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. 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.
