Design and Construction of a Portable Charger by Using Solar Cap
Sun is a source of renewable energy called solar energy. Solar energy is a basic need of living plants and human being on the earth. By the use of solar energy there is no pollution and no waste. There are many fields of using solar energy. It can be used directly in a variety of thermal applications like heating of water or air, charging batteries, drying, distillation, cooking etc. Bangladesh is an under developing country. It is a country of lot of problems. Energy crisis is one of the important problems. To overcome this problem solar energy may be used as an alternative. It is not possible to solve the giant problem over a night but it can be decreased. Solar energy is one kind of renewable energy. Everyday a lot of power is used for charging purpose like mobile, camera, light etc. Those devices can be easily charged by using solar charger. In this project a solar cap is designed and constructed for charging mobile phone, camera etc. which is nothing but a solar panel based charging system. Here a solar panel is placed on a cap. An USB port is attached with the panel. A cable is connected with the solar panel and the device that will be charged. At day time the device can be easily charged by using this solar cap. If the device is fully charged then the extra charge can be stored in a reservoir. So, by using the charger the devices can be charged day and night.
