....Telecommunication equipments such as mobile phones, broadcasts, radio transmissions, emergency phones, and satellite communication become more and more important in our daily lives. But when natural disasters strike, the electricity supply is often damaged or destroyed. Then there won't be any communication available which can result in serious consequences. For example, after the natural disaster strikes, the immediate communication with the rescue team is required in order to help any people who are injured or in danger. Thus it is also important to have a working telecommunication system in those areas that are out of reach of a sustainable electricity supply.
....In those cases, if we can use solar energy to generate the electricity needed for the telecommunication equipments most of these problems can be solved.
