Abstract :
The state of incessant power failure accompanied with the increase in pump price of petroleum in Nigeria, solar energy becomes the most sought after energy source. Solar chargers are simple, portable and ready to use devices which can be used by anyone especially in remote areas. Going solar can solve the problems of dependence on fuels and the prevalent energy crisis. This project aims to make a portable solar charger which can be used on the go. A portable solar mobile phone charger is simply a power electronic device that converts solar radiation into electrical current for the purpose of charging the batteries of mobile phones. This charger is made by converting, controlling and conditioning the flow of electrical energy from source to load according to the requirements of the load; this technology is called power electronics. An external adjustable voltage regulator is used to obtain the desired constant voltage. A zener diode switches on to ensure charging is cut off at the saturation point. Two 3.7V lithium ion batteries are used as backup; an operational amplifier works here as a comparator to signify when backup is fully charged. Ultimately, 11V and 160mA is supplied by the panel under full sunlight. This charger has an output voltage of 5V and an average of 800mA current to charge a mobile phone, this system charges a phone fully between 4-5hours and it has a capacity of 4800mAh. This device charges all mobile phones by all manufacturers using a universal serial bus connector. It is the only viable solution to charging mobile phones as it is portable, light-weight and does not cause pollution.
