20160305152345/http://www.ecofriend.com/a-blast-from-the-past-solar-powered-radio-from-the-50s.html|archive-date = 2016-03-05|title = Blast from the Past – Solar Powered radio from the 50's|date = 21 November 2007}} In 1954, Western Electric began to sell commercial licenses solar powered radio, including other photovoltaic technologies.{{cite web|url=http://www.seia.org/galleries/FactSheets/Factsheet_solar%20history.pdf|title=The History of Solar Energy A Look at Uses of Solar Energy from BC to IT|publisher=seia.org|access-date=2011-07-02|url-status=dead|archive-url=https://web.archive.org/web/20100613033827/http://seia.org/galleries/FactSheets/Factsheet_solar%20history.pdf|archive-date=2010-06-13}} In 1957 the Acopian Technical Co. of Pohatcong Township, New Jersey, was reported as manufacturing the first solar radios for commercial sale to the general public.New Area Firm Markets Tiny Solar Battery Radio, Easton Express, May 11 1957.

Advantages
Solar powered radios eliminate the need to replace batteries, which makes operating them cost much less. Since they don't require plugs, they can be used in areas where there is no electrical grid or generators.{{cite web|url=http://www.greentechblog.org/solar-powered-radios-can-help.html|title=Solar Powered Radios Can Help|publisher=greentechblog.org|access-date=2012-12-20}} As a result, people in remote areas with little disposable income can have equal access to news and information. Informative radio programs, combined with solar powered radios, can be a powerful tool for improving the lives of people in remote areas.{{cite web|url=http://www.fao.org/fileadmin/templates/dimitra/pdf/dim_14_e.pdf|title=Rural radios and participatory communication|publisher=fao.org|access-date=2011-07-02}}
